You could get a small PSU and have it inside the NES, and if its a DC/DC one, have a computer PSU providing the 12v. You might be able to use an Xbox PSU, its pretty small and takes wall power.

Its a really small DC/DC converter, sometimes just a board connected to the ATX connector. You need an external AC/DC power supply for it to give it 12v, a desktop's PSU is the cheapest one I know of that can provide enough amps.

would a charger for a lapop work as the AC/DC power supply? or is a pc's psu an ac/dc? im looking for something thats external that can attack to the pico psu

btw: the board im using isnt a fully micro ITX, but it measures smaller than the nes case

I don't think the laptop charger could handle the amps, the guy in your link used an 80w PSU, which is 5A at 16v (I think most laptop chargers are 16v <4A) or 6.6A at 12v. You probably won't need all of that power, but better safe than sorry.

EDIT: Just checked my laptop's adapter, its rated to 4.5A at 16v, so if you use a similar one, it might work, if the PicoPSU can handle 16v. I'd still just use a desktop's PSU.

Edited my post, but wasn't fast enough, so look up.

Any computer PSU that can output at least 7A on the 12v line should work, you could get an used one for a few bucks.

I think the picoPSU just takes a 12v input, so you'd just wire it to +12v and ground (usually yellow and black, respectively). Then to turn on the PSU, you need to jump the power-on line to ground, usually its a green wire about in the middle of the ATX connector.
