    I just received a new ATI HD5850 videocard, not realizing that it would require two power connections. My Antec 650W PSU has only one dedicated video power line (6 + 2). I just want to check with folks who know more about things than I do to make sure that 1) there is no problem using just the 6-pin connector and leaving the 2-pin hanging loose, and 2) there is no problem with using a 4-pin molex (using two of them) to 6-pin video adapter to produce the second power connection for the video card. I cannot see any reason why there would be a problem with this scenario, but I have also fiddled with computers enough to know that I am a complete novice and can certainly not know something that could bit me in the ass [which has happened more than a few times ;-) ].

    Thanks in advance for your advice,

    Use the 6 pin power connector. No problem with the 2 pin power connector hanging loose.
    You should be able to get by with your PSU, SLI would be pushing it though.
    Invest a little time and energy in a well thought out BACKUP regimen and you will have minimal down time, and headache.

    Hi Stuart,

    In response to your 2nd point, are you thinking of using an adapter such as this one from NewEgg ? If so, that should work out fine for your card.
