What's the power line?

[Erupter]

I'd like to know where does the cpu take its power from, as to say from which line (3,3V ; 12V ; 5V)of the psu.
I hope someone does know this.

On virtually all modern systems, the CPU is not powered directly from the main PSU. Instead a seperate power supply module is built into the motherboard.

With the exception of Pentium 4 systems, most PCs power these regulators with +5V. Because Pentium 4 CPUs need so much power the regulators are designed to use +12V.

Ok, so (if I remember well) for 70w (a Tbird 1400) it's 14A, right?

Most cpu's run at 1.4 t0 2.5 volts depending on type of cpu.

14 amps?
most vaccum cleaners don't suck that much current
