Go to solution Solved by KenjiUmino,

when the CPU power cable was touching the heatsink you got 12V shorted to ground, triggering the PSUs safeguards (hopefully) so it shut itself down immediately. 

 

totally seen this happen myself on my old core 2 duo system when a molex connector hit the copper fins of the cooler - there was a spark and the system shut down but after tucking the cable away and pressing the power button again the system bootet right up and worked fine like nothing happened.

probably? inspect the cables - do you SEE any actual damage?

So I was Playing my Games, then My computer Randomly Shut down, & then Again after I went back to check something, & then again When I was about to open a browser for help. I opened my Computer Because I was sure it was a hardware Problem, & it was. I saw somemarks On my Heatsink because the CPU power Cable was Sticking to it. I moved the Cable Away & it was now fine. My question is, Do I have to get my PSU Checked? Because the Wires Are Probably Melted or something & will Probably Kill my Computer sooner or later

Zip-tie it down, and boot it up. If it doesn't turn on, your cable might be fried.

This. Cables are coated in rubber. If the cable is the issue, it should have scorch or 'grill' marks from the heatsink, and misshapen rubber.

Yeah I tucked it by the Side with some Zip Ties & I inspected the Wire a bit & I don’t seem to find anything bad & yes it does Work like nothing happened. Thx :)
