how to connect 8-pin power supply to a 6-pin graphic card

Hi experts,

I have a question on how to connect the psu power connector to a graphic card power connector.

The graphic card is xfx R7 260X. It has a 6-pin PCI-E power connector.

My psu is Seasonic 620GM. I used up other power supply and only has a 8-pin power connector left.

I first thought I may just need an adaptor from 6-pin to 8-pin, then it should work. Then I read some articles on the web and seem that there are more than that.

http://www.overclock.net/a/gpu-and-cpu-power-connections

And I see specifically in the warning that come with the graphic card that "The 8-pin PCI-E power connector is not the same as the 8-pin CPU power connector. Please ensure you connect the correct one."

So, now I have a second though and double that if the 6-pin to 8-pin adaptor can solve the problem.

Please help.

As I can see on seasonic site:
http://www.seasonicusa.com/M12II-Bronze.htm
this PSU has 6-pin connector, so you should only find proper connector (PCI-E 6P, should be in a standard PSU set) and connect it

@als315: Thanks, after the previous post, I took down the psu from the case and do see the 6-pin connector. I will look for a cable connect directly from psu to the graphic card.

Next thing I notice is that both the psu and gpu have 6-pin male connector build in. So, we will need a female to female 6-pin cable to connect them. It seems that all the extension cable has one end as male, the other end as female.

Am I on the right track?

I do not see anything that has female at both ends.

Thanks,
RDB

Special cable PSU-GPU was included into the PSU set of cables. Try to find it. Did you install PSU yourself?

@als315, yes, I installed psu long time ago. Cannot remember if there was other cable I did not use and could not find anything in my tool box where I usually keep my extra accessories.

I looked at my psu again. Referring to the seasonic picture in your previous link, only two output slots from the psu was used. They are both at the right side of the picture. So, both PCIE 6P slots are available.

Yes, I need to find those special cable. If not, where do we buy them?

Thanks,
RDB

Be extra careful when you purchase/buy those cables since there's no standardization for plug entering PSU (as much as I know).
You can kill your graphic card if you get wrong cable. So far I know for two cases of wrong cables and dead equipment.

I think it is much safer to go for 5.25" Molex to PCI Express Graphics Card 6pin Power Cable Plug, in case that you have two free molex plugs. But, try to find your original cables if you can, PSU rails will have less load, and that will prolong PSU lifetime.
