Hi guys,

Recently i bought a Corsair RM850, it does a quietly buzzing noise and like little "sparks" in idle and quiet electrical noise on high load.
I can hear it if i put my ears close of it (10 cm ~) but it's not annoying at a normal distance.

Im worried because it can be a defective PSU or something...

Normal. And it's not a "sparking" that you're hearing. It's more like a rapid buzz.

Ok. Ready. Set. Go!

How does he know it's not 1st gen RM (a terrible PSU that JG praised in forums for years before Corsair got wise and threw out the old platform)?

First off there was the well known problem of overheating on the first batch of Hipro/ Chicony Power Technology made units. Almost every capacitor on the secondary side is Taiwanese Teapo´s and Chinese CapXon´s

That ripple would break my overclock.

But sure, trust the guy who gets paid by Corsair. I'm just a retired nuke ET who went on to get his EE, afterall. If you know what an ETN is, the. You very well know where you are on the knowledge foodchain.

Or just keep giving pats on the back to the guy who loved the original CX (actually he got paid to fake that he loved it).

My goodness, I know I solved at least 1000 threads on just CX/RM on this forum alone between 2011-2015. Those junkers would overheat so fast and get unstable as the dielectric eveporated making the 12v rail go from ------ to ~~~~~~
