PC always having issues booting, possible PSU issues?

[Varsh]

Ever since putting my PC together it was fine, but after a month of use I've always been getting the issue in the youtube video every few days. Could it be that I need a beefier PSU? I'm currently sporting a 650W EVGA G2 with an i7 4820K and dual GTX980's. I have tried several times with just a single GPU and an SSD powered for minimum required watts but I sometimes still get the same issue.

Video doesn't work, it just says a error has occured. If it's still happening with a single card then it's not likely to be the psu although you are cutting it very fine with two 980's. You would have been recommended 750-850w if you asked in here.

Even if I have the same issue with a single card? I'll try a different PSU and if that is it then I'll order a new one. I also left a link to the video.
