This review was originally published on May 21st, 2011 but was accidently removed so here it is with updated technology and methods for benchmarking.

 

When you are building your own PC one of the most important components to it is of course your power supply. One company I have trusted for a long time has been Corsair for making products I can depend on, and if in the unlikely event something happens, one of the best customer support teams I have come into contact with.

This review will be different than what you normally see, and is broken into 2 categories: Durability, and finally Cost vs. Efficiency.

 

Durability

One very key component to any custom built PC is to ensure everything is rugged, and can last as long as possible to keep your wallet in check. Let’s face it, nobody wants to drop $800+ on a custom built PC and have it turn to junk because a PSU –or something else- fails.

Let me put this into hindsight for you, I completely tortured the GS800 Gaming PSU (sorry Corsair), and I beat it to hell. The point is I wanted to make sure this PSU could perform under the most extreme conditions (this was done after the initial review / benchmarking), and first off was the weather test.

Michigan weather is torturous, both when it gets extremely hot out, and when it gets very cold out. So I ran a few different tests to ensure voltages where up to where they needed to be in order for my custom built PC to function correctly. So here we go, but first I will introduce you to my setup rig:

Motherboard Gigabyte GA890FXA-UD5
Processor AMD Phenom II  840 w/ Corsair H70 Liquid Cooling
Graphic Card(s) Crossfire Enabled Vistiontek HD5770s
HDD OCZ Technology Vertex3  (OS)OCZ Technology Revodrive

Western Digital Velociraptor

Operating System Windows 7 Home Premium 64-bit
Memory Corsair Vengeance 1600Hz 8GB kit
Additional Hardware Keyboard: SteelSeries SHIFTMouse: SteelSeries Kinzu V2

D-Link DWA-552 Xtreme Wireless N adapter

Western Digital 500GB External HDD

 

Case In-WIN BUC w/ 5 120mm fans

This setup is by no means a be-all-end-all, but I wanted the maximum draw I could get (with what I was comfortable with and what I could fit).

The most important thing was the installation of Windows 7; it was a fresh install, then stripped bare to just the bare minimum. At this point, various games where installed via Steam and Origin to map out the appropriate voltages, and really push things to the limit.

As promised, the weather test is unique in itself, as I have never seen anyone do it before. However, this is an appropriate benchmarking method because extreme cold and hot conditions can put various levels of stress on anything your PC has to offer. Think of it this way, it is kind of like your car battery –except not a battery- and when it hits a rather cold condition it is harder for it to gather the appropriate power in order to start your vehicle. The Corsair GS800 is somewhat the say when faced with a similar situation as it adds –as I said- various amounts of stress.

So here is what I did: I went outside on one of the coldest days we had this past winter (around -3*F) , and then took it out on other days to ensure proper testing. I cleared a path in the snow, and setup a little gaming “workstation”, opened the case to expose it to the elements (it was a clear day) and then began testing. Between each test, I left the PC alone for over 24 hours at a time (inside), and when it came time to test it I brought it back outside and let it sit for an hour before startup.

Degrees (*F) Minimum Wattage Maximum Wattage
-3 122w 346w
18 128w 347w
22 133w 347w
70 144w 378w
88 143w 377w

 

To me for some reason all these numbers looked weird to me, so I tested it time and time again and kept coming up with the same exact numbers (within ~2w). To be honest I was expecting a major influx as I used to see on various other reviews. All the same, I am rather impressed with how well it performed when being put through such a non-traditional benchmarking test.

The final benchmark I wanted to include was the very traditional “how long does it last” test. I had received this PSU from Corsair on May 4th, 2011 and it has been in my gaming PC since. It has ran at a consistent level since I have had it with various changes made to hardware including upgrades. The best part is that it is still going strong as it was the day I got it.

 

Cost vs. Efficiency

This part of the review is mainly geared to showcase how efficient it is vs. the cost of other manufacturers. All prices are found via Newegg.

Manufacturer and Model Cost Efficiency
Corsair GS800 $124.99 80+
Rosewill LIGHTNING-800 $149.99 80+ GOLD
Mushkin MKNPSJL800 $119.99 80+ SILVER
TopPower TOP-800WB $91.99 80+ BRONZE
XigmaTek NRP-MC802 $129.95 80+ BRONZE
CoolMax ZU800B $95.99 80+ BRONZE
Thermaltake TR-800P $129.99 80+ BRONZE
Cooler Master RS800-80GAD3-US $159.99 80+ GOLD

 

If you look at the above table, compared to the other prices / watt / efficiency going with the Corsair GS800 power supply is the right thing to do. Not only is it a great price, but it is a brand name you can trust, and it is 80+ certified which helps the environment.

So in conclusion the Corsair GS800 power supply is a great buy, and it very reliable for all of your needs. It is great for your average build and can support your upgrades you will make in the future. For $124.99 on Newegg that is a great deal for any builder!
