hmm about 30 mins ago i walked away from bestbuy a proud owner of a radeon 9800 pro, i go home i install it and i hook up my computer, everything is working fine and running smoothly untill i turn on a demo the GFX card cd had, about couple secs into the demo my computer shuts down and well, dosent turn on again, looking back im tracing the problem to my powersupply burning out (since i have 2 cd rom drives and 2 hard drives ontop of the new 9800 pro, it had to have given out sometime i guess) i am unclear of how to figure out the wattage my powersupply provides, also i do not even know how to tell if the powersupply was actualy the thing that broke, can anyone confirm the problem befor i go out and pay bestbuy couple hundred bux just to tell me i have connected powercords incorectly or something..
