Is an HD 2600 Pro going to kill my HTPC?

[Golgatha]

So I ordered an HD 2600 Pro for my HTPC and looked at the power requirements on ATI's website. They state 400w power supply required. I have an Earthwatts 380w that only has 17A on each rail, which is 204w total to run my system.

I have a single optical and hard drive, overclocked Intel E2160@3.0Ghz, PCI Firewire expansion card, Voodoo 4 4500 32MB PCI video card, and I will add in the HD 2600 Pro once it arrives.

I couldn't find any information from a Google search in regards to total system power consumption with a 2600 Pro, so has anyone here setup anything similar or even beefier than what I have with an Earthwatts 380w with good results?

Edit: I'm hoping to have an abomination of hardware that will retro game and be a HTPC powerhouse by dual booting Win2k and Windows Vista Home Premium 64bit.

My HD 2600XT runs on a 300W PSU with 18A on the 12V rail,card companies throw PSU requirments out of proportions.

No worries. Peak draw is < 31W (or substantially < 3A).

Earthwatts is fine for that card

Awesome. Thanks for the replies. It's in the mail today and it's just in time for Vista SP1 64bit, which I downloaded last night. Now to see if I can convince my neighbor to hook up my HTPC to his 50in LCD to play Transformers on HD DVD.
