Amp for use with Daphile

I have a Daphile box with multiple audio cards and plan to assign each card to a room for whole home audio. I've been looking for amps and came across this:
Amplifier Board TPA3116D2 50Wx2+100W 2.1 Channel Digital Subwoofer Power X1B4

Does anyone have an experience with these? Also, what size power supply should it be paired with? 200w?
