[Solved] Want to crossfire ATI 5870's, but don't understand PSU connections

I want to add a second ATI 5870 to an existing system. The power supply is 750 Watts and is modular. However, the 5870 requires two 6 pin PSU connectors and the PSU only has two of these. How do I provision the second set of two six pin connectors? I have at least three new modular power supplies and none of them has more than 2 connectors for the graphics cards even though they are all SLI/Crossfire certified.

Thanks!

What power supply is it my friend ?
I don't know your level of understanding but are you by any chance ignoring the 6+2 8 pin connectors ?
PCIE connectors is what they will be labelled anything that says PCIE on it is for the graphics cards.
You can use the 6 pin part of a 6+2 connector just fine.

Thanks, when he gets his lazy whatever out of bed, I'll go check the connectors more carefully. As to type of PSU, I'll have to have a look at it to see. I did just replace my other son's PSU with an OCZ ModXStream 700W pro. It has 2 PCI-E (6 pin and 6+2 pin). Sounds like that one would need a molex to 6 pin. The 5870 takes 2 six pin connectors. If need be, I can swap those two PSU's.

+1 Good point.

Not a problem glad you are sorted.
