unable to help with the psu question, i assume it is...dont hold me to that, consider the x1800xt, cheaper n basically as good as. look at the gpu clock speed and the memory clock speed ;)
 
was thinking..for £30 more get the 1900 as it has 34 more pipelines..thought this was important..?? and the mrs' has let me spend it!!!!
 
I ordered a Connect 3D X1900XT-X last night (512mb) from here OcUK, and have a seasonic S12 psu waiting for it (600 watts 12v rail 18Amp x2)

I read reviews last night on the XT1900's and some were tested on 620 watt psu's (and higher - even as high as 1000watts) with the mention that an XT1900 requires 36 amps on the 12 volt rail???? *** :eek: - if thats so, then I only just made it with my seasonic.

Just looked your PSU up, and details on the 12 volt rails are as thus: "12V 1
16A 12V 2 15A" - so that totals 31 amp - I would say that is good for a 450 wattt - as I've seen similar wattages on psu only have 1 rail with 18 amp. I'd say it would work ok (famous last words :)

Balls to that!

150W/12 = 12.5A.
200W/12 = about 15A.

So its fine.

30A+ is for whole system ampage. I have a S-12 with a C2D + X1900XT-X and I bet its only 60% used.

i dont think the xt needs anywhere near that amount of power
 
This is part of the specsheet re: HPU-4S425

you wasn't confusing the "25" amp with the 2.5 on the +5VSB was you?

Should still be ok, theres ppl powering x1900's on less than 400w. :)

Ive got a GlobalWin SuperSilent 520w, only got 1x 12v rail rated at 20a, powering my x1800 XT 512mb fine, thats including 2x hard drives, 2x DVD drives etc..., and the x1900 won't use much more than the x1800. :)

Yes, but eventually - (like mine did) it could just blow up! (it was a 300 watt running my Current X850XT) And was smack bang in the middle of F.E.A.R. When I opened the case, I saw smoke - lots of it, Quite a good gaming experience really ;)

The "this week only" Connect3D ATI Radeon X1900 XT 256MB at £164 X1900 XT 256MB looks good, I ordered a 512 Meg version as I heard COD (call of duty) is happier with more memory - not sure though....
