Coil whine on a new EVGA 450 BT

I recently created a new build. I installed a EVGA 450 BT psu into it. No GPU as I'm running a ryzen 2400g. When the pc is turned off, i hear a very high pitched noise, like a dog whistle. The only way I can get it to stop is to use the switch on the pay itself. Anyone else had this issue? Is it a bad PSU?

Maybe it's just bad luck ( failed unit ). Is it in warranty?

This would be from the +5VSB transformer, as it remains active even when the PC is shut down and PSU is still turned on. It isn’t going to kill the PSU. Coil whine isn’t too uncommon, even with high quality power supplies.

I’ve read you can leave some USB flash drives in your computer which may solve the issue.

Otherwise you could RMA it.

The PSU isn’t really good, as it’s group regulated, only rated for 30°C, and missing some important protections.

Any you recommend I replace it with for a similar budget? I thought any EVGA 80+ bronze one would be decent at least..

No, because you don’t need good quality, performance, protections, fan, cables, warranty, etc to achieve decent efficiency. And companies can lie about those efficiency badges.

Did you try leaving a couple flash drives plugged in?

Budget oriented, yet well valued units can include the Corsair CXM (2015), Corsair CX (2017), Cooler Master MasterWatt, be Quiet! Pure Power 10 (400w+), or Xilence Performance A+, depending where you are buying from.

Recommend asking EVGA support ... or you can also ask on "EVGA Power Supplies" forum:
