#A1200 Power?
It's the Volts, not the Amps, that you need to worry about.
The only problem is that the voltage levels on some poorly designed power
supplies will go up as the load (current drain) drops. (ie: a machine that
draws less power, like the 1200, might not put enough of a load on the PS,
and the voltages could rise because of that, causing problems.)
Just my $.02,
