Tags: Graphics Cards Dell Studio Xps Windows Vista Graphics Last response: October 22, 2010 2:22 PM in Graphics & Displays Share anacandor October 22, 2010 1:34:14 PM First up, it's an aging dell xps 420 system, Vista 32 bit Q9550 @2.83 3GB ddr2 9800gt (512mb, the older one, not green) 500Gb wd HD 425W dell PSU (18amps on +12V) 1680x1050 monitor As far as i know dell's psu's are rated differently, and tbh i just got no idea what will fit with it or whether i should grab another psu will im upgrading. Any ideas on the best card for the psu? More about : 6850 work 425w psu skolpo a b U Graphics card October 22, 2010 1:37:37 PM Dell tends to rate their PSUs lower than they really are. It looks like the HD 6850 draws about 260W at load (full system). You shouldn't have any problems running the card on a 425W PSU. anacandor October 22, 2010 1:46:01 PM skolpo said:Dell tends to rate their PSUs lower than they really are.

Thanks for the reply, and just out of curiosity, could it push a faster card than the 6850?

Just stick with the HD 6850. You can't go wrong with that. anacandor October 22, 2010 1:56:28 PM Best answer selected by Anacandor. anacandor October 22, 2010 1:59:33 PM love your work skolpo, exactly what i needed to hear Mousemonkey a c 264 U Graphics card October 22, 2010 2:22:30 PM This topic has been closed by Mousemonkey Can't find your answer ?
