Connecting Power to My GPU

[JTHarden]

How's it goin guys! So I just got my EVGA GeForce GTX 970 today and I'm putting into my desktop as we speak and I've hit a questionable road block. So the GPU came with two 6pin adaptors but each one splits into two different adaptors that I currently only have 3 of and they are demanding 4. But I do have PCI and PCI-E adaptors with my EVGA 500 which is what i used to plug into my last graphics card and it worked perfectly. Can I just use those again? I really dont want to damage my GPU by pumping too much power into it. also in the cables the provided to be adapted in each of the 6 pin adaptors one of the pins arent filled, like its just an empty pin.

If they have the right Pins to connect to the 970 card I don`t see why not.
I presume that the connectors for the EVGA 500 used Pci-e power connectors to something like Mole x power connectors you still find on some PSU`s.

Should be ok if you have the same amount of yellow and black pairs of wires for each mole x to Pcie power block connector. Check to see what amp rating is output on the PSU you have though for the 12v power rails on the sticker on the PSU ok.

So youre saying as long as I have 2 6pin PCI connectors I would be fine without having to use the ones they provided in the box?

Well yes.
Used them myself to run 7970 Ati card with the Pci-e to molex type ends to mole x power connectors of the PSU.

And work fine.

so I am assuming you have this power supply the 500b

if so it comes with two 6+2 pin pcie cables. for these if you only need the 6 pin part just leave the +2 part hanging off to the side it is how they ae designed.

just plug those cables directly into your gpu without any adapters and you will be good to go.

on another note that power supply is just barely enough and just below nvidias recommended specs so no overclocking is recommended.

I asked around on here previously about the power supply compensation for the GPU before I bought it and I was told that it would compensate because this GPU is made to save power. My last GPU supposedly used more power than my new one

you will be fine with that power supply. I was wrong when i said just under specs. i just checked and it is in fact 500watt recomended and not the 550 i remembered.

if you are not overclocking anything you should be comfortable with that.

if you bought a msi gtx970 gaming they can take 220 watts of power. you cpu can use up to 125 watts. so that is plenty of power. It is just a risk to start overclocking.

you can see intesting that it gets close to 500 watts when overclocked

Okay gotcha! Well thanks for the help anyway! My CPU is good not great so my GPU and CPU can work just fine together with this PSU for now, when I upgrade my CPU I'll definitely have to step up my PSU game!
