I think you guys overlooked the part about the wattage only being 50 watts on this power supply. You need minimum 60 watts to run and EPIA board and that's the most efficient board out there. What can you power with 50 watts?
The input is actually 6-50 volts rather than 8-50 volts but of course there shouldn't be any problems here.
Now they have two other 60 watt power supplies with 6-40 volt input. But they have UPS built-in and we would have to ask for a quote to get a price. I would guess that they would be pricey.
Here are the links: HESC-104
UPDATE: I was able to find the price of the 50W power supply by reading some of their newletters. The price is $295. I would be afraid to ask what the 60 watt unit would cost. http://www.tri-m.com/news/vol3iss1.pdf
Yeah, these guys are right around the corner from my place, and I have looked into them before. WAYYYYY overpriced. The only thing is, that that was probably Canadian dollar, so for you US people, it would be about 30% cheaper. But still WAY too much.
