I would like to clarify, after the computer splashed the bios screen for a second and turned off, it wouldn't do it again. It's back to no display. I redid everything you suggested to try and replicate it but was unable to. So I'm not sure if that's still a psu issue or not.
well you can somewhat test the psu by unpluging it completely from the system both the 4pin and the 24pin and use a paperclip method by sticking one end of a paper clip into the green wire on the psu and the other end of the paperclip into a black wire. DO NOT put the paper clip in any other colored wire. The black wires are ground wire the green wire is the on/off switch. The psu should then turn on and the fan should spin. Basically just turn it on for a minute. If it stays on then most likely it isn't a psu issue.
