It is rated at 100 wpc.
However, the review of the 27 (not the 27.5), stated that it measured closer to 140 wpc before they clipped.) This is based on my memory of the review that I read a few months ago, before I sold my 27. (Funny enough, I sold it to a guy who was going to use it with the B&W 801s. If I could remember his name, I would pass it on, but I can't as it was a year or more ago. Sorry. I never heard a complaint from him, so I "guess" it worked ok. I would think more power would be better, but then again, isn't that almost always the case?)
Hope this helps.
