I purchased an Intel Boxed Motherboard DN2800MT. I am very excited to get it going. However, I don't have the correct power solution.
I found in the Technical Product Specification (TPS) there are two options: use External AC Adapter at the DC input Jack or use a 1x2 connector on the PCB.
For the 1x2 connector, the TPS gives the manufacturing part numbers for the mating connectors. I can try to order them. I think I found them on mouser. Then I will wire something up. Probably not too elegant.
For the circular DC input. The TPS says it is a 5.5mm outer diameter and a 2.5 inner diameter. I looked through my collection of AC adapters from old laptops. My old Gateway seemed to have the correct dimensions. Here is a link to an online copy of it.
The TPS says it is 5.5mm and 2.5mm, BUT it does not fit. It looks like it would slip in but the post of the PCB connector is too big around. Are the dimensions in the TPS correct? I am bit nervous to order another adapter with these dimensions to find out it doesn't fit either. Is there a list of compatible AC adapters? Maybe with a link to where they can be purchased? (Or at least a link to the manufacturers website so I could ask them where to buy one).
OK my question is sorta answered. My favorite computer shop here in Hillsboro Oregon didn't have a compatible supply (AC adpater with the correct connector).
I found two links for the DN2800MT with companies advertising a compatible Power Supply:
Since I am on the west coast and logicsupply looks like it is based on the east coast, I selected the mini-box solution.
I only need to power the board, 1 SO-DIMM and the hard disk so I bought the smaller one, their 60W (12V at 5A). It came. I tried it. Only the standby LED came on.
The local shop said that it is probably under powered. So decided to buy a bigger 12V supply. The local Frys (Wilsonville) had this:

I decided something else must be wrong and maybe the whole 12V thing isn't working. Frys had an Antec mini-skeleton-90 chassis that comes with a 19V at 5A supply. http://www.antec.com/product.php?id=2102&fid=23 Tried that supply, still not booting. I hooked all the skeleton controls (power switch, reset button).
Hmmm, anyone else have better luck? Any suggestions?
All of the power supplies mentioned above: The small 12V one, the slightly larger 12V one and the Skeleton 19V one can power the DN2800MT. The issue is the DVD drive was causing the system to hang. This is the offending USB DVD drive: http://www.newegg.com/Product/Product.aspx?Item=N82E16827140049
Any time this drive is attached when BIOS runs (like right after reset), the board will hang before keyboard or video.
