Question New MOBO, GPU, CPU, RAM, PC won’t turn on

[STRlX]

Currently working on my PC and just tried installing a new ROG STRIX B450-F, Ryzen 5 2600x, and 2x8 Vengeance LPX RAM with a new Sapphire Pulse RX580.

The PC doesn’t turn on and display, but the motherboard seems to be receiving power.

How old is that OCZ PSU?

Want to say 5-6 years, it’s been running fine so far

RESOLVED: Tried a 700W newer PCU and took apart the PC and put it back together. Everything up and running again!
