G80 De-Mystified; GeForce 8800GTX/GT

[ANP !!!]

How much power Will this Tower really Eat up ?? They Say 300w, But i seriously doubt it. If yes, then they would fry like hell. Cant say about the R600 since they will be very hot. Will my OCZ 700w be fine powering 8800GTX.


Also was wondering, since this Card IS SUPPOSED TO BE VERY LONG, how long will be R600, (ATI say they will be the biggest Cards ever) OMG.

Your psu should handle one at least. Quad Sli might not work though

I doubt they would try quad again.. That whole project was doomed from the start. Direct3D games see little benefit over SLI, since typically only triple buffering. No limitation on buffers in OpenGL, but then again, not many games either. Quad SLI is just way too impractical, and inefficient.

However, even SLI G80 will surely be big burden. That's probably where they came up with the 250-300W figures. But, also remember you need at least 100-150W for the rest of the system, as well as demand response, and margin for stability. All of a sudden 500W+ PSU requirement doesn't sound crazy anymore.

And one other important thing.. heat. And not just the challenge of cooling G80 (dual slot heatsink or aftermarket water cooling). G80 SLI will surely stress other components too. Some special applications may generate huge PCIE bandwidth load. Chipset probably hotter than ever. Likewise, more CPU-limted scenarios, and more stress on the CPU. If PCIE slot is relied on for power, significant strain there too. And ofcourse, with nearly 500W total being used by the system, even an efficient 80% 500W powersupply will be putting out nearly 100W of heat, all by itself.
