Hi, I've got a G5 quad with the pci-e slots. I've got an Nvidia GeForce 7800GT already in the machine, and just picked up an ATI Radeon x1900 Mac edition to run a couple more monitors. The problem I'm running into is how do I supply power to the second card since the only 6 pin pcie connector I can find on the mainboard is going to the 1st video card? Does a splitter exist, or if I spliced two cables together would enough amperage be supplied? Both cards run off of a mini 6 pin pcie to standard 6 pin pcie cable. Any help would be much appreciated. Thanks!

P.S. This may be a crazy alternative, but I've got a pc I always run right alongside the mac that has a couple extra pcie power connections available. Could I run a power cable out of the pc and connect it to the Radeon card in the G5?
I saw an older thread where about midway down someone mentions successfully adding a radeon 1900 as a second card in the G5, but it never mentions the power connections. https://forums.macrumors.com/threads/436693/
