Only 2 6 pin connectors on PSU

[Imjustbrian]

So have done a bunch of research, going with a R9 390X gpu. I have a 650w PSU, but it seems to only have 6 pin connectors, I do have a "dual molex" cable (think that's what it's called based on another thread) that goes from six pin to two four pin cables. Would that work? I honestly don't want to change the PSU out, more because it looks like a pain to disconnect/reconnect every thing then price wise, but if I had to I would.

What model PSU do you have? A 650W psu should generally come with a 6+2 connector

I have 650w ATX 2.0 PSU w/active PFC. That's the description given on the paperwork (I didn't build the system myself)

Thing is when I looked at the PSU and cables I had several six pin cables (two cards installed with six pin and another six pin cable free) I noticed at least one tiny two pin cable and didn't know what it was for, seems that adds to the six pin to make it an eight pin based on the video I watched to install the card?

If your PSU only has 1 12V rail. You should be able to get away with getting 6 pin PEG to 6+2pin PEG adapters. Other wise you might want to get a molex to 6+2 pin PEG and one of the adapters I mentioned before. This will help with load balancing. I'm sure you can find cheaper examples then the ones I provided, but I'll link them as reference.

Look @ this image: http://www.mechbgon.com/build/8-pin_pcie.jpg

That's a 6+2 connector. Basically, an 8 pin connector. If your power supply has that, you'll be fine. Just make sure you get a 390X with an 8 and 6 pin requirement and not an 8 and 8 pin requirement.

I have three of the 6+2 connectors (two currently used, one not used as I only have two cards installed) so it seems I'll be good. As always, you guys rock with the information and the speed of it. Thank you very much!
