Need a pair of these 8 pin pci-e to dual 4 pin molex power cables to power a pair of 3870x2's.

Is your PSU really going to be enough?!! I should have the adapters, I'll have to do some digging into the pile.;)

what brand model exactly is your PSU ? I've run 2 x 3870 x2 on 650w antec trio power no problem with the adapters.

The molex power isn't meant for using powering PCI-E at all (75w power draw).

box says 750w for 2x 3870x2 but i ran fine on my 650w antec with Q6600 at 3.8 and oc 3870x2. the 6 pin PCI-E to 2 x 6+2 pin PCI-E will provide better power delivery than the molex adapters if you decide not to upgrade the PSU to like an 850w or so.
