what power supply for Ati 1950xtx

[xtera]

I got a echostar 580 watts. What power supply do I need to get Im finding it
hard to get it to function even when i bought a 500watts but that one I
tried to replace it with is not near the power of my existing supply so I
think i need more than 580wats so I know Im close in amps . What are u guys
recommend I get Ive been thinking I should get a thematake 600 watt or
better the one difference I can tell is the 12volt rails do they use more
than one rail I think mine is spliting th amps to all the rails so its
sharing the load of the 19amps I see for my 12volt rail . I dont show in on
mine i dont see 19amps 3 tims for 12volt rail >>>

current config
Asus P5NSLI

ATI say minimum of 30Amps on the 12Volt rail for a fully loaded system is
recommended.
The Echostar doesn't provide that but the Thermaltake does.
