I pulled my old 850 EVGA power supply and put it into my new computer that I built. To make my old computer more sellable to maybe someone who just needs a desktop for light use, I bought an inexpensive 600 watt EVGA power supply. The old computer doesn't even have a videocard in it anymore but it does have on board graphics via the CPU. Hardware-wise nothing has changed in the computer. When I press the power button, the computer lights up for a second and then turns off. I made sure to use all of the cables that came with the new PSU. Thinking it was a bad PSU I exchanged it for a replacement of the same brand and model. Same issue.
If I had a theory I noticed that the CPU connection might be the issue. You know how the plug has a bunch of squares and rounded squares in a grid shape? The CPU ports appear to be different than the ones that are provided with the PSU. See the two links below:
