A computer power supply does nothing more than convert your AC electricity into DC.
Power is power (measured in watts), whether it is AC or DC...so if the specs of a PSU are something like 10A @ 120VAC (or 110V whichever you prefer to use) then you have available 1200 watts of POWER (120*10) when you convert it to 12VDC for example you would have 100A @ 12VDC because you have to balance the equation (120*10 = 12*100)...that is in a perfect world...the conversion process will make the right side of the equation a lower number due to loss in the circuits, etc. If we convert the AC to 24VDC the equation would be (120*10 = 24*50).

Your reference to fire hoses earlier......if I have 2 hoses flowing 80gal per min each.....how many gallons per minute will I be dumping on the ground ? ..... I believe your answer would be 80 but there is no way that is correct...the answer is 160 gals per min would be flowing onto the ground or into whatever I want to put it in. How could you possibly say I would only get 80 gal per min from 2 hoses?????????? Each hose would fill an 80 gal cont in 1 min....therefore at the end of that min I would have 160 gals of water...right????

With that said.....VOLTAGE is the "pressure" in an electrical circuit....AMPERAGE is the "volume"....not the other way around....if you find one of those books about electricity...you will find that exact reference.
So back to the fire hoses.....if hose 1 is at 100 psi....and hose 2 is at 200 psi...both flowing 80 gal per min.....which one has more power??? ding ding ding....hose 2 does because it has twice as much pressure at the same flow rate which leads me into .....circuit A = 120V @ 10A vs circuit B = 240V @ 10A ...which has more POWER (watts).....Cicuit B does because 240*10 = 2400 vs 120*10 = 1200.
I hope this clears up some misinformation given in this thread.
