How to determine the power consumption of your amplifier. The most power that any amp will ever draw is the AC line voltage multiplied by the amplifier's fuse value and even then, it is unlikely to ever reach its maximum level. For example, in the …
Power Amplifiers Power Consumption - diyAudio

Standard test conditions for power consumption in amplifiers is at 1/8 power with pink noise - not full sine wave. It's approximately what the amp draws when playing music with clipping just audible. Expect about 2X that with the amp "blasted".

The maximum amount of power it can draw would be limited by that. If your AC is 120v then multiply that by 1 amp to get 120 watts. Under normal operation it may vary from 2-5 watts up to maybe 100...
Power Consumption of Hifi Amplifiers - HydrogenAud

There's always a lot of talk about how big and powerful an amplifier needs to be to be as big and powerful as we need them to be. How big and powerful is that? Well, in fact the average power consumption in the home is less than 1wpc, such as when playing at around 75 or 80 dB, which is quite a bit below 1 watt.
Some observations about amplifier power consumption ...

What an amplifier will say at the back is Maximum Power Consumption of xxx Watts. What this means is that the amp MAY draw an maximum current of xxx Watts from the power supply. Power consumption is used not only by the audio generated by the amplifier, but also by the heat generated.
amplifier power consumption - High-End Audio Discussion Forum
https://forum.audiogon.com/discussions/amplifier-power-consumption
I would be hesitant to use even the 540W ups, without knowing the exact power requirements of your particular amp. Here is a Cambridge integrated amp rated 75W/channel and spec'd for a maximum power consumption of 600W. Here is a Creek integrated amp rated at 80W/channel and spec'd for 340W consumption at full power. So the numbers can vary widely.
Receiver Power Consumption Rating vs Output Power Is …

The Parasound NewClassic 2250 v.2 stereo power amplifier from 2020 shows an AC power consumption of 1000 watts (maximum) and is spec’d at 250 wpc @ 8 ohms, 400wpc @ 4 ohms, ACD, 20-20kHz. That will be a 1.6:1 consumption-to-output ratio (1000/550 = 1.8 for 8 ohms and 1000/800 = 1.3 for 4 ohm loads.)

Doodski. My speakers are bi-amped with two Class D power amplifiers rated at 60 watts per channel (each stereo power amplifier). They use Texas Instruments Class D modules. The power switches are inconveniently located at the back of each power amplifier.
How Much Amplifier Power | Crown Audio - Professional ...

If you are playing light dance music, the amplifier's 4-ohm power should be 1.6 x 100 W or 160 W continuous per channel. To handle heavy metal/grunge, the amplifier's 4-ohm power should be 2.5 x 100 W or 250 W continuous per channel. If you use much more power, you are likely to damage the speaker by forcing the speaker cone to its limits.
