So I had my i5 6400 non k oc'd to 4.8 Ghz at what I thought was 1.35 volts (was actually pushing nearly 1.5, didn't use voltage ID tool) on a hyper evo and so it halfway booted into the bios a few weeks ago and just died. So I RMA'd the mono and the cpu, and I was wondering if there's any chance that my PSU IS AT fault. I know it's probably my ridiculous on air overclock, but I was just wondering if there's any chance the cpu power cable pushed too much wattage into my mobo and killed it. Any answers are appreciated.
PC was stable at these oc'd settings for over a month by the way.

Using a volt meter, there are 2/4 negative and 2/4 +12V leads, with no other voltages detected. The measurements fall within +/- 5%.

Yes, it's likely that the VRM on the motherboard failed.

It's feasible, though the most likely cause was the VRM on the motherboard failing. Can you check if the CPU power cable is intact and functioning properly?

Yes, employ a volt meter; there are 2/4 negative and 2/4 +12V leads, with no other voltages present. The measurements fall within ±5%.
