No graphics card pulls 300W
@ 2006/11/17Now, the highest-end graphics boards can pull a maximum of 75 Watts from the motherboard via the PCIe x16 slot, and every 6-pin PEG power connector will yield additional 75 Watts. So, in case of 8800GTX and R600XTX, we are talking about 75+75+75 = 225, or a maximum of 225 Watts. This is the maximum amount of power that will be eaten and dissipated by an Nvidia G80 and AMD R600 based product.
