I might have been doing something wrong so would love some points. Before replying to me just "RMA", I live in Turkey and sellers are not nice as they used to be.
I bought an Everest-brand 250W (peak 300W) PSU just for a i3 8100 system with an iTX MoBo, 1 ram and 1 2.5'' SSHD, 2 fans. So it's practically a kiosk system that shall pose no PSU threat.
I noticed PSU makes a whine sound while PC is off. I turned on deep sleep and sound stayed but lower. Also, no USB ports power anything while PC is off.
At the end, after 8 hours of use and 2 hours of idling, I removed all connections and powered on only the PSU. The whining was there. I googled all around but could not exactly find an answer to this:
Can it be considered normal for a healthy PSU to whine while turned on without being connected to anything else?
Btw even though the product looked brand new -for me-, they wrote somewhere in very small letters: "P201401". So, well yes it's a brand new "old" PSU (my mistake, live&learn >.<). Thanks, everyone.
