I&#;ve seen poor quality power supplies fail in spectacular ways.

In my years of IT work, the smell of burnt plastic from cheap power supplies dying was all too common.

For the fortunate ones, only the PSU was toast. For others, it took the motherboard with it.

It can be tempting to grab a $40 power supply and use the extra cash toward a better graphics card or bigger solid state drive.

Don&#;t do it!

It&#;s absolutely worth it to spend a little extra for quality when it comes to your power source.

In the guide that follows, I&#;ll detail what to look for in your power supply and whether Corsairor EVGA is a better choice for your PC.

Quick Pick: The Corsair RMx is quiet, reliable, modular, and has plenty of power for most PC&#;s.


Watts vs Price &#; Finding the Right Balance

Power supplies reach as high as W and can cost several hundred dollars.

Fortunately for your wallet, high end power supplies are overkill for most PC&#;s.

In fact, a W power supply is plenty for most gaming and productivity PC&#;s.

Planning to overclock and/or go with the highest-end single video card available? I&#;d step up to a W or W model.

Beyond W is typically only useful if you&#;re running multiple GPU&#;s or CPU&#;s.

The best way to ensure you select the right wattage is to use a calculator.

Outervision&#;s calculator simplifies this. It allows for some &#;wiggle room&#; if you make minor changes to your system in the future.

Hit the &#;Basic&#; tab on the calculator above, enter your build&#;s details, and click &#;Calculate.&#;

You&#;ll be all set if you pick any model at or above the &#;Recommended&#; wattage given in the calculator.


All devices which run on electricity lose a certain amount of their power input.

If a PSU is 80% efficient, that means 80% of the power being pulled from the outlet is used and 20% is wasted.

Inefficient power supplies have a big impact on a PC.

Power lost to inefficiency is given off as heat.

More heat in your PC means faster fan speeds to expel the hot air. This in turn creates more noise. Too much heat and you&#;ll run into stability issues.

Also, more electricity is needed to output power to your components. If you run your system several hours a day, or 24/7, it&#;ll have an impact on your power bill.

Thankfully, power supplies are much more efficient for the price than they used to be.

All good power supplies are given an efficiency rating based on the &#;80 PLUS&#; standard.

As the name suggests, to be given this rating the PSU needs to be at least 80% efficient.

Here&#;s what the different levels look like:

  • 80+ or 80+ White: 80% power efficient
  • 80+ Bronze: 85% power efficient
  • 80+ Silver: 88% power efficient
  • 80+ Gold: 90% power efficient
  • 80+ Platinum: 92% power efficient
  • 80+ Titanium: 94% power efficient

To start with, I recommend no lower than 80+ Bronze.

The price difference between Bronze and a standard 80+ or a non-rated power supply from the same brand is minimal. You&#;re likely to make up the small price difference over the lifetime of the computer in electricity savings.

Corsair and EVGA don&#;t offer much in the way of Silver rated units.

80 PLUS Gold is the current &#;sweet spot&#; for power supplies.

There&#;s an efficiency gain of 10% over standard 80+ and 5% over Bronze.

The 80+ Gold units have better quality components and larger fans. All of Corsair&#;s and EVGA&#;s Gold PSU&#;s (except TX series) are efficient enough that the fan isn&#;t even needed at idle or during basic tasks like web browsing

Cost is a step up from Bronze models, but there are plenty of choices for under $

How about Platinum and Titanium?

These models are quite a bit more costly. In most cases wouldn&#;t spend extra only for the sake of the extra efficiency.

With Platinum and Titanium PSU&#;s, you do get the best quality components, a full set of features, and high power ratings.

Building a high-end system? You&#;re typically looking at a $ price increase to go from a Gold to a Platinum/Titanium PSU. They&#;ll generate a bit less heat and slightly reduce the power draw from the wall.

Like what you see based on the features and power rating? Does the price still keep you within your budget? The improved efficiency of a Platinum or Titanium PSU is a nice added bonus.

Non Modular, Semi Modular, or Fully Modular

Modular in this case means separate cables used to connect the PSU to other components.

Which type of cabling you choose depends mainly on your budget.

Non Modular

Basic power supplies will come with one large bundle of cables hard-wired to the power supply.

This saves a bit on cost, so you&#;ll see non-modular cabling used in most entry level PSU&#;s.

There are some downsides to having all your power cables hardwired:

  • Unused cables remain inside your PC and take up space
  • Air flow can be affected if extra cables are left in the way
  • All cables in the bundle are a fixed length
  • Each component must be disconnected to remove the PSU

While these are fairly minor issues for most system builders, you might find it worth spending a little extra if cable management is important to you.

Semi Modular

For what usually amounts to a small price increase of $, semi modular PSU&#;s make a big difference in cable management.

The main pin ATX power connector is still hard wired &#; but since every motherboard needs this cable, you wouldn&#;t be leaving it off anyway.

Every other cable on EVGA and Corsair semi modular PSU&#;s is optional.

If you have an M.2 SSD and no other drives, you can skip connecting the SATA cables entirely.

Single GPU systems can leave out the extra PCIe power cable that&#;s meant for SLI and Crossfire setups.

By using exactly as many cables as you need, you can avoid creating a rat&#;s nest of wires inside your PC that restricts airflow. Plus, minimizing the cables just looks better.

Semi modular is my go-to choice for value and usability.

Fully Modular

High end PSU&#;s usually are fully modular, meaning every cable (including the pin ATX) is removable.

I don&#;t usually recommend spending more money just for the sake of upgrading from semi to full modular.

That said, maybe you already have your eyes on a certain model and it&#;s fully modular.

If that&#;s the case, there are some nice things about every cable being removable:

  • The PSU can be removed for cleaning or replacement with no rerouting of cables
  • A longer or shorter pin ATX cable can be substituted
  • Custom sleeved cables are more easily made or purchased

Between semi and fully modular, the choice comes down to whether you want to have the best possible aesthetic and cable management inside your build.

Side by Side Comparisons

Corsair CXM vs EVGA B3

A W PSU is a great choice for the average PC.

The types of PC these power supplies are good for:

  • Low to mid-range graphics card
  • Air cooling
  • Minimal overclocking
  • Running a few hours per day; powered off the rest

Let&#;s look at whether Corsair or EVGA is the better pick at W.

Power and Efficiency

Both models here output W of continuous (not peak) power. The single-rail 12V power output is identical on both at A.

They&#;re both similarly efficient with 80 PLUS Bronze ratings.

Let&#;s move onto what makes them different.


The CXM is a semi-modular power supply, meaning the 12V ATX cable is hard-wired.

The B3 is fully modular &#; the ATX cable is separate should you choose to replace it with a longer, shorter, or custom sleeved cable. The remaining connections are divided up into 5 modular cables rather than 4 on the Corsair, which can help a bit with routing to SATA drives.

The B3 has an Eco mode that can be enabled with a switch on the back. This allows for silent operation under low loads by halting the fan when it&#;s not needed. This is not possible on the Corsair.


The Corsair on average sells for about $5 less. If Eco mode and better cabling aren&#;t important to you, I&#;d save the money and go for the Corsair.

Otherwise, for the small price difference I think EVGA is a better value here.

Overall Winner: EVGA B3


Corsair CXM vs EVGA BQ

W PSU&#;s are fairly popular in gaming PC&#;s. They allow for some overclocking and can support most any graphics card.

Here&#;s the type of PC I&#;d recommend these W PSU&#;s for:

  • Mid to high-end single graphics card
  • Air cooling or All-in-one liquid cooler
  • Mild overclocking
  • Running a few hours out of the day, otherwise off

Power and Efficiency

The W rating on both models is the continuous power output rather than peak, which is good. The 12V rail output is the same between brands at 54A.

Both have about the same efficiency and were given 80 Plus Bronze ratings.


Features are very similar here.

Both have semi-modular cables. Neither model has an Eco mode for zero-RPM fan operation &#; look elsewhere if silent operation at idle and low loads is important.

The EVGA BQ is about 25mm/1 inch longer, but houses a larger mm compared to Corsair&#;s mm.

Despite this, the EVGA isn&#;t much quieter. Both models have low noise levels up to about W, but get fairly loud under heavier loads.


Both sell for identical prices, and offer 5-year warranties.

Overall Winner: Tie, but I recommend skipping both models and moving up to an 80 PLUS Gold PSU (TXM, RMx, or Supernova G3)

Corsair RMx vs EVGA SuperNOVA G3

A W 80 PLUS Gold power supply is my recommendation for most gaming PC&#;s. They&#;re a good pick for many workstations as well.

Here&#;s where I&#;d recommend a W PSU:

  • High end single GPU or two mid-range GPU&#;s
  • Air cooling or an AIO liquid cooler
  • Overclocked CPU/GPU/RAM
  • Running up to 24 hours/day

Let&#;s see whether Corsair or EVGA is the better pick.

Power and Efficiency

Continuous output (not peak) is W as the names suggest for both models. Corsair and EVGA each have single 12V ATX rails at A and A, respectively.

Both PSU&#;s are 90 PLUS Gold rated. The EVGA is slightly more efficient on average, but both perform very well.


These are fully featured power supplies suited for most any PC.

The big difference between brands here is the noise level. The RMx&#;s fan profile keeps the fan speed at zero up until around W of power draw. From there, it ramps up gradually and is still near-silent. It&#;s unlikely to be heard over other fans in your PC.

The SuperNOVA does have a zero RPM fan mode as well, but beyond about W the fan starts to run. It ramps up pretty quickly from there and unfortunately is quite noisy at W and beyond.

The fan on the Corsair is only slightly larger at mm vs mm; the noise issue seems to be simply due to the fan profile of EVGA&#;s PSU.

Both models have fully modular cables. EVGA includes six total PCIe power connections (for 3 GPU&#;s) compared to 4 with Corsair. Keep in mind if you plan to power 3 GPU&#;s, they would need to be somewhat low-end for this PSU to handle them. Otherwise cabling is similar.

Length of the SuperNOVA is a bit shorter at mm in comparison to mm on the RMx.


Both the RMx and the G3 have excellent warranties at 10 years.

Prices have fluctuated, but typically they&#;re within $10 of each other, with the Corsair often being slightly cheaper.

Due to the much quieter fan profile, I think the Corsair is the better value here.

Overall Winner: Corsair RMx


Corsair RMx vs EVGA SuperNOVA G3

Moving from W to W gives a bit more headroom for high-end hardware and overclocking.

Power and Efficiency

As with all other Corsair and EVGA models, power numbers are rated in continuous rather than peak power. So, you get the full W with both models.

These PSU&#;s are both 80 PLUS Gold certified so they&#;re great for 24 hour/day use. Average efficiency is nearly identical.

Both the RMx and SuperNOVA output A to their 12V rail.


The Corsair and EVGA both are fully modular and have all the features you&#;d expect. They&#;re both compact, with the RMx being mm in length. The SuperNOVA is even smaller at mm.

As we saw with the SuperNOVA , the fan noise is what sets these two models apart.

The RMx is one of the quietest power supplies out there whether at medium or heavy load. The EVGA gets quiet load at anything but a low load.


Both models include a year warranty, which is great at this price point.

Prices have actually gone up on the SuperNOVA over time, with the RMx typically being available for $ less.

Between the louder fan noise issue and the higher cost, I only recommend the SuperNOVA if you have a compact case which can&#;t fit a mm PSU.

Overall Winner: Corsair RMx


Corsair RMx vs SuperNOVA G3

High-end system builders might opt for a W power supply. The number just looks impressive, doesn&#;t it?

Here&#;s the type of PC where it makes sense to spend the extra money on a W power supply:

  • Up to two high-end GPU&#;s
  • Air, AIO water, or open loop/custom liquid cooling
  • Overclocked CPU/GPU&#;s/RAM
  • Running as much as 24 hours/day

Power and Efficiency

Corsair and EVGA both advertise their power ratings with a continuous value. That&#;s good, because you can use close to the full W instead of being misled by a &#;peak&#; rating.

12V rail output moves up to an impressive A with both models.

Average efficiency is very similar between the RMx and SuperNOVA , with the SuperNOVA coming out a bit ahead.


Both the Corsair and EVGA are fully modular and compact in size. The Corsair was updated, reducing the length from mm to mm. The EVGA is shorter still at mm.

These PSU&#;s offer a fanless mode at low loads.

I&#;m going to sound like a broken record here &#; but as with the other RMx vs SuperNOVA G3 comparisons, fan noise at medium to high load is much less noticeable on the Corsair. If noise is a concern, this should make the decision easy


10 year warranties come standard for both these models which offers some great piece of mind.

Pricing of the two models was similar at release. However, the EVGA&#;s price has drifted upward lately and it&#;s usually $ more expensive.

Combined with the better fan profile of the Corsair, I only recommend the EVGA if noise isn&#;t much of a concern and you need a shorter mm PSU for your compact case.

Overall Winner: Corsair RMx


Corsair AXi vs EVGA SuperNOVA T2

Moving up to the big leagues, we have two powerhouse W PSU&#;s.

Keep in mind you&#;ll see better efficiency if you size your power supply appropriately, so don&#;t go for a W model when W is plenty.

That said, here&#;s the type of PC you might consider a W PSU for:

  • Three to Four high-end GPU&#;s
  • Dual CPU&#;s
  • Custom water cooling
  • Extreme overclocking

Power and Efficiency

No messing around with power specs. The advertised W rating is available as continuous power, rather than peak, for both brands.

When you&#;re pulling a lot of watts, efficiency is important for both your power bill and heat output. Better efficiency means lower operating temps.

Both power supplies have been given the top 80 PLUS Titanium certification. Test results showed both the AXi and SuperNOVA T2 have excellent efficiency, exceeding their ratings in some cases.

The AXi comes out slightly ahead in average efficiency throughout its range. But, the SuperNOVA T2 is close behind it and still one of the most efficient on the market.

12V rail power is bonkers at A for both power supplies.


These, of course, are fully modular PSU&#;s. They include plenty of PCIe and CPU/EPS cables to support systems with up to two CPU&#;s and four GPU&#;s.

The fan in the Corsair stays still up to about W, while the EVGA doesn&#;t run until W. The fan profiles for both models keep them very quiet at everything short of about ~W. Noise level should not be an issue with either PSU in normal use.

The standout between these two models is that the AXi is a digital power supply while the SuperNOVA is not.

Digital PSU&#;s give you access to full monitoring of the power supply via software. In this case, it&#;s named Corsair Link. You can view output across the individual rails, temperature, fan speed, and efficiency. Very cool stuff if you like to monitor every detail of your PC.


W PSU&#;s can be pricey, but they&#;re still relatively affordable compared to other high end components such as CPU&#;s and GPU&#;s.

There&#;s a clear winner on value between the two options compared here. The Corsair has been steadily dropping in price, while the EVGA has stayed about the same since release. This puts the AXi around $ cheaper on average.

Add in the fact that the Corsair is a digital power PSU with monitoring features and I think it&#;s a much better value.

Overall Winner: Corsair AXi



We PC builders have it pretty good in terms of warranty.

Most premade computers (and electronics in general) have a pathetic 1-year warranty.

Not the case with power supplies from a reputable brand.

Good PSU&#;s use high quality components. They often last for the lifetime of the computer. Since they last so long, the makers can afford to provide a long warranty.

Corsair and EVGA both give you a 3-year warranty at the very minimum.

Going with a W or higher 80 PLUS Bronze power supply gets you a 5-year warranty on most units from either brand.

Most 80+ Gold PSU&#;s from Corsair and EVGA include a 7-year warranty or better.

Finally, most 80+ Platinum and Titanium power supplies from either brand step up to a year warranty.

Which brand handles the process better? I&#;ve had good experiences with both, matching what I&#;ve seen of their reputations online.

Corsair quotes days for returns to be processed while EVGA states days is typical. Add on business days for the replacement to be shipped to you.

Advanced RMA

I highly recommend an &#;Advanced RMA&#; aka &#;cross shipping&#; should you ever need to get a warranty replacement of a critical component like a power supply.

Fortunately, both brands offer this.

You&#;ll need a credit card for this process. The manufacturer places a hold on your card &#; usually around the MSRP price of the PSU. This is just in case you never send back the defective power supply.

Corsair/EVGA ships out a new power supply so you can get up and running faster. Once they receive the defective part back, they take the hold of your card and you&#;re done.

Obviously, your PC can&#;t function without power. This is a great way to get back up and running without a long wait

Fans and Noise Level

Air cooling has come a long way, and power supplies have benefited greatly.

You won&#;t find small, noisy, high-RPM 80mm exhaust fans in any of EVGA or Corsair&#;s PSU&#;s.

mm fans are the new standard, with up to mm offered in higher-end models.

Larger fans offer more airflow despite lower rotational speeds. As a result, even under heavy load these power supplies don&#;t generate a lot of noise.

If quiet operation is good enough for you, no offering from EVGA or Corsair will leave you disappointed.

Silent Operation

If your goal is to make your PC as silent as possible, it&#;s a good idea to look at a midrange or better model.

As you move up through the product lines, some important differences can be found.

First, by stepping up from an 80 PLUS Bronze to 80 PLUS Gold or higher PSU from either brand, a zero RPM fan mode is made possible on all except Corsair&#;s TX and CX series.

When the PC is idle or under low load, the PSU fan doesn&#;t even spin, which allows for completely silent operation. This is made possible by improved efficiency and reduced heat output.

Beyond 80 PLUS Gold there&#;s Platinum and Titanium. With these models, heat output is further reduced.

Some of these high-end PSU&#;s have larger mm or mm fans to further reduce noise levels.

So, you&#;ve decided noise level is important and you want to go with a more efficient model with a large fan.

Which brand should you go with?

Between comparable models, Corsair&#;s power supplies tend to produce less noise. The noise level of most EVGA models is average or below average.

If you truly want the quietest PSU while keeping the price in check, my top recommendation is the Corsair RM series.

Both Guru3D and TechPowerUp found RM series power supplies to be some of the quietest they&#;ve tested, remaining nearly inaudible under load.


There was a time when comparing power delivery specs truly mattered.

It was often recommended to seek out a multi-rail PSU versus single-rail to split up the load and minimize risk to components.

That&#;s changed since the mid&#;s.

Now most quality power supplies, even at the high end, are single rail. They have reliable Over Current Protection (OCP) to protect your hardware.

Corsair, which sells both single and multi-rail PSU&#;s, even states single rail is just as safe.

So worry not &#; as long as you&#;re meeting the power requirements of your system in watts, you&#;ll be fine with today&#;s single-rail power supplies.

Form Factor

There have been a lot of different standards for PSU&#;s over time, including EPS, TFX, LFX, CFX, and Flex ATX.

Fortunately PC builders really only need to deal with one or two types: ATX and SFX.

ATX, a.k.a. ATX12V, is considered the standard.

Most desktop cases are mid-towers or full towers, where an ATX power supply is the best choice.

This is the most common PSU type so there are lots of options.

ATX power supplies allow space for large fans for quiet, effective cooling.

While the size is fixed at about 85mm high and mm wide, the length of ATX PSU&#;s can vary.

It&#;s important to check the specs for your case to find the maximum size PSU that will fit. Some such as the Corsair HX series are mm or more in length, which may not fit in more compact cases.

Corsair&#;s RM series gets my top recommendation in ATX PSU&#;s for features, efficiency, and very low noise.

SFX, a.k.a. SFX12V, is a small form factor power supply.

These are used in Mini-ITX and SFF cases.

Size is fixed at mm high by mm wide. Certain manufacturers have modified the length (such as SilverStone with SFX-L). Corsair and EVGA stick to a mm length, so they&#;ll fit most any Mini-ITX case.

The trade off to the more compact size is a smaller cooling fan. I recommend an 80 PLUS Gold rated SFX power supply or better to help with efficiency, heat output, and noise.

EVGA&#;s SuperNOVA GM series is my pick in SFX power supplies. Efficiency is excellent, and noise levels are lower than the Corsair SF series.


Whether you go with Corsair or EVGA, you&#;ll get a quality power supply with a great warranty.

In general, EVGA&#;s power supplies are slightly more efficient and compact in size.

On Corsair&#;s side, many of their PSU&#;s including the excellent RM series are some of the quietest on the market. Prices on comparable models are often a bit lower as well.

CORSAIR AX760 Power Supply Cable Installation Guide

Corsair has been in the business of providing PC power supplies since , starting with the "HX Series".

The letters don't really mean anything, so it can be really confusing which Corsair PSU is better than another. 

To further complicate things, a number of the series names get "recycled". Often, with improvements. For example, the HX started as a semi-modular 80 PLUS Standard PSU. It's evolved into an 80 PLUS Bronze, then Silver, then Gold, and then eventually became a fully modular 80 PLUS Platinum PSU.

AX has evolved as well. Once an 80 PLUS Gold, fully modular PSU, it evolved to a Platinum and now an 80 PLUS Titanium power supply.

Some series don't evolve much. RMx, for example, changed platforms, but the performance remained the same.

I put this list together. The PSUs below are ranked from "high end" to "low end".

I'm starting with the PSUs currently in the market:

  • AXi: Titanium efficiency, fully modular, FDB fan with Zero RPM fan mode. All Japanese caps. Rated at 50°C. All analog ICs replaced with MCUs (fully digital). PSU has monitoring capability via LINK or iCUE. Has a very unique bridgeless totem-pole front end with GaN transistors.
  • AX: Titanium efficiency, fully modular, FDB fan with Zero RPM fan mode, analog PSU w/o monitoring. All Japanese caps. Rated at 50°C. Until I say otherwise, all of these PSUs use a LLC resonant front end and DC to DC for the +V and +5V rails.
  • HXi: Platinum efficiency, fully modular, FDB fan with Zero RPM fan mode, analog PSU, but with monitoring. All Japanese caps. Rated at 50°C. Note the "old school" livery. HXi is the oldest PSU in the Corsair line up. Why mess with perfection?
  • HX: Platinum efficiency, fully modular, FDB fan with Zero RPM fan mode, analog PSU w/o monitoring, but a switch to choose between single and multiple +12V rail. All Japanese caps. Rated at 50°C.
  • RMi: Gold efficiency, fully modular, FDB fan with Zero RPM fan mode, analog PSU, but with monitoring. All Japanese caps. Rated at 50°C.
  • RMx: Gold efficiency, fully modular, rifle bearing fan with Zero RPM fan mode. All Japanese caps. Rated at 50°C. From here on down, all of the PSUs are analog without any kind of monitoring or control via Corsair Link or iCUE. The current RMx uses the old generation platform as the new platform maxes out at W.
White RMx
  • RM (new): Gold efficiency, fully modular, rifle bearing fan with Zero RPM fan mode. Supports new Modern Standby Mode and meets new 2% efficiency requirement of 70%. No Japanese caps. Rated at 50°C.
  • CX-F RGB: Based off Vengeance Silver (below). Added RGB lighting reduces efficiency to Bronze. Fully modular, rifle bearing fan. Supports push button RGB, ARGB and iCUE. Japanese primary capacitor. Rated at 40°C.
  • CX-F is also available in a white housing with white sleeved and flat cables.
  • CV & CV Simply nothing more than VS (see next bullet), but with Bronze efficiency. Sleeve bearing fan, no Jap caps, double forward, group regulated 12V and 5V.
  • VS: Regular 80 PLUS efficiency. Non-modular. Sleeve bearing fan. No Japanese caps. Rated at 30°C. Double forward and no DC to DC (group regulated 12V and 5V, mag amp V). #50W units meet ErP efficiency requirements. #00W PSUs do not and are only sold in regions other than the EU.


Corsair SFX PUSs are true SFX form factor and not the "unofficial" SFX-L form factor.  They also come with very short cables because they're made for ITX builds.

Older versions of the series names currently in production (the series has been updated, but they use the same name):

  • AX: Used to be Gold efficiency with DBB fan. The original Gold AX was Corsair's first fully modular Gold PSU.
  • HX: Used to be Silver efficiency and semi-modular. DBB fan.
  • HX: Corsair's original PSU series. Originally 80 PLUS (standard) efficiency. DBB fan.
  • TX: A totally overbuilt for a Bronze PSU with DBB fan. The W was built by Seasonic, the W and W were built by CWT.
  • TX The highest wattage of the early, non-modular TX PSUs. Made by CWT and is 80 PLUS Silver.
  • TXV2: Second generation non-modular TX, now 80 PLUS Bronze efficiency, based off the Seasonic S12II platform.
  • TX-M Bronze: First version of a semi-modular TX-M. 80 PLUS Bronze efficiency. These were made by CWT.
  • RM: Prior to the most recent RM and before the RMx and RMi, It only had a Japanese bulk cap and was only rated at 40°C. It did have an I2C connector that reported +12V rail load and fan speed to Corsair LINK. This was also the first Corsair PSU to use an MCU to incorporate a Zero RPM fan mode.  Prior to this, an analog controller was used in both the AX Gold and second generation GS that was problematic due to using only temperature to determine if the fan should spin or not.

    It should be stated that there was a thermal issue with the early Chicony made W and W units that caused the PSU to shut down even when temperatures were below 40°C when the PSU was mounted in the chassis with the fan down.

  • Vengeance Bronze: 80 PLUS Bronze efficiency. Came in fixed cable and semi-modular versions. Double forward topology. Is literally the same platform as CX-M. Rifle bearing fan w/o Zero RPM fan mode. All Japanese caps. Rated at 40°C. Replaced by Vengeance Silver.
  • Previous generation CX: These 80 PLUS Bronze PSUs were double forward, based off of CWT's DSAIII platform (except W, which was PUQ-B based), but did have DC to DC for the +V and +5V. Rated at only 30°C and has a sleeve bearing fan. Three year warranty.
  • CX with no 80 PLUS: Based of of DSAII. Double forward, group regulated, rated at 30°C and sleeve bearing fan. Three year warranty. There was actually two "versions" (the newer called "V2") but I do not know the difference because they're both based off of the DSAII. The older one did only have a two year warranty.
  • Original CX-M: Essentially modular versions of the original CX Bronze units. So, double forward with DC to DC for +V and +5V.
  • Original VS Series: These were V Only PSUs (would only work with V to V mains). Sleeve bearing fan and a .3mm thick steel housing (context: PSU housings are typically .5mm thick). Sleeve bearing fan. 3 year warranty.

Completely discontinued series (not made any more and series names not reused):
