Quick help on GPU?

RageSaul · May 4, 2013

Hi, I am in the process of doing an external build, I got everything hooked up, and I am just connecting my PSU to my GPU.

There are 2 ports on it for power cables.
1 6 Pin that i already plugged in.
1 8 Pin that is a problem, my PSU has 8 pin cable, but it is split into two. Is is necessary to plug the 8 pin in? New eggs video shows him only plugging in 1 power cable...

Thanks

is the 8 Pin split into a 6+2 or a 4+4 config? If its 4+4 don't put it in, its intended for CPU's.

You HAVE to plug in the 8 pin otherwise you won't be able to game at all really. Mind telling us what your GPU is?

I have a radeon 7970. The 8 pin is split into 2x2 things. It is split half, so 4 and 4. Thanks

That's a CPU connector then - should be plugged in at the top of your mobo (unless a PSU with two EPS12V cables). You want an 8-pin one that splits into a 6-pin and a 2-pin, or just a whole 8pin that cannot split. Should have PCI or PCIe written on it.

You might be able to use one of these if you have a good enough power supply:

Ok, so.

There are 2 8 PIN cables, the one that doesn't split is the supplemental CPU power lead and the other one that is split I don't know what to do with.

The main mobo power is connected and a 6 pin is in the GPU

This is an external build btw.

Look up your power supply specifications. The split 8 pin is usually for the motherboard so it will work in older boards that need only 4 pins. The solid 8 pin is probably for pcie graphics cards. But don't take my word for it, please check your power supplie's manual or on-line specs.

Alright, so I got a 4+2 pin connector and a 4 pin in the GPU, so that's sorted. Now in the manual it says there are 2 CPU cables, 8/4 (2x4 pins) and just a whole 8. Right now there is a 8 pin in it for the CPU, is that right? Or should I use 8/4 Pin one?

Thanks

You really have me confused now.

I'll give you a picture, 1 second.

BUMP doesn't seem to be working, basically I got a full 8 pin cable and one 8 pin cable divided in half so 4 pin and 4 pin, which one do I use for my CPU power?

zdbc13 · May 4, 2013

Usually the solid 8 pin will be for pcie graphics cards and the split 4+4 will be for the motherboard. But as I said, you should make sure with the power supply's manual or on-line support. Good luck.

I have plugged everything in, I have 2 available cables for the CPU, 8 pin or a 2 - 4 pin cable. GPU is hooked up already, so I still have 2 cables and I can use 1 for the CPU, I'm asking which one...?

Thanks though

Doesn't matter now

IT WORKS!

Now to put in the case. I'm so happy xD Nothing beats the feeling off successfully putting parts together. Thanks all
