Couple of questions, I am a hobbist, so please answer if you can simply.

An example of commercial power amp specs...Stereo amp rated at 2100 w RMS/chan, (amp does deliver this output power), 3000 w peak/ch....power consumption, at the mains 240Vac is 630 Watts.

Ques 1. Power consumption is 630 watt @ 240 V ac....doing the maths, power consumption would be approx 240vac x 3.15 A = 630 W (VA), this would be correct?

Ques 2. If I have 2 x amplifier modules rated at 1000 W RMS, 1800 w Peak, +/-100 VDC supply, using same formula, 240vac x 4.16 A = approx 1000 w,

in reality purchasing an after market SMPS power supply, what would I really need, as an example this SMPS specs are as follows, 500 w , 240VAC input, output +/- 65 VDC.......using these specs, is that the actual power it can deliver, or would it be the power consumption, as in the eg: at the very top, where 630W was used.

Or does the manufacturer, stating the power supply specs, but can be used in a power supply for a similar amp to the very top one, what I mean is, power consumption 500 w , using the same ratio of power supply, and 2 x amps (2100w/ch, and 630 total power consumption)......500w power consumption, could power 2 x amp modules rated at approx 1600 w/ ch
