I'm looking for a high power efficiency PoE switch, which is something the switch manufacturers don't seem to emphasize in their marketing. I'm thinking something along the lines of a 90+ Titanium Power supply efficiency - ~95% efficient at 50% load. I'd be looking at something around a 12 port switch with 8w / port.

The reason I'm looking for something high power efficiency is that I'm running distributed computing on a stack of raspberry pis. See below for a thread on the topic:

Generally speaking, the cell phone power supplies suck when it comes to power efficiency and are anywhere from 65% to 80% efficient. Raspberry Pis have the possibility to be the most efficient way to run these projects on a per watt basis, but realistically its going to require higher efficiency power supplies than what you can buy from cell phone chargers. I'm thinking a PoE switch may be the way to go, if someone makes a high efficiency one, AND it isn't so expensive that I might as well go buy another 5950 and put it in eco mode.

Thoughts and suggestions?

I don't know what that is, what your budget is or what is or isn't considered efficient, but I'm using two POE switches that provide 4 POE ports and two standard ports. They use a simple wall wart and one is powering a camera about 120 cable feet downstream and an access control device about 150 cable feet downstream without issue. The other powers two cameras not as distant.

Price was in the $20-30 range for each.
