That requires a 12 volt input, so you would normally use an external 
brick....exactly like I have on my Zotac ION. The PicoPS is a very neat 
solution, especially if you already have a 12 supply (car, boat etc).
And of course, a power brick is silent, and needs no cooling and lasts 
'forever'. I think I have some which are over 5 years old from my 
Thinkpad(s).
