GRAPHICS CARDS ARE constantly demanding more and more juice, and the levels at we are looking now are pretty much unbelievable. While the microprocessor industry learned its lesson about bleeding power like a stuck pig, the graphics boys are still living in a dream bubble that power levels won't be reached. Since 80nm and 65nm graphics chips are approaching fast, there is general concern how much power next generation graphics chips consume, given the fact that the PCIe Gen2 standard will give an additional 75W, or 75x4 = 300W. If you want a multiple graphics chip configuration, you will require at least 1000 Watts at 85% efficiency.
Engineers at ULTRA and OCZ Technology worked hard on this conundrum and the final results are being launched this CES. Forget about 1K or 1100 Watt power supplies, 2000 watts is now the measure of brutal power for computer components. So these power supply units (PSUs_ have power spec equal to small air-conditioning units and just mention that the approach of these two companies is totally different
