Should be enough as each PCI-E probably has it's own 18A 12v rail. I thought you sold that 8800 Ultra ??

Re: XFX 8800 Ultra Recommended PSU

I reckon it'll even run on my $55 Coolermaster 430W PSU without any problems. (look at my sig. LOL)
That Antec PSU can run two of them in SLI and still have plenty of power left. What's the worry? =P

BTW, Each 8800 Ultra uses about 150watts (13A) total under load. Up to 180W (15A) if overclocked.
My overclocked 8800GTS uses around 120watts. (10A) Not a huge amount of difference is there? hehe.

Re: XFX 8800 Ultra Recommended PSU

Just for kicks I put a 8800GTX, Commando, E6600 @ 4K MHz with 3 drives, all overclocked using a 32AMP 12V rail PSU and it was all fine. I have however tried a lower amperage PSU and got a message stating that the GPU was in low power mode.

Saying that, there is no substitute for a good PSU
