  1. So I just got me new PSU and my GTX 760. I started setting everything up, and decided to test the PSU, I plug everything in and the fan spins but only for a second and then stopped. I tried everything and it sill does not work, I used my old 400w psu and everything booted.

    Could it be that my motherboard does not support the ATX 12 v2.3?
    I believe my motherboard is an ATX 12 v 1.
    Or just faulty PSU?
    I cant use my GTX 760 on my old PSU because it does not support the pciE plugs. Hopefully sombody can help me. What could be the problem?

    Have you attached your old PSU since trying the new one? This behavior can occur if you have a new build and didn't use the motherboard offsets (or left one in from an old board that doesn't match your new one and it is causing a short). Edit - Re-read the OP

    Can you boot with the new PSU without the GTX 650?

    Also your GPU should have some molex adapaters, if you old PSU does not have the PCIE plugs grab some of the molex adapters and hook it up to the 400watt to see if the machine works. If not then its likely the GPU, if so the PSU maybe bad which happens.
