Hello,
I have recently built my first pc with an ASUS Z170-AR Motherboard

http://

and a EVGA 500B Power supply.

The MOBO has a EATX12V connector and the PSU only has a EPS12V connector. I assumed that it didn't matter (even though the square hole didn't match the "D" ones) so I have connected these two together, and, randomly, while using my computer, the power seems to flicker on and off... I think it is due to these two connections, or are these two compatible?
-Thank you
