Corsair CX430V2 430 Watt Power Supply Review

Test Results


Our load tests utilize a couple of FAST ATE active load testers and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe and a power consumption meter. You can read more about our standard testing approach here.


The tests performed are based around six conceivable setups that are out there and progressively load down the PSU up to the power supply's limits or 1000W, whichever comes first. Since our test equipment's limits are greater than that of the Corsair CX430V2 430W PSU, we can test it to the maximum.






Taking a look at the voltage regulation tests, we see that the power supply is far from perfect. That's quite ok in this case and it simply isn't meant to power an enthusiast rig where the extra voltage regulation will give you an extra 150 MHz overclock. Instead, the CX430V2 produces solid numbers from start to finish. Both the 12V and 5V rails manage to stay within 2% regulation. The 3.3V rail doesn't quite do as well, but still stays within 4%. At no time did the CX430V2 even come close to being out of specification.


DC output quality was overall quite well for the CX430V2. Test 1 showed a rather low reading of 9mV peak to peak and this increased as the load increased. Under full load we saw a maximum of 24mV of ripple on the scope. You simply couldn't ask for anything better from the CX430V2.


Perhaps the one area that the CX430V2 struggles a bit is in the efficiency category. The power supply is 80Plus certified and that is it, not even a Bronze rating here. That means that the power supply just has to stay at or above 80% efficiency through all of the tests. While the power supply did so, it would have been nice to see more efficiency out of the unit.



Final Thoughts


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.
