Would not buy again 3/18/2015 6:18:06 PM

Pros: Non-doa, quiet fan, paint is nice

Cons: After buying a CMPSU-400CX before I expected a lot more out of this supply, what I found was Samxon caps, a sleeve bearing fan, and generally much poorer build quality than I was accustomed to from corsair. The unit died 2 months after the warranty ended from buldging Samxon capacitors, and even if that were not the case I still would have voided the warranty by opening the unit to look at it

Overall Review: Although it could be said the build quality was better than a bargain basement power supply, it was not what I was looking for after all the other corsair power supplies I bought up to that point. At least it didn't take anything out when it died. Best advice I can give anyone is research the exact power supply you want to buy, as like this one the OEM was different than whoever made the 400cx, and the quality suffered despite the name badge on the thing.

kicked a&* for 4 years 2/7/2015 9:09:31 AM

Pros: This thing has ran everything from my original build to my newest setup running a HD 7970 and two SSD's along with a lot of other devises. In 4 years it has never failed. I'm only replacing it because im going to SLI two of these beefy cards.

Cons: none

3.5 years later... 5/22/2014 10:09:52 PM

Pros: This guy had a good life. For 3.5, it sat in my server 24/7 without issue.

Cons: It's only 430W. I've upgraded my motherboard and this PSU just can't handle the work. Time to replace.

Can't complain 6/10/2013 7:11:35 AM

Pros: - It works
- Hasn't blown up

Cons: I sometimes notice a high pitched whining that seems to be coming from this power supply. I've heard that other corsair CX series power supplies have been known to do this. Not really a con though, just maybe a bit concerning to me.

AWESOME! 2/23/2012 1:29:52 AM

Comments: I have had this running on many different rigs over the last year and it has been flawless. It ran my 2600K, HD 5870 with ease. Barely got warm under heavy stress tests.

Currently on my AMD FX-8120 8-core overclocked to 4.450GHz with a 7750 and it goes over 330Watts full load according to my power meter I bought recently. It barely gets warm as well.

Full load is Kromtor (Furmark) for video and Prime95 together for full hour minimum several dozen times and overnight a couple of times.

There is a newer version V2 of this and it's suppose to be even better for the same price.
