Restarts during startup

[tyrantwing]

Hi everyone, I'm having trouble with my pc now. I just bought a new graphics card, case, and psu.

 

I finished putting it all together and it posted, got to the desktop and the it restarted shortly after. 3rd time it stayed on for about 5 minutes then just started going on and off.

 

The psu is a Corsair CX7500m, referb.

Any thoughts would be great at how to solve this. Thank you.

What case? Corsair C70?

It's the PSU. Snazzy Labs had the same problem when he build his new PC. The Corsair AX power supply he bought was a referb and had the same problem you are now. Here's the video if you wanna watch it.

Corsair 380t is the case.

I did buy a replacement plan for the psu, I can take it back. Any chance the card could be doing it, or that I didn't connect the power right?

Does the gpu need 2 separate power cables or can one be enough?
