HI all, I finished my build about 2 weeks ago and I've been hearing electricity noise from it every time.

During startup and on lite use you hear a lot of electricity 'sizzle' noise, audio.

I swapped out my intel stock with a mugen 5 and the problem is still there.

When under CPU stress, the noise starts to go away but when going back to near idle or light use, it comes back

I'm wondering if you guys can give some ideas o nthe cause or some fixes, thank you.


Heres my specs:
Asrock Z490 ITX ac
i5 10400
scythe Mugen 5
ROG RX 580
team t force 16 gb ram
Corsair SF600 Platinum

I, at least, don't know what else to tell you beyond it being VRM switching frequency.

Maybe the VRMs on that board aren't that good :unsure:
