Which motherboard uses the 8-phase power connectors and supports Core 2 Duo!?
Asus P5W DH has 8 phase power and doesnt have the 2x12V connector for the cpu. It's not really neccesary I think its just a second rail.
Asus P5B Deluxe has the 8 phase power and the 2x12v connector and is by the way one of the best mobos for ocing conroe.
