PSU / Power Supplies Reviews

Cougar GX Series 900W Power Supply Review
By Paul Johnson September 21, 2011
Reading the feature set of this new power supply we see that it hits on many of the things we like in a PSU; high efficiency, high performance at 50C, good cable management, and Japanese capacitors. Of course having a great marketing sheet and having a great PSU are different things. We find out if this cougar pounces.
Why 80 PLUS® is Irrelevant to You When Buying a PSU
By Paul Johnson September 15, 2011
A HardOCP editorial about the 80 Plus® program and how it is changing the computer power supplies you are buying. Is this good, bad, or ugly, and should you care? Did you know that you paid for that 80Plus rating on your shiny new PSU? Certainly PSU efficiency is a great thing, but what about the rating system?
Athena Atlas 800 Power Supply Review
By Paul Johnson September 12, 2011
This is not our normal PSU review, in fact it is likely to get much more attention from IT professionals than computer hardware enthusiasts. Two 800 watt power supplies all in the space of one PS2-sized desktop PSU. Is there any way that Athena can be supplying a high quality power output from such a small space?
Enermax Platimax 1200W Power Supply Review
By Paul Johnson September 06, 2011
Enermax is one of our long time favorite brands when it comes to PSUs. Enermax has proved over and over again that it is one of the world's premier PSU builders. Today it steps into a realm that is tough to compete in and in fact has not ever been seen by any other PSU builders as of yet. 1200 watts that is 80 Plus Platinum certified.
Topower 1000W Gold Power Supply Review
By Paul Johnson August 30, 2011
Topower steps into the big leagues with its new 1000 watt "Gold" power supply that is part of its Nano Series PSUs. You probably realize from the "1000W" and "Gold" in the name that Topower thinks very highly of its new non-modular beast. We put it to the test and see if it is gold as Topower would have you believe.
Corsair Enthusiast Series TX850 V2 PSU Review
By Paul Johnson August 29, 2011
70 amps of power, tight voltage regulation, low ripple and noise, thermally controlled fan speed, all topped off with 80 Plus Bronze efficiency. All of this in a "value-oriented" power supply from Corsair, or least that is what Corsair is telling us. We put it to the test and find out if "value-oriented" is where you want to invest your hard earned PSU budget.
The Black Art of Dual PSUs in Your Enthusiast PC
By Paul Johnson August 24, 2011
Putting two powers supplies in your computer has been a recurring subject in our forums for years. While the physical process of making that happen is not exactly rocket science, it still can be daunting for some users. Today we show you a few products that make it easy for anyone to double up on the power should your wattage needs increase.
Thermaltake Toughpower 1350W Power Supply Review
By Paul Johnson August 15, 2011
Thermaltake is back on our test benches and back with some very big iron. Thermaltake made some of the "biggest and baddest" computer power supplies years ago and we are about to find out if the company does once again. However this Toughpower is well above a kilowatt and surely will have a limited appeal, but also surely attract a lot of attention.
VisionTek 700W Power Supply Review
By Paul Johnson July 25, 2011
VisionTek, once know solely by enthusiasts for its Made-in-the-USA video cards, now just a former shell of itself, has been quietly diversifying its business to help its bottom line. Today we look at a 700 watt VisionTek power supply that we saw being sold on special and decided to pick one up for ourselves and put it in the grinder. Quality buy or pig sty?
In Win Commander II 1200W Power Supply Review
By Paul Johnson July 19, 2011
Big wattage in a big package is what In Win is touting. When you get to 1.2 kilowatts, you are talking about serious power and you will want a very good unit in your chassis when you are talking about actually using what one of these PSU can put out. We put the new 1200W Commander II to the test. Pass or Fail?
LEPA B Series 850W Power Supply Review
By Paul Johnson June 20, 2011
For those of you that do not know, LEPA is what we would call Enermax' low cost "house brand" of PSU. No, it specifications are not up to those of most worthy Enermax units, but then again, neither is the price. How does LEPA do with its second unit reviewed here at HardOCP?
Enermax MaxRevo 1350W Power Supply Review
By Paul Johnson May 23, 2011
Enermax has long been a favorite of ours when it comes to power supplies for heavy hitter enthusiasts pushing huge system wattage loads. Today it is launching a new flagship product that comes to up touting a huge 1350 watt usage rating. Does Enermax continue its top shelf legacy?
