BAT REX power consumption


I'm considering moving to a BAT REX, but have some concerns regarding the power consumption. The specs indicate 470 watts total between the power supply and main chassis. Even the 52SE puts out 250 watts. I don't think I've seen any preamp putting out more than 100 watts, with most consuming considerably less. Is this something, outside of increasing one's electric bills, to be concerned about?

Hi Victor,
If the REX power module is putting out typically 155 watts, what is the main chassis' output at the same time?
Thanks for the clarification, Victor. My question to you must have been unclear, since I was looking for average power consumption.

300 watts or so is still a fair bit of heat from a Preamp, but right now that would be welcome.

My mono blocks draw a constant 820 watts/pair & I still need a sweater (it's 3 degrees here).
