PCI-E Cables?

[Booker, Catch!]

Bear with me I know very little about Pc building. So I have a GTX 1070 and it has two slots with 8 holes in each. It came with two bags, in which each has a corresponding 8 hole plug, that goes out to two 6 hole plugs. My power supply unit has a plug named PCI-E that connects to this, but only one. That means that the other two 6 holed plugs do not have a way to connect to my power supply.. I am positive I did not lose any pieces from it. Is there a way I can buy another cable, or can I make use of all of these cables that aren't being used to somehow connect my power supply to the other plug my GPU needs?

Depending on what brand your PSU is, it could simply be too weak to power a 1070 which is why it only has 1 PCI-E Power plug.

If youre upgrading a prebuilt PC that could very well be the case and you will need to replace the PSU as well.

You're misunderstanding how the plugs work/connect.

Alright. A PCI cable has two ends, and they're not interchangable. One end has to go into the PSU, the other end has to go into the GPU.

The PSU end has a single 7-pin connector. It has 8 holes, one of them is empty. Mine has 760/860 ONLY written on that end, yours may differ.

The Graphics Card end has two plugs and they both have PCI-E written on them. Plug these into the GPU - both of them. You must USE A SINGLE PCIE CABLE and both of it's plugs, not two cables. I don't know what would happen if you used to, but it's best not to find out with a card that expensive as the guinea pig.

If your PSU has only one PCI-E cable then it's most likley too weak for your GTX 1070.
You need 500W or better PSU with two 6+2 pin PCI-E cables, 6 and 2 pin part clip together and go into 8 pin socket.
Those cables that come with your card are adapter cables and it's not really recommended to use those with some weak PSU that doesnt have enough watts and amps to run GTX 1070.

This is decent enough PSU for GTX 1070 if you dont plan to use two GTX 1070:

I'm fairly confident that my power supply is enough to support it. It's a gold standard 550 watt xtr. I've asked around the internet and people said it would be plenty to support my GPU for the time being, which is why I'm confused as to why I'm having to buy additional parts for it.

Booker, how many PCI cables are you trying to use for that one card? You should only need one PCI cable port on your PSU for each card you add.

The cable that says PCI is split up into two pieces, each piece is 6 holes. My GPU has two sets of two 6 holed pieces. The PCI cable I have now is half of what I need. I don't know if it's important but it has 2 stray pieces with just two holes attached to it.

That's really unusual, I've never seen that before. What make and model of 1070 is this, if you don't mind me asking?

All of the GTX1070 models I've ever seen have 1X 8-Pin and 1X 6 Pin, or just a single 6 or 8 Pin. Not even my overclocked GTX1080 needs 12-pins.

If you have 550W XFX XTR then you will be fine. It has two 6+2 pin PCI-E cables, find them and plug both 6+2 pins into both 8 pin sockets. Like I said 6+2 pin clip together to form 8-pin plug.

Here is the picture of the cables you need:

Those can be used as needed to any configuration of sockets in your graphics card, if there is 6-pin socket just use 6-pin part and if there is 8-pin socket clip 6+2 together and use that.
Just make sure that all the power sockets on the card are filled.
Ignore the adapter cables that were supplied with the card since you dont need them if you have two 6+2 pin cables on PSU.

It's an EVGA FTW, I'll try to do what Rumpel suggested, but I'm not sure if my PCI-E cables even have 12 holes themselves.

[Cathulhu]

EVGA? You mean those that literally burst into flames?

[Arya]

Yeah... you might want to refund that card ASAP. EVGA FTW have a massive design flaw that's been causing them to spark/catch fire.

Okay so if I add the 2 hole plugs they are enough, but the 2 hole plugs don't seem to fit like the 6 hole ones do. Are they supposed to stick out a little bit, or do I have to apply some force?

[Revelene]

6+2 pin should plug in the same as an 8 pin. Put them side to side, you'll see how they fit together and it should plug in all the way, evenly. If it sticks out, then you don't have it clipped correctly.

Not a design flaw, but rather a bunch of bad capacitors. Not all of them are going to explode, but I'm sure there are quite a few of them, especially if it was an entire batch that was bad.

Not just capacitors, friend - they forgot to install Thermal Pads in a bunch of FTW and SC cards.
