Need help with troubleshooting failed to boot issue

[tle]

I posted a video outlining the issue I have with my blackbird at https://youtu.be/8r1HVoI3_8g?si=NhNTnHAdR-HJLJit

TL;DR; 2 days ago my old PSU died. So I replaced it with a new PSU
and now my motherboard refuse to power up.

Any help is greatly appreciated

Have you tried another PSU?

Great thanks. It turns out the new PSU is faulty. I have tried other PSU and they work perfectly.
