I always had good luck with antec last power supply i had from them was a Antec TPII-550EPS12V TruePower 2.0 550W EPS12V
+12V Combined Output: 54 Amps (62 Amps, 744 Watts, Peak)
Weight: 8 lbs.
A mans PSU.
Most PSU's over exaggerate their specs, which is sad. And misleading to me.

Exactly. Dual rail would have major problems with SLI or Crossfire, with only one 15-18A rail driving both cards.
lets look at matters this way. An X1900XTX card supposedly pulls about a maximum of 120-130 watts. Now W=V*A, A=W/V, and V=W/A
So Amps equals Watts divided by Volts.
130.0 watts divided by 12.00 volts = 10.83 amps
Now lets say you have a fairly standard AMD system (Say a OC'ed single core processor to 2.5Ghz, 2 Harddrives, DVD burner, Motherboard, and some case fans) at best your 12v line usage would probably never exceed 15-17 amps.
So a rough estimate for the maximum number of amps that system would ever need on the 12v line is about 27. I think my math may be a little high but it ought to be fairly close.

OP = Owned? After all these responses, he hasn't replied at all.
Enermax 495W w/36A combined on rails.

It's like he posted straight outta 2004 lol
Antec TruePower II 480w. I love it - so silent. Expect it can handle an X1900XT just fine.

20a is weak.
this $30 fsp 350w non overpriced bluestorm will provide 30a and it will be stable too.

Like most, they show the max output, which is 350w. I have doubts that will hold up with a XTX, 2gigs of ram, HD, Rom, dual core CPU, etc. Its a piece of crap, and it would be very shortsighted to put such a PSU, with a top end card and system.
um.. it's a fsp, fortron, the 2nd most highly regarded psu in the business after pc&p.
I doubt FSP will screw you over and scam you. POS it is not. FSP has a track record for quality products and I cannot see why they would put out a pos to sully their very good name. That's like Lamborghini or Ferrari taking a daewoo and selling it.
besides they show max sustainable output(meaning you can do that power rating for however long you want and it'll be stable), instead of max peak output like other companies.
from guru3d, results are from the plug, not actual dc output.
Graphics card.......100% load...System Idle
X1300 XT............193.............133
X1600 XT.............211.............140
X1800 XL.............229.............155

X1900 XTX ..........290.............165
Mainboard
Gigabyte GA-K8NXP-SLI motherboard, nForce4 SLI, Socket 939
Processor
AMD Athlon 64 FX-57 +, Socket 939
Memory
2048 MB (2x1024MB) DDR1 - PC-3200 2-3-2-6
Drives:
DVD rom, HDD
edit: a;so, fsp's watt rating is weird.
the 550w unit has the exact same output as the 450w unit for half the price(36A +12v, 3 more amps for 450w on +3.3, 1 more amp on +5v for 550w.).
the 350w unit has just a little bit less trhan the 450w unit for 60% the price(30a v.s. 36a)
In your opinion. I dont think it would run what I said, stable. And I sure wouldnt trust a $30 PSU with $2000 of gear.

Hiper Type-R 580W Modular PSU here, should cope with every card available today.
+12V1 = 20A
+12V2 = 18A
+12V1 = 20A
+12V2 = 18A

how about seasonic s12 600w?!
the fact is, there are many psu that would be able to satisfy the recommended specs
heck, even my old antec neopower 480w would

brand. pc&p is supposed to be higher quality.
To a point yest they are higher quality but they are still overrated and overpriced. The FSP is 98% as high the build quality for half the price, but some people like no compromise, like those running cas2 dd500 ram on amd64s, the pc&p has a niche of people that either need the highest quality rail regulation for whaever price, or just have money to burn and want to brag about the brand name.
For most people, though the FSP 450w will do everytrhing the pc&p can do at 1/4 the price.
The FSP 600w you linked to will be better than the Pc&P and od much more, but it dosent have the brand name. It's like a Chevy Corvette Z06 v.s. a Porsche 911/Ferrair 360 Modena. The corvette dose much more and does it just as well, but it dosent have the brand name so it costs less.
If I was buying a PSU today, I would get this:
http://www.newegg.com/Product/Product.asp?Item=N82E16817103478
It has the FSP build quality, a single hefty 36A 12V line (which I would definitely prefer over two weaker rails) and a low price (it's available as low as $80 at other places). There is also a newer SLI version for a few dollars more. I don't think you can beat the performance for the price here.

OCZ PS 520W (http://www.newegg.com/Product/Product.asp?Item=N82E16817711002)
I think that would be sufficient . . .

See, that's odd, since my S12-600 is driving 2 512MB GTXs. Wrong info, bud.
