Graphics My PSU won't let my X1950XTX breathe ~ help ~

I got my spankin new X1950XTX in the mail today sadly only to find it's pushing my power supply out the window . Requiring 30 amps on a 12v rail is a little more than my puny 17amp rail can dish out.....

I loaded up my rig thinking it was going fine, but it restarts into a black death after the Windows loading screen.........
Can anyone tell me whether there is some way around this, and if not maybe a good 600 Watter or so that can handle all I have and maybe a future upgrade or two? Somethin with a decent rep and at least a 30amp 12v rail or two (550 or lower should be fine as long as they have real nice 12v's[30amps or higher]). I would do it myself, but know nothing about power supplies(other than what I learned today) nor how to tell the good ones from the bad and the ugly.....

My specs -

AMD 3700+ (2.2Ghz)
2Gb (4x512) Corsair XMS, DDR400 PC3200
ATI X1950XTX (2Ghz memory clock XD )
EVGA nForce 4 SLI mobo
300Gb Maxtor HDD
UltraX2 550W PSU

All the other gizmo's as well - 2 smaller hdd's, 2 DVD-RW's, army of fans, and 2 Cold Cathodes.

ANY help would be much appreciated, till then I can't touch my oh so very sweet new card......

 

Anything from Enermax (my favourite), or from Antec, OCZ, Seasonic, PC Power&Cooling or Tagan that is rated at 500W+ should be fine.

 

^ What he said.

Must suck the fat one having that card sitting there lookin pretty but not being able to use it!

 

I would get, and prob am getting, the Corsair HX620 with "triple 12V Rails provide independent reliable power to the CPU, video card and other components with a combined rating of 50A (40A on 520W) maximum! Advanced circuitry design that automatically enables power sharing between the triple +12V rails in an event of overload on any single +12V rail."

That will most certainly do the trick.

 

People are reccommending I buy a 700w-750w brand name PSU that has four 12v rails at 18 amps each. Would this work? From what I understand, if more juice is needed on the 12v rail im using, then its rerouted from the other 12v rails. Though my current PSU has two 12v rails with 18 amps on each, so why doesn't it reroute from the one im not using to give me the power I need? Is it a feature in newer, better PSU's, or am I missing something?


Also, I found this 520w that has a 35amp 12v rail. Is this enough to run my system and new card, or should I dish out the $150+ for a 700w-750w brand name with four 12v rails, especially with the ddr2 ram, dx10 cards, and all the endless upgrades on the horizon? Don't know if it makes sense, since alot of the new stuff is being made to be alot more power efficient(the new intel procs are a perfect example)......

and Thanks for the suggestion, that Corsair HX620 looks mighty nice, but a tad bit pricey for my taste since for $20-30 less I can get a 750w from OCZ or some other reputable company.......

 

If you want the high end graphics cards you'll need the high end PSU's to go with it. More rails isn't always a good thing, as the power is divided between the multiple rails and only a handfull of PSU's can reroute the power from one rail to another, I know the corsair can as it says so and I have been researching it for my own rig. Have a look at http://www.ati.com/technology/crossfire/buildyourown2.html if they r good enough to run 2 x1900's in crossfire they should be able to run one x1950

 

Thanks alot, both PSU's I was thinking about getting are on that list -

Does the X1950XTX really take twice the power of an x1900? No matter what though, its still a behemoth.

 

power consumption on X1950XTX is higher than X1900XTX, but it's definitely not two-fold.

 

no it dosent i build my system up on a 430watt psu with 10a & 15 amps on the two 12v rails and that ran with no problems at all
ati (his) x1950xtx
core2duo e6600
2gig ddr800 @ 9oomhz
creative x-fi
3 sata2 drives
2x dvd writers
either that or i was extreamly lucky that it was a good quality psu.
i have replaced it today though as i would like to go crossfire
the psu i now have is a seasonic m12 600watt
i know a good psu is expensive but considering the damage a poor psu can do to youre comp i would always advise to get the best u can afford

 

it my recollection antec NEO HE 550 has 4 rails on the 12v rated at around 17-19 amps each i think. I have 500 since i didn't need the 550. They are also very quiet and very effcient (+%80). Just a thought. Also seasonic and PC&C also make great PSU but PC&C is not as effcient as the antec neo HE if my memory serves be correctly (but it has been known to betray me in the past)
