Powering msi 1070 gaming x

[1Kody1]

I have a corsair cs750m 80plus gold fully modular power supply. Now, my question is with the 1070 it says 6 pin and 8 pin.
My psu looks like this: http://imgur.com/a/GMc1A
I only have the 6+2 pcie spot & 4+4 cpu spot open.
I bought this from CyberPower and they said they don't "officially" support third party stuff for liability reasons. They said that if I use the 6+2 as an 8 pin into the gpu it should work. I just want to make sure that using the 8 pin alone can power the 1070.
If not, is there any better way to do this? Like can I use the 4+4 cpu somehow?

You should use all your power connection ports on your GPU (On any computer component for that matter). Less chance of it overheating or blowing PCB trace (if a component will draw 100 amps, its better to have 2 cables sending 50 amps each versus 1 handling the full load of 100 amps). If a connector will fit into your socket on your GPU it *should* power it appropriately. They are all "keyed" so you don't put them in wrong.

I see what you're saying, it's better two at 50% than one at 100%. Could anyone shed some light on how I could go about doing this? I need a 6 & 8 pin, only have the 6+2 and 4+4 cpu spots on my psu.

The GTX 1070 would require you to plug an 8-pin and a 6-pin PCIE power cable from your Corsair CS750M PSU.

Your PSU is a semi-modular unit, wherein, the 24-pin ATX and the 4+4pin ATX12V/EPS cables are attached to the PSU itself. The rest of the cables are detached. You should have, in those detached cables, two PCIE cables with two 6+2pin connectors each (total of four PCIE 6+2pin connectors all in all). It looks like this:

You cannot use the 4+4pin CPU (ATX12V/EPS) cable in the 8-pin socket of your GPU as 1) they won't fit, and 2) they are wired differently:

Add to the fact that the CS750M only comes with one 4+4pin CPU cable that is attached to the PSU frame, so, since you'll be plugging that into your motherboard, there's no other 4+4pin cable left.

So, for your GPU power, you will only use one PCIE cable which already have two 6+2pin connectors as mentioned/shown above.

At the GPU-side, you plug the first 6+2pin into the GPU's 8-pin socket, then, you plug the second 6-pin (excluding the 2pin) into the GPU's 6-pin socket (leaving the 2-pin unattached). Like this:

At the PSU-side, you can plug this PCIE cable in either of the two 8-pin socket you shown in your photo link. Both sockets are interchangeable (can be used for PCIE or CPU cable) as far as this PSU is concerned.

Alright, I"ll look for those 6+2s you are talking about. So just for clarification, it's going to be something like this?

And I"ll plug it into

Also, is the PSU really only a semi-modular? On the invoice it said fully.

Ah, I see your pictures now. For some reason they weren't there.

Yup, glad you were able to see the photos I posted now. For the second photo you linked (the red encircled socket), yes *or* the one below it (either-or, depends on which socket you like).

The CS750M is not fully modular. Official webpage of Corsair showing the said PSU only terms it as "CS Series(TM) Modular CS750M - 750 Watt 80 PLUS(R) Gold Certified PSU" (http://www.corsair.com/en-us/cs-series-modular-cs750m-750-watt-80-plus-gold-certified-psu). The "Modular" must be the reason why the seller assumed it to be "fully-modular", when in fact, "Modular" can mean "fully" or "semi". The CS750M is semi-modular (due to the attached ATX and ATX12V/EPS cables).

Ah, I see. I bought it from CyberPower, surprised they had it listed as fully modular. Thanks so much for your help, I can't wait to get it setup when it comes in tomorrow. This 750ti is killing me, I have way too many games that are barely playable.

Well, it's working. It was a complete mess. Firstly, the GPU was so big that liquid cooling tubes were in the way. Then we had to tear apart the whole case, take apart some case fans, take off the fans for the liquid cooler. Move the liquid cooling around so the tubes would come the other way, put back on the fans.

My only saving grace was that my step-father was able to come over to assist me, thanks to him I still have a computer.
