3 out of 5 eggsWorked great, until The Squeal

Pros: Nice stable supply from reputable company.

Cons: Started to squeal last year and has only gotten worse :( Too bad, I had great hopes for this unit. Gave it a star for number of years it lasted :)

5 out of 5 eggsGood PSU for non-gamer

Pros: 400 Watts is enough for a budget build. This is a quality PSU.

Cons: $55 seems a little high for 400 watts. But for good quality, I guess we shouldn't complain... No eggs taken off!

Other Thoughts: This PSU has been in a budget build PC since 2010. It is bottom mounted in the case. It had soda pop spilled down through it. A fuse blew. I am an electronic tech. so was able to repair it. It is still working, but I'm sure the warranty is shot.

5 out of 5 eggsDied but it was not its fault

Pros: Great PSU for the price, great/clean dc current, PFC, Everything i needed for the media computer/house file server i was building

Cons: after a whole 1 1/2 years of great and problem free service, i got some parts to upgrade the server and i knew that it was going to be too much for this 400w psu to handle.

Other Thoughts: Went from a (Pentium)E2200, 3X 1TB WD hd and a 3870 to a C2Q Q6600, 2 more ram sticks, a GTX 460 and another harddrive! I just knew that its a quality product and will not fry my equipment when it gave up. And it actually still works under light load for some things, but its only giving 11.8V on the 12v rail which was the one that was overloaded badly. Upgraded to a Seasonic psu, which is who actually makes these power supplies for corsair anyway!

1 out of 5 eggsI wouldent reccomend it.

Pros: It turn on?

Cons: Bought it back in 2010/11, from the first day of using it, it made a horrible squealing sound, it sounded like a electronic vibrating noise, (best way I can describe it). I still use it to this day tho, it dosent bother me so much since I use headphones. I just thought I'd share this in case anyone was interested in buying it. Woulda RMA'd it earlier but lost the box, just recently came upon it again so Will hope to have them replace it..

Also, I've read on fourms that other people have the same problem with this PSU, so I would stay away from it.

Manufacturer Response:

Dear Dre,

We're sorry to hear about your power supply making odd noises. If you haven't already, filled out an RMA form on our Support page and we'll be more than happy to replace it for you.

Thank you,
Corsair Customer Support

5 out of 5 eggsReliable PSU

Pros: Has given me no issues for almost 2 years. Components are high quality and the cables are wrapped to keep things neat inside the case. Plenty of connections for my purposes, too.

Cons: None.

Other Thoughts: I initially bought a Rosewill PSU and it fried several components. I spent a little more and bought one of these. 2 years later, everything is running smoothly.

Big thumbs down to Rosewill. Big thumbs up to Corsair.

5 out of 5 eggsStill going!

Pros: Good, cheap replacement for one that failed by another company.

5 out of 5 eggsGreat little supply

Pros: - Inexpensive
- Reliable
- Quiet

Cons: - Not available anymore? This makes me sad.

Other Thoughts: I bought this a little while ago for a build that never went through. I finally got a chance to use it in a build and it's awesome. Not trying to power Crossfire 7970s with an i7 3960X, but for a budget supply meant to power a nice, efficient PC, it's pretty excellent.

3 out of 5 eggsWorked for an hour

Pros: Nice looking - great price after Rebate

Cons: Died after less than an hour's use. Now I get to see what the Warranty is worth.
