I really dont like Corsair PSU's, ive had two, one that was DOA and the other would not power up after a week, so i got a club3d instead which is working well. Thinking i was unlucky i got a corsair for my friend chris, which made a ridiculous buzzing, cracking noise, so they replaced it with another corsair and the fan failed on it and started overheating, so he got a club3d, which is working fine. Four for four, 100 percent failure rate corsair PSU's for me lol.
