1 or 2 Molex to 6-pin PCI-e

Hello,

I recently purchased a suggested build on pcpartpicker.com, and I assembled the entire thing before realizing that my video card requires external power not supplied by the motherboard. The suggested power supply has no 6-pin PCI-e cable, but has multiple open 4-pin Molex connectors. I'm wondering if purchasing a Molex to 6-pin PCI-e would be a viable option for my situation, and whether or not the cable should connect to one or two Molex connectors. Here are the video card and PSU that I purchased:

And here are the cords that I was looking at:

Thanks for your help!

    2xMolex to 6pin works just fine, but in your case I highly recommend that you buy at least a quality 450W PSU. 350W is not powerful enough for today's GPU's, which probably explains why it doesn't even include a dedicated 6pin.
  2. Thanks, Herr_Koos. I'm mostly just frustrated because I assumed that, as it was a recommended build, that issues like this would have been taken into account. I guess I'll look into returning this PSU and getting at least a 450W replacement.
  3. Cool. Seasonic is a decent brand from what I hear, but I can also recommend Antec, Corsair, Thermaltake and OCZ.
  4. I think you'd be ok adding an adapter as long as you don't oc your cpu and gpu.
    If you plan to tweak that stuff go for an upgrade.
