CORSAIR Builder Series CX430 CMPSU-430CX 430W Power Supply

100% Positive Reviews
Rated #13 in Power Supplies


Pros: Sleeving, price, look

Cons: Not modular, a small noise can be heard whilst it is switched off

I bought this PSU as I was on a budget.
The PSU performs as expected, and is able to provide enough power for my rig - which includes a i3-3225, a Xonar D1 soundcard and a Gigabyte mATX motherboard.

My only complaint is relating tot he noise of the PSU when it is OFF.
It is extremely hard to hear, however if your ear is pressed upon the PSU, when it is off, from outside of the case, you can hear an electric type of noise (unlike some people who have previously reviewed this PSU on the internet, making wild claims about its noise, it isn't noticeable unless you're batman)

The other remark would be the fact that it isn't modular, meaning there are huge amounts of wires that won't ever be used, but yet are left floating about in the case. This isn't an issue as this is a budget PSU, but something that definitely should be taken into account when building a PC.


Pros: Lots of cables, high quality finish, LONG cables that are easy to manage, single rail, super quite

Cons: Non modular, you can see all of the cable through the sleeving

When I was looking for a low power, high quality power supply, the Corsair CX430 v2 certainly was a head turner for the price. It is cooled by a ultra quite 120mm fan that I can't even hear over my hard drive. The really long cables come pre-sleeved but the sleeving materials used could be higher quality, these feel like they will rip with the pinch of your fingers. The stickers on this unit are really nice, It has a label on each side and depending on which direction you have the fan pointed intaking air there is a corresponding sticker so you don't end up with an upside down label. But the info label is visible when you have the fan intaking air from the bottom of your case, it really looks bad if you are OCD about how your system looks. The single rail advantage is nice since you don't have to worry about how much power you need to equal out on each rail, it all goes to one rail. Corsair power supplies are well known for their efficiency, most of them are certified 80 Plus like the CX430. At 80% efficiency, it delivers 430 watts of CONTINUOUS power to my system. So that's a guaranteed 430 watts and still even more hidden power. Even their high powered units such as the HX950 and the GS800 are certified to lower your energy bill and increase your power output safely compared to low end generic units.

Overall, Corsair customer service is DA BOMB. The sleeving could be better on these CX units, but for the price you pay it's well worth it. All fancies aside this is a great unit, if you are looking for a quality power supply under $40 and you don't have the most power hungry system in the world, get a Corsair CX430.
