XFX pro 850W 80+ bronze
box says 2x 6/8 pin, 2x 6-pin, 24-pin mobo, 8-pin cpu along with abunch of molex and SATA connectors.
You can try to plug one 6-pin and one 8-pin plug to your card.
Or you can look for PCI-E 6 to 8 pin adapter, like this one
Thx for your help, gonna order a couple of those right now.
@bardacuda good luck mate, tell us how it went
Thanks, I'm gonna need it!
EDIT: Check your 6-pin connectors and make sure they have all 6 pins. Most of them do but one of the 3 +12V pins is not actually required by PCI-E standard. If it only has 2 +12V pins I wouldn't try to adapt it into an 8 pin.
