New card needs two six pins, power supply only has one and a couple molexes open

The card came with a couple of adapters for the molexes, the problem is the two open are on a triple connection that's currently using one to power my hard drive.

The video card needs two 75W six-pin connections, so I guess the real question is will a triple molex be able to supply one 75W connection and whatever the hell my hard drive needs? Generally speaking, I know I'm drowning you guys in specifics here.

Oh, found the specs for the drive... it's a Western Digital Caviar Blue, WD5000AAKS

If I'm reading it right, it's going to need about 5.6W on average for its peak use?

    Hi - What is the brand/model of your PSU? I suspect you probably don't have a good enough PSU
    to power that system. However, list the PSU brand/model in order to find out one way or another.

    Ha, yes, I ended up pulling it out to find it's only 450W, leaving me a bit short, thought I'd had a 500W. One overcompensating trip to a part store later and the problem is solved in a new 750W with all kinds of neato connections.

    Would still be interested to know if, assuming the supply had the wattage required in the first place, that would have worked.
