Question Pc won’t boot Psu making weird noises when plugged into motherboard

[TheAvergers]

PC Won’t boot and EZ indicator lights don’t come on

New PC won’t turn on after RMAing half the parts

I first tried to assemble this pc about a month ago now and I haven’t been able to get it to turn on once. I’ve sent it to the local pc repair place twice now and I’ve had the mobo and cpu RMAed from NewEgg and back and it still is giving me the same issues. Today was my last attempt at rebuilding it and now the Psu is making a weird wurring sound. The only sign of life at all consistently between the tries is that the flash bios light comes on properly when the button is pressed.

Update: I did the paper clip test and the Psu fans come on without the sound and test benched the mobo and the problem still persists

Specs:
Storage: WD_BLACK 1TB SN770 NVMe SSD
moboro Z690-A Wifi
Cpu: Intel 12600k
Ram vengeance ddr5 2x16
Cpu cooler: fuma 3
Case: Corsair 4000D Airflow
GPU: 3060 ti

*the storage and gpu are left out while I’m trying to get it to post at all to the bios

*ive tested this with another Psu as well and still the same problem
