My brother just got a PNY 6800 for Christmas and this thing just seems to want way too much power. With 2 separate PSU's, each 420W w/ 18A on the +12V rail, (a Turbolink and a no-name), I got the infamous loud beep of death as soon as I plugged the PSU into the wall (and yes, the auxillary molex was connected properly). As far as I know, this means the thing just isn't getting enough power. By the way, the only things plugged in were the motherboard and video card. So I dragged my rig over and tried it with my Antec 480W NeoPower PSU and sure enough no beep. My question is, are the 6800's really THAT power hungry or is there something wrong with the card. I know all of the issues associated with "unclean" power but this just seems excessive. Anybody else had similar experiences?
