Did you notice any coil whine with this PSU? I bought a Corsair Rm850x and it has a slight steam whistle type noise even while idle.
coil whine is super weird, it depends on your hardware configuration
Oops I meant the Rm850e.
Is coil whine generally common amongst most PSUs? I noticed that the capacitors on the Rm850e are non-japanese, could that be a contributing factor?
Thank you
in general for me, since I have lots of test systems, coil whine has to do mostly with the graphics card in use and the current use (e.g. game menu or desktop)
