Hi,
I have a cooler master 650w PSU with 49 amps on the 12 volt rails. My video card requires two seperate molex connectors. Should I connect one rail or connect two seperate rails to the video card? thanks, Grady

Are you running two video cards?

if you only run one, your PSU should have two PCI-E connectors.

if you run two video cards and require more then two PCI-E connecters, you can connect the molex to any of the molex connectors coming from the PSU since your PSU only has one Rail

1 video card! 2 molex connections on the card (AGP) Should I connect 1 rail, or two
rails. I have two 12V rails available on my PSU and I connect my HDD and optical drives with SATA.
