Depends on the underlying PSU they use.
Years ago I swore I'd never buy a Corsair PSU because they were really bad when they first started selling them. But now I run a Corsair RM650x, a series I picked specifically because it's very quiet and couldn't find any comparable models from other brands that didn't cost a fortune. It actually replaced a Seasonic which I hated because it was incredibly loud.
I thought they were about even. No?Seasonic probably takes the crown with their platinum series. But the high end corsair units still last a decade.
Which series?lots of people grumbling about corsair coil whine too...
hx1000i is one. there are a couple threads here and in one the op says there are a bunch of people on corsairs forum complaining about it. its not loudness its coil whine though, that buzzy screechy noise under load.Which series?
The Rmx series is rated highly and although not silent, it's fairly quiet. The rm550x and rm650x were recorded at 14db approx. by Tom's Hardware.
That's not bad, right?
Seasonic Focus Gold and Platinum are pretty good too.
Channel Well AFAIK.
Like many of the replies stated, it depends on the particular unit. The RMx/RMi and higher lines are good. But the CX line? Not for the IMHO overspecced higher-wattage models in that line (and I am talking about the proverbial "750W" budget model that performs more like a mediocre 600W PSU). The lower-wattage members of that budget line are fine for basic builds (that is, not equipped with a CPU that has more than 6 cores/12 threads, not equipped with any unlocked CPU or unlockable motherboard, not equipped with a discrete GPU above a plain GTX 1650 GDDR6 edition - in other words, I am talking about an Intel i5-10400 system with a B460 or H470 motherboard and not much, if any, of a GPU).
