Can I run a single Gigabyte WF3 7950 on a single 12v rail? - Page 2

post #11 of 25
Rails don't matter much with power supplies. What matters is 4 things:

Build Quality (which means better ripple suppression and voltage regulation)
Wattage
Amperage

You can power 2 7950s off that PSU with an i7 3930k at 5GHz, 6 hard drives, 12 fans, and a leaf blower with that thing.

Lol I'm no psu expert either but I think I'm just not being clear. Can I split the one 6+2 part of the one 6+2 / 8 pin cable into 2x 6 pins and run the 7950 off of that one cable?

No.  You'll need to use those Molex to PCI-E adapters.  They're ugly, but they work.

Mind if I ask why it will not work? I have the adapter to split it to 2 6 pins.

That's a good question, but why not use the Molex to PCI-E adapters in order to convert two molex cables into one 6-pin PCI-E cable?

Well I have my only 2 molex cables in use is all. One is being used to power my Corsair H80 and the other is being used to power all my fans rather than the mobo because well ... I have alot of fans haha.

Wow, this PSU sure is lacking in connectors for an 850W power supply.

 

At this point, all I can say is, again, report your original post in order to request that your thread be moved to the Power Supplies forum.  This will definitely increase your chances of having someone reply who knows for sure.

Did you lose the cables for this psu, or not enough ports? From its specifications it has 6 pci-e cables with a 6+2 connector each, and two molex cables with 3 connectors each.
