Corsair Builder CX430 V2 430 W Review - Page 1/8 | techPowerUpCorsair's new Builder CX430 V2 powersupply 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. On top of that efficiency was decent overall and high enough at loads below 90W; ripple/noise suppression was excellent, too. Even in the very tough Advanced Transient Response tests the PSU managed its +12V and +5V rails very well. The bad performance of 3.3V in the same tests couldn't spoil the excellent impression this unit had already made.
For users on a limited budget and for office or download PCs this PSU is ideal. Its price, taking into account the performance levels it offers, is a steal. On top of that it comes with fully sleeved cables and is backed by a three year warranty. If only it had two PCIe connectors and two more peripheral ones. Especially the single 6+2 pin PCIe connector looks odd and significantly restricts the usability of the unit.
Corsair CX430 V2 Power Supply Review | Hardware SecretsThe Corsair CX430 V2 proved to be an outstanding product, possibly the power supply with the best cost/benefit ratio we’ve ever seen. Costing only USD 45 (USD 35 after sending a mail-in rebate card), it provides efficiency between 81.2% and 85.4%, which is comparable to several 80 Plus Bronze units we’ve reviewed. It also has a very good voltage regulation and ultra-low noise and ripple levels. The cable configuration is compatible with an entry-level 430 W unit, and users that need more cables will have to buy a different product.

The only differences between the CX430 V2 and the original CX430 are the active PFC transistors and the +12 V rectifiers, which were upgraded. These changes improved efficiency considerably. (The original CX430 presented efficiency between 79.4% and 84.1%.)
It is impossible to not get excited with a product that is inexpensive and provides the same performance level of more expensive units.
