Hello all.
I need your help.

I just powered ON my build for the first time and:

- MB ASUS VI GENE, lights up;
- GPU, CPU and chassis coolers spins;
- Monitor displays the following message - "Please power down and connect the PCIe power cables for this graphic card".


1. Connectors on ASUS GTX770 GPU side are:


- one 8 pin "slot" ----> (6+2) cable IS connected;
- one 6 pin "slot" ----> Not connected.

2 I have Enermax Revolution 87+ 750w
Cables available:


What cable do I use 6 pin power conector?
Thanks!

Yes 6 pin. I was just editing the typo .
The question remains.
Thanks!

You should find that only one cable fits - the 6-pin part of the one in the middle is my guess.

From the PCIe 6+2 cable connect the 6 pin (leave the 2 pin not connected).

I'm sorry, but this isn't specific enough for me :/  I have my PC working fine, but the cables look untidy, because I've used a 6+2 pin to 8 pin adapter (incuded with GPU) and have another 6+2 pin plugged in (w/o the 2 pin) in the 6 pin slot. I'm using the Asus GTX 770, with a Corsair RM750. PCIe cables supplied are the same as above (obviously look different) - but which cables do I plug in where? There are two lights on the PCB (currently both green). Thanks

6+2 pin and 8 pin are basically the same thing - the 6+2 pin just has the 2 pins separated so that they can plug in to 6 pin power ports, whereas a pure 8 pin cable cannot be put in a 6 pin port.
Just put the 6+2pin cable in the 8 pin port and a 6 pin cable/6pin part of a 6+2 pin cable in the 6 pin port.

I've tried, but I can't even use the two in unison because the 2-pin has a plastic overhang (not defective) on the side facing the 6-pin :@ It's really annoying, WTF did they do that?!

Post a picture of the cable where you think this problem is, I'm unable to visualize it.
If you're talking about a slider-type arrangement, then that is to lock the two parts together such that they act as a 8-pin. You will probably find a similar arrangement on your 24 pin motherboard connector; that is also many times a 20+4 pin.
Also, you'll find a similar arrangement on your 8-pin CPU connector. That is, however, not a sliding but a snap-in arrangement. That can be converted to 4+4pin for CPU's needing only a 4-pin power connector.

Ok thanks, it turned out the overhang WAS meant to slide over the 6-pin plug (but it was tricky). My PC looks much tidier now, thanks :)
