The Corsair Gaming Series GS800 power supply is the ideal price-performance solution for building or upgrading a Gaming PC. A single +12V rail provides up to 48A of reliable, continuous power for multi-core gaming PCs with multiple graphics cards. The ultra-quiet, dual ball-bearing fan automatically adjusts its speed according to temperature, so it will never intrude on your music and games. Blue LEDs bathe the transparent fan blades in a cool glow. Not feeling blue? You can turn off the lighting with the press of a button.

The red, Ice White, and Electric Blue LED lighting looks amazingly great in the dark. I gave it a solid 4 stars. The only way this component could have been better is if it was a modular PSU. BUT IM REALLY TEMPTED to give this 5 stars.
I bought this from Best Buy, and it was on sale and less expensive than the GS-700, how could I pass it up. Really I couldn't pass it up, The GS-800 replaced my failing power supply sold by a company called Eagle Tech-(don't let low prices entice you) Dont fall for cheap-o deals like I did.
THE GS-800 by Corsair is a great power supply unit backed by a 3yr warranty.
There are many companies that sell PSU's that are complete trash, Corsair is a reputable source though.
Do your home work before shopping for anything. Don't just look at the wattage, look at the side stickers and do your math. Total output, how much is being pushed on a rail and so on. And check the efficiency rating, do not buy anything less than 80+ certified and 100,000 MTBF- Mean Time Between Failures/
And Read, read, read reviews. Google and learn.
* Easy install, of course. The ATX spec is one of the best things to have happened to computers in recent memory, from the standpoint of simplifying build and upgrade cycles.
* 20/24 pin motherboard connector provides flexibility for many generations of boards
* Two 12-v 4-pin connectors for the extra motherboard power and a high-power video card
* Great presentation (durable, attractive finish, blue LED inside, loom-protected cabling)
* Easy-use 4-pin molex connectors (they have curled grips integral to the molex that make separating the molex from its peripheral very easy)
* Nearly perfect voltage regulation (+12V shows +12.175V; +5V shows 5.05V; 3.3V shows 3.296V and the 1.5V bus runs at 1.484V -- all well within tolerances)
* Altogether too many 4-pin molex connectors and too few SATA connectors. I had to buy several converter pigtails to accommodate all of my drives and a power socket on a USB3.0 card.
* The fans are noisy. Compared to the 120mm fans on the case and CPU, the PSU is at least 75% of the fan noise from my rig. I have not noticed an appreciable drop in noise even after removing all magnetic drives from the case (they're now in a separate drive enclosure).
* Fans do not appear to auto-adjust their speed with load; they seem to run at full speed at all times. Note: this may be a more recent specification that wasn't current when I purchased mine in 2009.
I have owned more Corsair memory modules and built them into machines for other people, than I would like to count. They all worked great, and that greatly influenced my decision to get a PSU from Corsair. This PSU has been in constant service since 2009 and has not degraded in any way. I run it over eight hours a day, and it just goes and goes. The load on it has been pretty high for most of its service life, with six hard drives, a 124W four-core CPU, a DVD player, and a couple of internal connections as well (USB3.0 card power, two case fans). Given this excellent performance, I would not hesitate to buy another Corsair PSU, but next time I would absolutely fork over the extra $$ to get a modular power supply and would also look for one with user-selectable fan speeds (e.g. auto).
I purchased this power supply wanting to upgrade from an old 450watt that was more or less obsolete given today's graphics cards. This power supply features a full 48amps on the 12V rail, meaning you can technically run Nvidia's 580 GTX so long as you aren't going for SLI, liquid cooling, etc, etc. I'm not sure if I'd stress it beyond the GTX 570, however. But for someone like me--a casual gamer who mostly does school work on the PC--this is more than adequate. Current system is as follows: AMD Phenom II 965 Black Edition, Corsair GS600, Nvidia 8600GTS (due to be replaced soon with a GTX 570), 8GB G. Skill Rip Jaws, GIGABYTE GA-78LMT-S2P main board, and Hitachi Deskstar 120GB (small but fine for me.) I also have two 120mm fans and an 80mm fans.
Other thoughts: I bought the GS600 at Best Buy for ~$95, and if I remember correctly, the GS700 (700watts) was only ~$114. In retrospect, I should have just spent $20 more for the added comfort. Also, this power supply is NOT modular, which means there is a vomit of cables coming from the thing. Seriously, it's like an overgrown plant in a pot too small. But since I knew I was buying a regular power supply, I won't knock the review of it for that reason. But just beware, you will need to use the zip ties (included) to stuff some of them away.
