Died after installing win7

Anonymous, Newegg
25 July 2013
  • Summary: I don't dislike Corsair, but it did give me a good scare. Their water cooler and fans have been top notch. Just not this PSU...maybe just got a bad one. A little tramautazing when I just spent almost $2000 and the PC just dies on me because of a defective product.
  • Pros: Fully Modular. Nice packaging.
  • Cons: I put my brand new PC together with the new Haswell cpu. Everything was working up until after the windows 7 install. All of a sudden it stopped working and my PC would not power on anymore. After hours of aggravation thinking my brand new build was fried, I decided to pull apart my other PC's PS...

20 days later.

Heather K., Newegg
7 July 2013
  • Summary: Don't know why my 1st Corsair PSU failed but they certainly didn't live up to the hype for me.
  • Pros: It worked great for the 1st 2 1/2 weeks.
  • Cons: After the 1st 2 1/2 weeks my computer would randomly shut down and would not power back on until I unplugged it. I checked the usual suspects; temps,reseating ram, case power button, etc., and it was only after I installed a spare OCZ 700W PSU that everything worked fine. Ran rime 95 with the OCZ...

DOA

Glory L., Newegg
29 May 2013
  • Summary: NewEgg won't even give me an RMA because I shipped the UPC code off for the rebate. Now I have to deal with Corsair. Hope their customer service is proper.
  • Pros: Looks nice, I even bought the white modular cable kit,
  • Cons: Didn't power on properly. Would turn on for a split second then turn right off. I have jumped the PSU outside of the case with only a fan connected and it did the same thing verifying that it is dead.

  • Pros: 80 plus gold, fully modular. Worked great when it worked.
  • Cons: Died tonight just short of 1 months use. No idea what caused it. Running a 3770k, ASRock Extreme6 Z77, 2 650Ti boost in SLI, Corsair H60, 16GB GSkill Trident, ADATA 256GB SSD, DVD burner and 4 200mm case fans.

Ouch!

Beach Bum, Amazon
13 March 2013
  • Summary: This psu worked for an hour or 2 and then failed and fried my motherboard... Socket 1366 i havent even been able to find a board yet to test to see if it destroyed anything else. Might want to look elsewhere for a psu.

Too bad it doesn't work

Mark H., Newegg
6 February 2013
  • Pros: Should have good specs - was quite efficient. and then became infinitely efficient.
  • Cons: Failed twice, each time in under a week of operation. Now out 25 bucks in shipping costs to have it RMAd. Corsair has been responsive in that department - I guess they get a lot of practice.
