I have a simple question that i think i know the answer to but i am not 100% sure
A computer CPU (mine for example!) is 1.4V and has a TDP (thermal design power) of 67Watts! there is a little example here: Thermal design power - Wikipedia, the free encyclopedia now at that TDP the CPU would be pretty maxed out without some extra cooling options needed to bring the heat down!
So my question is that the CPU uses 1.4Volts to function and it can run at 67Watts before extra cooling is needed...etc basic equation is: 67W/1.4V = ~47Amps! Now that's a lot Amps! or is it more like 12v(the supply rail)-1.4v(the CPU) = 10.6v 67Watts/10.6=6.3Amps i don't know!
Now how does a power supply cope with these amps, does the power supply use the power from the 12V from the 24pin connection as well as other connections like the 12V atx connection, because most power supplies do not produce that many amps per connection! or does it NOT draw that much current? thanks...
