Corsair CX430 V2 receives the "Must Have" award from

“The overall technical analysis highlights that Corsair have paired up with CWT to produce one of the finest budget power supplies ever released. We have tested power supplies at over twice the price with worse regulation and noise suppression than the CX430.”

CX430 V2 wins an award at Jonny Guru

"Corsair has managed to pull off rather successfully something not too many companies can brag about. They've come up with a reliable, cheap, and well performing power supply for everyday systems that don't expect a lot from their power supplies. I do find the thirty degree full power temperature rating to be a bit on the low side, but as you saw here today mine didn't have a problem heating up a little more than that. At this price, it's very hard to do better and very easy to do worse."

Corsair CX430V2 wins an award at TweakTown

"Sometimes it is refreshing to sit back and take a look at non-enthusiast grade hardware. It is simplistic, does exactly what it is meant to do, and is cheap. The CX430V2 is does just that and nothing more. It provides plenty of power, within specifications, for low end systems. It does it without a ton of cables getting in the way or extra connectors that you'll never use. Best of all, it does it at a great price. At $40, the CX430 is a solid buy and well worth considering for any low end system. If you can snag it while there is still a rebate and get it for $27 US, it is a phenomenal buy and you should consider buying four or five of them to have on stock for the next power supply related fixes and low end systems that you're called upon for."

TechPowerUp recommends the CX430 V2

"Corsair's new Builder CX430 V2 power supply really impressed me. At first, when I saw that Corsair rated it for full power only at 30°C, I was troubled and thought that my 50°C hot box would really give it a hard time. However I was dead wrong, the PSU not only worked at over 50°C ambient but performed really well, especially if we take into account that it belongs to the low end category. Voltage regulation was close to 2% for +12V & 5V and 3.3V exceeded 3% only by very little. I have seen much more expensive PSUs with way worse voltage regulation, especially at 3.3V."
