Chieftec Polaris 850W Power Supply Review

Ripple

The ripple scores provided in our test do seem to back up the results seen in the voltage regulation. With the 3.3V and 5V provided exceptionally excellent scores (in the vast instances, in single whole digits) we do see the 12V rail act a little more excitably. Given that EU regulations allow this to go as high as 50 though, and with the highest score in our results being 33, these are still all entirely within acceptable limits and, overall, show that this power supply has some very decent components within in.
