The psu will be fine for that video card. However if the card (you didn't mention which brand or model) needs 2x6pin pci-e connector you'll need to use the molex to pci-e adaptor that comes with the card for the second pci-e connection.
You'll need 2 free molex connectors for the adaptor.
Well of course cooler master calculator is going to suggest you one of their branded PSU's lol however i highly suggest you don't even consider that hunk of junk i wouldn't put it in one of my rigs even if i got it free i would take it straight out to my trash can seriously!
