Default Recomendations for a 600w+ PSU

I really want the 700w OCZ PSU, but on newegg.com, it lists only 18amps comming out of the 12v rails.
My two 7900 GTXs need 22 amps.
I can't seem to find any PSUs with 22 amps. Does anyone know of any 600w and up PSUs that have 22amps on the video card lines?

The PC Power and Cooling Silencer has 60 Total Amps For 199.99$.
Pretty good If You ask me...
Ill look for more.

The 610 Watt Version has 49 total Amps For only 159.99$

The Enermax Liberty 620 Watt Has 22 Amps Per Rail. Total of 44 Amps. For Only 159.99$.

Whats your Price Range? Its doubtful that youll find a quality PSU with high Amperage on the 12V rails for much less then I am finding.. The Reason for this is because: As you know Volts X Amps == Watts Therefore More Amps will Equate to higher wattage Power supplies, which in turn are more expensive.

Please keep in mind that Dual 12V rails IS NOT a requirement. (Unless Video card specifications state otherwise)
Also It would help if you listed the Other Components.

U lookin at the GameXstream OCZ? if so, its 18A comin out of 4 12V rails as compared to most PSUs have 2 12V rails. The GameXstream (600W or 700W) will have enough power for ur 7900Gtxs

Yes, I was looking at the gamexstream. I'm willing to spend up to $170 for a PSU that will properly run my system. I currently have: http://www.newegg.com/Product/Produc...82E16817194001
but was toldit doesn't have enough amps for my cards.

It does. 44 Total Amps, Spread Across two Rails at 22 Amps Each.
If its 22 Amps PER CARD By themselves then youll want to look into one I linked or Look for one with four Rails @ 18 Amps Each.
Heres a good Review for the OCZ 700 Watt.
http://www.jonnyguru.com/PSU/GameXStream700/
Btw the total Amperage is only 56.66 Amps and not 72 Amps.
Because 680 Watt Divide by 12 Volts == 56.66 Amps. Therefore each rail is capable of putting out 18 Amps but not all at the same time. Continious is only 14.165 Amps.
