    I have a OCZ 500W power supply, but it doesn't have the 6-pin connector my ATI 5750 needs. Alright, so I have the splitter included with my card that splits the 6-pin into 2 Molex plugs. I'm pretty sure I need both of those plugged in, but I'm unsure of the orientation of the wires. I took a picture of how I *think* it should be set up:

    So you can see the longer end will connect to my PSU with the 6-pin, and the shorter end, also with the 6-pin, will connect to my GPU. My question is if the end coming from the PSU is right. The cable coming from the PSU end doesn't actually "split" into 2 Molex plugs. It goes to one Molex, then continues to another Molex, and then continues to a plug, that I can't identify.

    I'm assuming this is right because my PSU is "SLI Ready", and it has two of the cables you see in the picture (the longer one), meaning one for each card. Sorry if this is confusing, but I really don't want to damage anything :confused:

    I can answer the plug you don't recognize part for you. It is a Floppy drive Power Plug. Did your PSU come with a manual?

    The connectoin to the PSU shown in the picture isn't what the manufacturer had in mind. Because you are connecting the Y-adapter to two 4-pin connectors that are chained together, you are pulling double the power through the PSU wires than what was intended (though it may work).

    A better solution would be to use two 4-wire connectors from the PSU that are not chained together like in your picture. Note that you could use two cables like the one in your picture and use the 4-pin connector closest to the PSU on each, and leave the others disconnected.

    It did, but it's horrifically vague. Thanks for answering the unknown plug, though :D

    Hm, I'm nervous to try either of these options, although I think your second suggestion is quite safe. I'm going to go look around through some stuff and see if I can scrounge up a 6-pin cable somewhere first, before I attempt to use the Molex connectors.

    EDIT: Found a 6-pin cable that connects to my PSU. Solved!
