3GHz P4 Requires New Powersupply

The word from motherboard makers is that the 3GHz Pentium 4 will require a 70W onboard power supply, which means that current motherboard designs are not compatible with the new processor.

"Requiring 70W power supplies, the new P4 processor is incompatible with present motherboards, which only support the 60W standard, board manufacturers said. For the technology update, companies need to change the on-board PWN (pulse width modulation) controller IC design from three-phase mode to four-phase. In addition, to pack in an increased number of components, board makers have to rearrange the circuit layouts as well."
