Still on it

Pros: I've been running this on a custom build since 2011. Always pumps out the power I need, 38A on +12v rail is beast mode for most builds. ex 750ti run max load at 100A and running 456A on PSU.

Cons: It doesn't summon repairbot

Other Thoughts: I'm not a corsair fan boy...this thing is just a beast. 5th gen custom build and this PSU has run 4 years vs a standard of 2.5 in my experience. I'm expanding and going to roll with this until it fails me.

24-pin cable doesn't fit in MOBO

Pros: NONE

Cons: 24 pin atx-power cable doesn't fit in the mobo. Becareful, this is a common problem with the CX series.

Other Thoughts: Corsair makes some pretty good parts, but I do not reccomend buying this series of PSUs.

Lived only as long as its warranty

Pros: Great PSU, Simple did the job well while it was in the land of the living.

Cons: Short CPU 4/4 power wire.
Died after roughly 3 years of powering a Pentium D and a 9800gtx and took the 9800 with it...

Other Thoughts: I can't really complain that it died shortly after its warranty was up... But I honestly expected better from Corsair. There wasn't even that much draw on it.

I would not recommend the Corsair CX series to anyone. 3 years or not a PSU should be the most dependable part in your computer.

My advice, spend a couple extra bucks and get a SeaSonic. Even if its for a cheap machine.

Several bad Corsair CPUs in a row

Pros: none

Cons: I have a total tdp system of about 250 watts. This power supply couldn't handle it from day one. There just isnt enough power for the most basic core 2 duo rig. Also, the high pitched humming noise when its turned off is unbearable.

Lasted about a year

Not very happy

Comments: Since they have stated how behind they are in their replacement warranty service, I worry that their power supplies are commonly failing and that this may happen to me again. :(
