I need one of those external power supplies like you see on laptops, with the round fitting at the end that would connect to the DC board in my case. Is there any quality brands that have around 140w or a little more that anyone knows of? This psu is going outside the case, and I have no knowledge at all of any reliable manufacturers of those types of units.

What motherboard do you have? Does it come with the DC jack? What voltage does it need? Are you trying to power a motherboard designed for 12V or 19V? Or a pico psu that plugs into the atx 24?

These two work together:

http://www.mini-box.com/12v-16A-AC-DC-Power-Adapter 4 pin not round center post like a laptop

Trying a regular 19V laptop charger in it will destroy it

Gigabyte Intel H81 Mini ITX or a Gigabyte LGA 1150 H97. The case I am ordering has a DC controller that has a 24 atx plug coming out of it.

One thing I am confused about. Is that picoPSU-160-XT, 160w output, 12v input DC-DC Power Supply a complete PSU? If so, how does it plug into a wall? Sorry, you answered my question when you said those two work together! Do you think they would work for my board?

Good that you mentioned not trying a laptop charger as that was one of the things I thought might work lol.

I had a look at that link you posted mini-box.com and they have no phone number available at all anywhere on there website. I have had pretty bad experience when companies hide behind email only unfortunately.

It was an example, may have to find an itx htpc forum and see what and where they get their pieces. If you bought both those parts it looks like you use the power brick connector and unplug the 4 pin connector then plug it into the pico psu 4 pin connector, so you have the jack on the pc and can insert the power cable. If the case has the connector and 24 pin as a pico powersupply then you just need to add the matching 12v brick
