PCI-e Graphics Supplementary Power Connection

[jac0b84]

I recently installed a Sunbeam NUUO 550 in my rig and had some problems with the 6 pin PCI-e connector. This is a modular PSU and there is a 6pin to 6pin connection that I hooked up to my 6800 gt. That end of the card began to overheat and my graphics intensive applications would not run very well. I immediately unplugged the 6pin connector figuring I overlooked an incorrect compatibility between the power coming out of the PSU on that 6pin. I know that a simple solution to this would be two molex connectors and an adapter, but i had two questions before i created more clutter in my wiring. Also my rig is working seemingly fine without this extra power connection to my GPU.

Is the 6pin connector necessary when I have a 24pin PSU to MOBO connection?

Is anyone familiar with the 6pin connection coming out of this specific PSU?

Thanks guys,

If you card needs the extra voltage it should be fed the extra voltage. I have an X800XL and it has no power connector its powered by the pci-e slot. I guess as long as your card is running fine without it than dont worry about it.
