 Very good as far as I can tell August 31, 2010
Martin (Cleveland)
From all my research on getting a powerful and reliable psu this one stands up there in the top ranks. I have had it for a week or so and it is doing it's job. I know it's living up to it's rating too because my system no longer shuts off under load when playing games using an nvidia gts250.
I am very serious about using as little energy as possible whether it's gas, electricity, etc., but I love playing the latest games on my pc---- I'm sure many of you do too so at least get an efficient psu. I feel at least somewhat better running an 80 plus psu in my system knowing that less energy is just being wasted as heat.
On the same "green" environmental tangent--- change your light bulbs to high efficiency CFL bulbs :) (or led)
P.S. If a psu could be "sexy" then this one definitely is sexy. It is super well built, has black meshing around the cables, and even comes in a sexy velvet pouch! At least by the looks it screams high quality. Corsair products always seem to do very well for me and others give them high ratings too. I definitely recommend their products. No flashy led's or lights in the psu necessary. Just black, industrial efficiency!
Good product. (Reviewed August 31, 2010)
The best August 31, 2010
M. Waddington (USA)
Of the many computer parts and components I've bought so far, this appears to be the best. Top of the line quality appearance,wins awards for efficiency, and has a moderate price. All the cables are simple and bound together, and there is more than enough for everything I need. It is powering my old ATX motherboard just fine, along with my new GeForce 460 GTX, but I know I can continue to use it as I upgrade my motherboard later (has forward and backward compatibility.
Highly recommended.
 Product Returned July 26, 2010
T. Newman (MPLS, MN USA)
Product quality problem; unit returned because of a defective internal fan. The PS measured less efficient than a 68 percent efficient unit being replaced, but that could have been related to the fan defect. No immediate plan to order a replacement.
Great and reliable power supply July 23, 2010
Slick Shopper (Huntington, NY United States)
If you're a power user like me, the mark of a good power supply is that when it does finally wear out it doesn't take your motherboard with it.
When my old power supply finally went, I chose this one. I was very happy with the quality of it and how well thought out the design was. It has excellent reviews and good strong output. It's everything a high-quality power supply should be.
((For those who are curious, my old power supply was a Thermaltake. It lasted forever and protected my motherboard when it did go. I have nothing bad to say about it. But after comparing the two I would buy the Corsair in the future, simply because it seems slightly better designed)).
I also appreciate the rating that Corsair gives their supplies. They give a much truer rating for their power supplies. This 550 is equivalent to the 750 rating on a cheap power supply. So don't be fooled by cheaper brands. You will almost certainly never need more power than this supplies, even in many dual graphic card setups.
This also had every power connection you might need for motherboards and 1 or 2 graphics cards as of July, 2010.
excellent performance July 22, 2010

power supply has a rugged durable look, had it for two months with no problems, and the quality of the power supply is far superior to similar 650 watts i have seen-the difference can be seen from the packaging itself.
