Cool thanks for the calculation method.
I've got my CPU wattage ouptout. It's rated at 67W full load not overclocked. But I have it overclocked and I'm currently on air to 1950mhz. So I'm not sure how much more heat and wattage it's making. Also I haven't unlocked my chip yet, which happens to be an AMD XP 1600+ AGOIA stepping. I will be pumping more voltage in this unit but not just yet as I'll be upgrading the mobo, ram, and video card.
The upgrades will be an Abit NSF-7 v2.0 mobo, 2GB OCZ PC3200 ram, and an eVGA 6800GS video card.
I still have a bit more numbers to run though.
