So the CPU and RAM runs on 2V or less. Why not use the 3.3V line?
Does the USB even use the 5V line?
One reason is the current would be much higher on the 3.3V line requiring very thick wires or many more.
wouldn't it be less current with more volts?
let's say the cpu is 95watts.
if we ran 95 volts to it, it would only use 1 amp.
if we ran 1 volt to it, it would need 95 amps.
Exactly. The CPU gets its power from the +12V line.

So, it would be safe to assume the mother board uses Voltage regulators to step down the voltage?
Wouldn't that create a lot of heat? Why not use the 12V for everything?
I know, I'm being a pain but my PC Power and Cooling 750Watt is on its way out (random reboots/lockups). It lasted over 7 years and when it's replaced, I'd like to know I pick a replacement that will allow it to grow into a new system and last another 7 years.

I highly doubt anything these days will last 7 years. it might but they just are not designed to last. Every component is designed to be specd for tolerences and to work a short period. It is all done on purpose and also cost. Saving cents here and there adds up to a few bucks overall.. It is nothing like a decade or two ago. I bet there are computers thats 20-30 years old still working. I doubt you will find a 2010 phone or laptop working in 2020 let alone 2030.
