I plannned on ordering another 5850 to Crossfire, but I'm curious...since I only have 2 PCIe 6 pin connectors on my psu (700 watt), will it create an issue if I try to power a card with 2 4 pin molex to 6 pin pcie cables or even use 2 6 pin pcie splitters? Either way....I need a total of 4 6 pin pcie's for this to work and I only have 2.
