420 watt of power enough for future ati graphics card

hey

im currently running on a socket 939 and i want to upgrade to a amd athlon 64 x2 4800+ and one of the ati graphics cards that will soon be released before saving up for a new rig (lets hope in like 1-2 years). would my 420 watt power supply be enough to do this?

thanx in advance 

No, get at least 550Wuwouldliketokno

i have a atx 12 V power

an 8800 gts 320 mb says 26 A is minimum

i dont have 12v 2.0 by the way

i think i need a new power supply that will power dx10 games and allow me to overclock. any suggestions?

well the PSU is the heart of the system.  I never go lower then the best for a PSU.

Ya know, I've been wondering the same thing - I'll be upgrading to the new ATI 2900XT, but the power requirements seem to be rediculous.

My current setup is a 550W Neo HE, which is manuafactured by Seasonic. I'm running a E6600@3.3, 7 case fans, 2 HDD's... all of that, running at the 100% would probably use about 210w I'd guess. So, if the 2900XT has a max usage of 240 or less, I should be fine.  Normally I'd just replace the PSU, but this thing was pretty pricey back when I bought it... and it's extremely high quality and I'd hate to have to replace it so soon.

So, here's hoping my current PSU makes it through another round of upgrades. Do you all have any updated info on this? I should be fine with my current PSU, shouldn't I?

You just gotta know.

It the HD2900xt will be using under 200w.
I  would say a minimum of 500w, with a about 35amps on the +12v rail.

you dont thinka nice 420wt PSU could do it?  If the system didnt have an overclock on it.

Probably, if it can output about 400w on the +12v rail.
