i update my post as well.
the answer is theortically yes.
if you look at his aida64 pic, its 21amps, 1.163v, P=IE (pie is easy to remember, but also P=I^2R, but harder to work with) to 24watts.
if you look below on that pic, vrm power is 23 and change watts.
the key to remeber is voltage is a measure of potential, current is a measure of force.
so if you decrease the potential you can gain extra force, if you increase the potential, you have to decrease the force.
so at the wall with a potential of 110, you have less force - 9A where as on the pcie rail, you have less potential and more force.
generally, current will remain stable and the circuit will vary voltage to increase the power output.
you see this in CPUS as well, as your core voltage jumps all over the place changing the power output.
this how old TVs used to be able to generate massive voltages in the 10,000v range to run the tubes, with very low current.
the problem is we are used to seeing current rated at the wall in the 500ma-15 amp range with wall-warts, and kitchen appliances, so we see 20A and were like damn, my breaker is only rated for 15A.
