I started to build my new PC this past weekend and when I tried to boot it up nothing happened.
When the psu is turned on, the case led and motherboard leds light up.
Hitting the power button give the slight sound of the psu starting up, but not even a second later it stops. The LEDs stay on but hitting power button a second time doesn’t turn on the psu at all. I have to turn off and on the psu from back to produce initial psu fan start up
PSU was tested with paperclip and it starts up perfectly fine. All cables are connected as well. 24 pin both gpu 6 and 8 pin and cpu 8 pin
