S12iii 450w vs corsair cx 550

[hello_there_123]

Which one would be better suited for a system that consumes way under 450w, like most single cpu+gpu systems. I heard that the s12iii has been improved a lot and features better topology, and protections esp dc-dc instead of group reg but i am concerned about the noise and the overall quality.

I'd go with the Corsair. Hard to argue with their reputation.

I'd go with the Seasonic. Hard to argue with their reputation.

So you don't care if the Protection is lacking, the PSU not that great and might not even hold a candle to the competition, as long as the right label is on the PSU??

The S12-3 doesn't seem to have OCP on minor rails. That#s a major disadvantage.

And there aren't many good Reviews. The 500W Version in the Test I've seen had rather high ripple.

So either be quiet Pure Power 11 or not the Seasonic.

Where did you find that it's DC-DC?

That's not DC-DC, that's dual Mag Amp for the S12-3.

The difference:
one is Analogue, the other digital.

One requires load, the other does not.
