HD 2400xt power requirements

[quizzelbuck]

I am building an ITX HTPC. It has tiny PSU with a lower output then a desktop PSU. Now i needs me a HD card for it. I was thinking the 2400pro or XT if i can get away with it since they decode 1080p stuff all the way up to blueray or VC-1. What is a good place to find power needs for GPUs? Ive done rough calculations that look good, but i want to be a little more certain.

I would say a 350 watts is enough.

Not sure about the 2400XT, but for the 3400 series, a 300w PSU is listed as the minimum, but it doesn't give any amp requirements.

I'd say card itself eats under 35 watts max..

*edit, under 25w http://www.silentpcreview.com/...be5eede2978d2b16972c72

WOO! Thats some good news! i have an ITX board, which is really low power, with a 120 watt PSU. This card, assumeing these power reqs are true, ought to actually pull juuuuuuuust under 100 watts on my PSU. Thats pushing it, but it ought to suffice. Im rather pleased with this finding! thanks for pointing me at that. Ill have to poke around for some more indepth statistics, but that response sure does make me worry less about this.
