[SOLVED] Must Unplug PSU cable to boot. Can anyone fix this problem?

[AidanChiu]

I built a PC recently and have been using it a lot. When I turn on my PC, everything turns on (lights, fans, trouble shoot LEDs are good, motherboard power LED), however there is no monitor output. I must unplug PSU, hold power button, then replug and turn on, then the monitor will recieve signal. Can anyone help me ?

Welcome to the forums

What are your system specs?
if you are manually needing to power cycle the PSU I would start there. do you have another you could swap out for testing?

i don’t have another psu i could swap with, due to corona situation where i live.

I can ask my brother to lend me his PSU to test this, i will test it later and report back!

you will need the motherboard and the GPU powered if you want to boot the system.
