Quick question...On a Radeon 9700, it's supposed to have it's own hookup to the systems psu, but I dont have the power cable that came with the card. Can I buy another one of these somewhere? or is it completely necessary? Didnt know if I could just hook it up directly through one of the psu's existing floppy connectors. (Might sound like a dumb question but last card I had was an old 32mb card, so this is all new to me). Thanks.
