Mid Build, Stuck!

[KingKj52]

Using an MSI Z87 MPower Max AC motherboard, and an EVGA Supernova Nex750B1 Power Supply. The CPU power cable (Which I assume I need for the 4790k) comes with a 4+4 Mulex: The problem is one of the 4's is correct (patterned square/dome tips) but the other 4 is all dome-topped, which doesn't match up with the motherboard. There is a second CPU power cable I was going to use as well, and it is the same way. Do I plug the all dome-top tips into the varied ports? Note that the 4+4s are going into 8 slots. This is my first build with modern hardware (last built before DDR3 was a thing lol) and I'm on skype with my friend and he is confused as well.

My friend's attempt at explaining it:

"his problem is (we're in Skype talking about it) that the "cpu connector" has the wrong type of attach. https://drive.google.com/file/d/0BxmbTklAkJ55T3h4MEdKbjJNbFE/view[1][1]as you can see, they are all the dome ones, they don't have the square corners and domed mid on top. edit: the question is what to do, and what that connector is for"

about it but little help was provided, other than help that wouldn't? work.

Looking for help here.

It will work fine. I actually have a spare EPS cable sitting next to me and it's the exact same and works fine.

Are you sure you are using the right connector? You might be using a PCI-E connector for your 8pin CPU.

So I plug the 4 domes into the normal slot and it works fine, right? Just wanna' make sure before I run a test and power this bad boy up.

Yeah, the cables are labled as CPU1 and CPU2.

Yep. 

 

EDIT: Here, a picture of the cable. I have the exact same for my 8pin CPU.

So I've hit two alternative problems I was wondering you could help me with.

1) On the VGA 6+2 connectors (to hit the 8 slot of my 970) one of the connectors is supposed to be a square and its dome shaped. It still snaps in fine. Will that be ok? The original 6 work fine, the odd one is on the 2.

2) My PSU only has 3 VGA slots (a hardwired one and two modular ones), but I need 4 (I have two 970s ready to run in SLI). Is there some adapter I can buy to give myself an extra slot (I'd also need an extra cable I assume, as the PSU only came with 3).

First one is fine. 

 

You can get molex to PCIe adapters. Search on somewhere like Newegg or Scan to find one.
