amplifier power consumption


A moment ago, I did a cursory search online to determine approximately how much power, in watts, a typical lower-powered integrated (50-70wpc) draws from an outlet. Didn't find a proper answer. Was wondering if anyone here might happen to know off the top of their head...

I ask b/c i want to buy and use a UPS (uninterruptible power supply) to use for my integrated (Sugden A48b) and was wondering what kind of numbers i would need to adequately supply power to the sugden. There are models that supply 200w, 330w, 450w and i believe one at 540w...

POssible that anyone here knows offhand which would suffice for my amplifier?

I'm going to go surf for more info now... Thanks!
