With two 8800 GTS's in SLI with my current config it calculated it to be 434W (seems a bit low?). On Newegg's spec page for the 9800 GX2, it read that it requires a 580W power supply. I should be fine on the PSU front.
I wouldnt listen to that caculator, it really doesnt work well at all.

The specs on the card suggests a 580W power supply. I have a 610W continuous with a peak of 670W. I should be in the ball park with this one.

Also, does any one know where to get a 8 pin PCI-E adapter? I can't seem to find one on Newegg.

According to the review on Tom's Hardware, it should.

Oh, and I found that pin adapter. Never mind about that.

Thanks.

From Tom's hardware

"When it comes to global power consumption, the system doesn't seem to need more than 350 W (meaning 300 W for the configuration itself once we subtract power supply losses). Nvidia recommends a power supply with a minimum rating of 580 W, but we consider this to be overkill. Even when future games are able to make better use of quad-core processors and graphic cards, a reliable PSU that delivers a constant 450 W should be more than adequate."

Also, the PC Power & Cooling PSUs are quite strong relative to their rated wattage.

According to one of the reviewers of the 9800GX2 they said:
  • A single GeForce 9800 GX2 requires you to have a 550 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total) at least 35 Amps available on the 12 volts rails.
  • A second GeForce 9800 GX2 installed is another ballgame though; on this system it requires you to have a 750 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total) at least 45 Amps available on the 12 volts rails.

I have more than the suggested wattage and like all PC Power PSU's mine has a single 12 Volt rail. My power supply can handle it easily. The thing is, is the video card actually worth 600 bucks? A lot of benchmarks I have seen show the GX2 is really not worth 600 bucks (at least to me). Maybe when they release the new drivers it will justify buying one. But for now, I'll stick with my 8800 GT.
