2 out of 5 eggsvery bad quality

Pros: silent, modular

Cons: will explode!

Other Thoughts: I bought this expensive psu, because i like quality, but this i had replace two times allready.
First time i heard an explosion, and it was gone.
I had it replaced, and then after a while it would not work sometimes. When i push my pc on, it won't start. Sometimes when i pull the plug it starts... very dissapointed with Corsair.

1 out of 5 eggsjunk

Pros: The name?????

Cons: Ever single one of these that I bought lasted less then a year. I have bought this same unit 3 times due to temporary insanity and none of them work at all. The sad thing is cheaper power supplies that I have bought since then have lasted a whole lot longer then this garbage.

Other Thoughts: Don't buy it because apparently their employees are paid peanuts because they could care less about quality.

5 out of 5 eggsGreat Looking Reliable PSU

Pros: Decided on this PSU for a few ameteurish reasons.

For one I needed a PSU (haha). Also I wanted one that was fully modular because my case design left most of the inside visible hiding extra wires is a pain. Decided to go with Corsair because by chance I had also picked out their RAM, CPU cooler, and SSD for my build. Figured if I was going to be a fanboy I might as well be a total fanboy. :-)

While I can compare specs and pick out parts that will fit toghether I'm no electrician, so I can't really say anything good that's technical about this unit. I can say, however, that the fit and finish are great, and that It's been powering my system almost constantly now for two years (i rarely turn off my PC) and knock on wood has never so much as hiccuped. Can't ask for much more than that.

Cons: None.

Other Thoughts: What's with the fancy bag? When you unbox it the PSU will be in a fancy cloth bag wth a braided drawstring....? Mind blown. The bag did make a great place to dump all the extra screws, cords, etc. left over from my build though.

5 out of 5 eggsBuy the best, get the best.

Pros: Just bought my second one in a year.
These are rock solid, the top tier among power supplies.
Check out HardOCP reviews of this series, they really put a power supply through its paces.
Great warranty, and I've never had to use it.

Cons: Absolutely none.

Other Thoughts: Some may say the price is a con, but do your research!! You won't find a cheaper PSU this reliable, and this is one area you do not want problems with.
