[PROBLEM]
When the 8 pin PSU connector is connected the fans spin for half a second then the computer turns off. CPU check light of the motherboard blinks red once. Help would be much appreciated.

[TRIED]
I have tried the CPU on a different computer and it works just fine.

The PSU(new) seems to work just fine as well.
