Plugging 7950 into PSU

Hi everyone,

Apologies in advance for such a basic question. I'm putting together my first build and am having a bit of trouble figuring out how to hook my graphics card (Gigabyte HD 7950 http://www.overclockers.co.uk/showproduct.php?prodid=GX-098-GI) into my PSU (Seasonic G-Series 550w http://www.overclockers.co.uk/showproduct.php?prodid=CA-018-SS). One of the PCI-E cables plugs in to a 6 pin socket on the graphics card and an 8 pin socket on the PSU labelled PCI-E (so good so far). However, there is also an 8 pin socket on the graphics card which can only be connected to the molex adapter provided with the card (the other PCI-E cable (6+2 pins) does not fit). This plugs in to the power supply via a 6 pin connector labelled Peripheral - IDE/SATA on the PSU, is this correct? Terrified of hooking it up wrong and blowing any components. Hopefully I've explained this clearly. Any input would be hugely appreciated!

Cheers
 
That PSU comes with 2 x 6+2 PCI-E connectors, so should plug in with no problems. The extra 2 pin should just be moved out of the way.
 
Thanks for taking the time to reply guys. With the graphics card hooked up to the PSU via the two PCI-E cables provided it wouldn't power on. The card has two power inputs; an 8 pin and a 6 pin. Although the PCI-E cables provided with the PSU both have 6+2 pin connectors they wont fit into the 8 pin output, should the graphics card power on with only 12 pins plugged in rather than 14? Thanks again for the help, it is greatly appreciated.
 
Are you perhaps using the CPU power cable? It will be labeled "12V" or "CPU" perhaps.

PCI-E (graphics) cables are usually labelled PCI-E, PCI-E 12V etc

That PSU is semi modular, so no way to get mixed up.
It comes with two 6+2 pcie cables, i'm not sure why they're not fitting...have you tried both?
 
Well I'm feeling a bit embarrassed now :o, managed to get the 6+2 PCI-E into the 8 pin socket on the graphics card. Thanks everyone for taking the time to help me out and apologies for wasting your time with my idiocy!
