Question PSU change leads to no signal

[retardQwob]

Hello,

I’ve recently upgraded my PSU as the old one was acting up. I installed the PSU and tried to ensure that I replugged all the required ports, the PC now turns on but never connects to the display. I tried using the old PSU again with no luck. Does anyone possibly know why this could be happening?

Thanks in advance

Brand and model of both PSUs?

Reset motherboard BIOS.

Wait a minute.....

You used your old cables?

What was the old PSU and what's the new PSU?
