Power Supply

3.1

External AC Adapter

An external AC adapter is envisioned for operation of a Thin Mini-ITX based AIO
system. The output of the adapter is dependent on the overall power of the system as
determined from the desired feature set. The external AC adapter output will vary
from approximately 100W to an Atom based system to over 200W for a 65W feature
rich system design.
AIO systems utilizing 35W, 45W and 65W Sandy Bridge/Ivy Bridge processors would
likely use AC adapters with power rating ranging from 120W to 150W, depending on
system-level power budget. Cedar Trail based systems would likely use 90W to 120W
AC adapters, depending on system-level power budget. AC adapters for SFF chassis
that do not use internal flat panel displays may be 20-30W lower in power output.
3.2 External Power Connector for Socketed CPU
Based Systems
The below image shows reference dimensions for the recommended external 19V DC
power connector type to be used for socketed CPU based, as well as Atom CPU based,
Thin Mini-ITX systems developed to this Design Guide. Aligning on this connector
type helps simplify component sourcing and selection for integrators.
PS_ID (Power Supply ID) is not supported as a feature on the center pin of the
motherboard header and power adapter connector. If the center pin of the
motherboard header has a trace routed to it, then ESD (electrostatic discharge)
protection must be included on it.
Recommended power jack type: Singatron 2DC1003-000211F (or equivalent)*
