So i bought a new PSU and tried setting it up but realized that the new PSU was missing the PSIE pin for my GPU, so i tried setting up the old PSU again however now my computer wont power on. I have provided pictures of what my computer looks like right now and when it was working. I tried replugging everything and taking out the gpu and trying with out it.

Calm yourself first. It is frustrating, but It can only be solved by eliminating potential problem 1 by 1.

Totally won't power on, usually caused bad connection between:
- power supply cable to motherboard
- casing power button cable to motherboard
- take out the gpu and ram first, if those above were properly attached and has nothing wrong with motherboard or cpu, it should at least start booting.

If not, then either your motherboard or your old psu has problem. You can also use your new psu.

Good luck
