I just got the Asus G-force fx5950 ultra. After i put it in and fired my comp up it said it wasnt running at top speed cause of a lack of power. I have a Thermaltake Silent Purepower 480W power supply. What i am trying to ask is it that messege coming up really mean i have a lack of power or is it just a diver issue.
my Comp specs if ya need them are

asus a7n8x deluxe MB
amd xp 2800
Gfroce fx 5950 ultra
512 Corsair XMS 400mhz DDR ram

If any of you guys could give me some imput it would be great thank you

No clue, but if you can't run a FX5950 with that power supply, what good is the card? Just hard to imagine "needing' more power than a name brand 480watt.

ABIT IS7, P4 2.6C, 512MB Corsair TwinX PC3200LL, Radeon 9500 Pro, Santa Cruz, Antec 1000AMG, TruePower 430watt

I was having a "power" issue with my GeForce 5900 (non-ultra) and managed to get it solved. I never got the message saying that my card was underpowered, however the voltages from the power supply were varying to the point that when the card revved up to 400 mhz for 3d applications, it would crash, or just quit back to the desktop. I thought a 430 watt Antec TruePower supply was enough for what I was running, but apparently 3 hard drives, 2 optical drives, a 2800 Barton, 2 512 MB DDR333 sticks of ram, a Nvidia 2 MCP-T mobo, a soundcard, a Koolance EXOS water cooler, and 4 fans, not to mention the graphics card, is too much. My solution, after several good suggestions from people in this forum, was to add another power supply to my system. I added a separate 300 watt no-name power supply which now runs all of my fans, my hard-drives, (i will be running my optical drives off of it soon as well), and my Koolance EXOS. After that change my system was relatively stable. I then boosted the voltages to my RAM to 2.77 volts up from 2.63 volts, and also increased my AGP voltage up by 0.1 volts. This seems to have stabilized everything in my system except for my CPU frequency, which according to 3d mark 2001 SE and PC Mark 04, ranges at various times from 1.885 GHz to its normal speed of 2.088 GHz. Hope this helps.
