6/8 Pin PCIe to 4 Pin PCIe adapter

[brytrickgaming]

Yes, you read the title right. A friend of mine is needing an adapter that goes from either a 6 or 8 Pin PCIe power supply connector to a 4 Pin PCIe connector. Not a 4 Pin Molex. Does anyone Know Where to get one?

There is no 4 pin PCIe power connector (AFAIK). What card is he trying to power?

It goes to his motherboard

Then it's not a PCIe connector. If it's a 4 pin, it's most likely going to be the EPS/CPU power connector. The PSU should have one, though it may be an 8 pin or 4+4 pin cable. A PCIe connector wouldn't fit. 

 

Could you post a picture (or tell me the motherboard model) and tell me the PSU he has. Unless he's missing a cable from the PSU (if it's modular) or if the PSU or motherboard isn't using the ATX connector standards, you shouldn't need any additional cables.

Okay, and the power supply he has didn't come with one. he just recently replaced the old PSU with the one he has now.

What PSU is it? And is it the connector towards the top of the motherboard, somewhere around the CPU socket? 

 

Unless there's a missing cable from a modular PSU, it will have the connector if it's the CPU power connector.

I don't know what PSU it is. Also, yes, it is the connector near the CPU socket, but I do know that it is not a modular PSU.

Any power supply made in the last ten years is going to have the 4+4 pin power plug. And it's normally hardwired with the primary 24 pin harness on almost every modular PSU I have seen. 

 

Unless you managed to find some sort of mutant chinese manufactured non standard PSU. I suppose that is possible.

Then it most certainly has the connector. It's required for the system to power on, so all PSUs will have it. 

 

As I mentioned before, the connector may be an 8 pin connector or 8 pin split into 2x 4pin connectors. If that is the case, he can just plug in 4 of the 8 pins, either side of the 8 pin will work. They're keyed in such a way that makes it impossible to plug it in wrong, so he doesn't need to worry about getting the orientation wrong. If it's not in the correct position, it will not connect. 

 

EDIT: It will likely look like this. Plug one of the 4 pin sets in. If it's not split, just plug one side in as if they were a split pair.

The only connectors he has that are free are a 6 pin a 6+2 pin and an 8 pin that does not split into a 4+4 pin, also he has the 20/24 pin connected. Its the connector next to the CPU that he needs the 4 pin for.

Got some pictures of this setup? My money is on the 8 pin being the one you're looking for; if it fits in thats the one, they're keyed differently from a PCI-E connector.

The only picture I have of the build is of the motherboard, where the 4 pin would go.

Okay, so turns out that the 8 pin did fit in the slot ( as in one side went in) but it still dis not work, (he did try the other side). So, he said he would just try and find another power supply.

It should work fine, I doubt it's on the PSU end. I have an 8 pin in a 4 pin connector on one of my systems, it works fine. Chances are if he changes PSU it still won't work as there's most likely something wrong.

Okay, thank's for the help and i will let him know.
