My computer already has an Nvidia GeForce GTS 250 1GB graphics card by EVGA in it that was installed in the factory where I had it built.

I'll admit I'm somewhat computer component challenged.

I bought a second video card (exactly the same) to put in my other open PCI Express slot in my computer.

When I took it all out of the box today it has a 6 pin PCI Express Power Cable, which in the directions it "highly recommends" connecting it to the power source with the (very short) supplied cable.

The builder used zip ties to make the inside of my machine neat and clean so the closest power I could tell coming from the power supply was about 12" away. Even if I cut the zip ties the cord would never reach them (if in fact these are what I'm supposed to plug this into).

The cable has one black plug which connects to the video card and two white/clear plugs that I assume plug into the plugs coming out of the power supply. Here is the image:



So my two questions are:

1. Am I correct these white/clear plugs plug into the cables coming from the power supply? (If so I can't reach them so have already ordered extensions to help me reach them.)

2. Do both of the white/clear plugs need to be plugged in or just one of them? (There are only two existing male connectors that I can see remaining from my power supply so I'd have to use both.)

Thanks for any advice,

Malgor
