Hey! I have a strange issue with my new pc. The system works like it should, from the first boot forward, except theres a electric ticking coming from the PSU area. The sound is there even when the pc is turned off so its not a fan. Ive tried with 3 brand new power supplys and after a couple of hours they all developed the same issue. 2 Corsair VS650 and EVGA supernova g2. They tested the first corsair at the store aswell and they could reproduce the ticking. It began instantly after they turned the power switch on the unit even tho it was under no load on a test setup. Im not using my pc now since Im worried that I will fry other components. It doesnt sound like coil whine either. The sound is not normal for sure. Could I have a faulty motherboard which somehow damages the units? Or could there be voltage fluctuation or something in the mains power. Its driving me crazy!
