NEED URGENT REPLY! PSU didn't come with correct pins for my GPU??

[Snazzymacguy]

Hello all, let me get straight to the point.

My PSU is an EVGA Supernova 750w G2 80 Plus Gold.
My GPU is an MSI R9 390.

I installed my GPU looked for the correct VGA cables in the PSU box. The GPU takes an 8 pin followed by a 6 pin, and obviously another 8 pin is needed for the connection to the PSU. However, all that was in my PSU box was an 8 pin connector with a 6+2, another 8 pin connector with a 6+2 and yes... another 8 pin connector with a 6+2. In total it came with 4 of these.. I need a cable with one 8 pin and 6 pin for the GPU and an 8 pin long enough to reach my PSU from the GPU. I have no idea what to do now and I don't know where to get an adapter! I searched online but I can't find any. All help is appreciated!
Also, my GPU came with a short cable that has 8 pins on one end, which are smaller than the 6 pins on the other end. Is there any way I can make these work?? I'm clueless.
Thanks!

You can use a 8pin with a 6pin from the 6+2 just leave the +2 hanging if you know what i mean.

Yeah I get it but there isn't any 8 pin to route back to the PSU.

maybe post a picture of what cables you have spare? because i am not sure anymore.

but cant you use 1 6+2 for the 8 and 1 6+2 for the 6?

If I connect a 6+2 to the 8 and connect that one to one of the VGA sockets in the PSU, and then use another one of the cables 6 for the other GPU slot (with the 2 hanging) and the other 8 back into the second VGA slot on the PSU, is that meant to work? Because I tried that.
Pictures incoming btw!!

First one is of cable that came with GPU.
The rest are all the cables that came with the PSU, all being 8 and 6+2.

Yeah it's an 8 and 6+2, I can. But there is no other cable to route back to the PSU that is an 8 pin.
Basically the cable isn't a 3 way it's a 2 way 🙁

Oh wait, so you can use two of the VGA slots on the PSU for one GPU? I did that and booted the PC, everything was working but no picture on the monitor??
I'm just confused now please explain it lol I'd appreciate it lots!

 

[janbas]

did you put the cable on the videocard or on the motherboard slot? it should work like that (if you put the cable on the videocard)

I done the exact configuration you showed on the diagram. Just GPU and then to PSU.


Basically, is it okay to use 2 VGA ports on the PSU for one GPU? Will it still work??

 

[janbas]

yes basicly its okey ^^ but are you connecting your monitor cable to the videocard not the computers motherboard?

Yes to the video card

 

[Snazzymacguy]

Omg I'm an idiot... Connecting to the mobo instead of video card fixed it lool...
Thanks so much janbas!!!

 

[janbas]

haha you are welcome!
