I was playing far cry 4 and had just installed new parts but then my pc just stopped thought it was overheated so let is stand for a moment still didn't boot note there was a weird smell but can't figure it out

If by "weird smell" you mean smoky or burnt, then something is fried. Time to visually inspect any parts for damage (motherboard, RAM, graphics card, PSU - if you have extra thermal paste around, you could even inspect the CPU).

I changed out the motherboard and cpu and still nothing so i concluded its the PSU
But didn't see anything strange about it

You may not see anything strange; the PSU is in a metal box, and that's not easy to visually inspect unless you want to tear it apart. And it could be anything from a resistor to a covered area on the PCB. The RAM may also be suspect, so I suggest borrowing a working PSU to see if that fixes the issue; if it doesn't, try each stick of RAM one at a time, in every slot (sometimes a slot dies).
