T5600 1300W psu, won't power on
I got a T5600 and needed to upgrade from the 635W psu to accommodate a beefier GPU. I was under the impression that the PSU's were the same as the T7600 and ordered a h1300EF-02 but now that it's here it won't power on when it's installed. The PSU's self-test works, but only when it's removed from the computer. I've tried everything up to completely removing the PDB and even with no cables installed and removed from the case and it acts the same.
The 635W still works and runs so the board and PC is fine.
I can't find any information on this issue, or really for the differences between these PSU's.
