Corsair CX430 V2 430W

Corsair was using Seasonic units for the majority of their products, but most of their cheaper offerings are now manufactured by CWT. The CX430 V2 is the lowest-end unit from Corsair, which still has enough quality to satisfy the customers. It comes in matt black and has a large Corsair logo on the fan grille. The back is perforated with hexagonal-shaped openings and a small power switch can be found above the power input.

The contents of the package are what you'd expect. You get the required four screws and power cord, naturally, along with some cable ties, a user manual with product data and safety references. Corsair prefers a large single-rail 12V design, rated at 28A (336W). The reason for the high rating of the 12V rail is the high power consumption of CPUs and GPUs.The small rails are rated at 20A each with a combined output of 120W; that's comparatively weak compared to some older PSUs, but since modern PCs usually don't need much from the low voltage rails, this will hardly be a problem.

A 120mm Yate Loon fan cools these units. It has a ball bearing and seven sharp-edged fan blades. A plastic guard blocks part of the intake area to help direct airflow.

Cables and Connectors

Connector type (length)

Main 1x 24-pin (45cm) fixed
ATX12V/EPS12V 1x 4+4-pin (50cm) fixed
PCIe 1x 6/8-pin (50cm) fixed
Peripheral 3x SATA (ca. 50, 65, 80cm) fixed
3x SATA (ca. 50, 65, 80cm) fixed
3x HDD, 1x FDD (ca. 50, 65, 80, 95cm) fixed

The inside reveals a typical CWT design with three heatsinks, two for the primary side and the third for the secondary side. Three of the filtering caps are attached to the other side of the AC jack. The internal layout is pretty typical using a two-transistor forward converter, with a minimal number of components in the transient filtering. The primary cap is made by Samxon--just like the secondary ones. They are a slightly lower end vendor CWT uses for these units.

    I have bought two of these on sale from newegg for about $17 after $20 rebate. For $17 these are great power supplies. Reply

    I agree. I purchased one of these on a similar deal at NewEgg. They ended up sending the 600w version of the PS so I got an even better deal on it but it's been a good inexpensive power supply. I do agree that it definitely isn't silent when the fan really spins up but it's not horrible either.

    Newegg happens to have this PS for 25$ after 20$ mail in rebate right now.

    You got a competent 600W PSU for 17 bucks? You lucky SoB!

    I hope it found a good home in a nice machine.

    I've had a Corsair HX 620 for about 6 years now and it has NEVER skipped a beat, "only" got 1 year left on the warranty, I've recently relegated it to another machine and grabbed a Corsair HX 850.

    The thing with Corsair PSU's though is that you always have peace of mind as all the PSU's they offer are good.

    None of these power supplies in the article are CHEAP - save perhaps the one Sinan that almost nobody likely recognizes.

    These PS are low wattage near top of the line PS.

    I'm not certain how the anand reviewer got that so wrong.

    Whatever - it's one word but still... it's the concept, and being correct about what is spewing forth that counts.

    These are EXPENSIVE power supplies.

    I can show the never joe blows here some cheap power supplies - or the article writer - since the elitist smell of self aggrandization is all about...

    I can't make it on 100K a year either...

    uh... pipe down over there, guy. the most expensive psu is 55 dollars. most are around 30-40. what's cheap? 10 bucks? if you need a 10 dollar psu maybe you should reconsider your choice of hobbies. Reply

    Totally agree. Tom's wouldn't recommend low quality (cheap!) PSU's for two very good reasons:

    For one, you save money by spending more, especially if you leave your PC on all the time. Better efficiency at idle means you pollute less, and spend less money on energy.

    Secondly, if your PSU dies, your motherboard can go too. Who wants to waste money and have the hassle of that? Buy quality. At least if your motherboard perishes it probably isn't your fault (as long as you pay attention to ESD. Also, although you can buy better grade motherboards too by doing your research, but you will still get the one that dies the second day you use it now and then).

    If you want to buy an exploding toaster to power your PC have at it. That's one less ignorant poster online.

    You get what you pay for. I bought two of the V2 units - both exhibited coil whine across multiple builds and one failed to run reliably (standby power issues.) One I gave away and one is sitting on my parts shelf. It's anecdotal evidence but still enough to make me avoid them.

    Antec's EarthWatts 380D has been my default choice for awhile now, but I'll have to give some of these a shot.

    I don't think "you get what you pay for" always applies, because I bought a Seasonic X650 gold a while back, which is a fairly expensive and highly rated unit, and I get coil whine. It happens. Reply
