CPU Power connector confusion

Box Canyon
 Share

Building my first new system in about 10 years. I was a bit confused by the CPU power connector situation, and want to know if I am doing this right

My motherboard is an ASRock 470 SLI.

It has two CPU power connectors.  One is referred to as V1, 8 pin, the other is V2, 4 pin. 

My PSU connector (EVGA) has two 4 pin connectors. Both are now plugged into the 8 pin socket.  One has all beveled pins, the other has two square pins. Pin with two square pins is on the right, pin with all bevels is on the left.

The clips are latched properly on the correct side.

 

So, to clarify, I could use the ONE 4 pin connector with the square pins on EITHER the 4 pin socket, or the right side of the eight pin socket, OR both connectors the way I have them. Correct?

 

What threw me is that all four pins of the leftmost connector are BEVELED, but the socket has all SQUARE receptacles.  I assume this is all correct, and no smoke will escape when I power this up.

both in the 8pin, that's enough. You can leave the 4pin socket empty
