NEW RM850x PSU Smell while underload?


Recommended Posts

Hi Guys,

New here, just built an i9 10850K PC, running at 4.8Ghz nothing crazy, I noticed while load testing that the power supply has this odd smell, is this normal for a brand-new power supply? if so how long does this smell last?

it's normal, there's a slight smell of new electronics while it degasses some solvents leftover from manufacturing.


Just finished a build today and got that too from the RM750 ^^


It usually doesn't last long, a few weeks depending on the load, and it fades quickly anyway.

Thanks for the reply, that’s what I thought, because I remember smelling something like that from my older corsair power supply when it was new...

It was an 850w as well, but I remember it was a bit longer but this one is slightly shorter.
