DQ77KB - how to power without external PSU

Community Manager

Hi all.

Does anyone know to power the DQ77KB board with the two-pin PCB connector (instead of an external PSU)? I cant seem to find the right type of cable.

The plan is to put this mobo in a Chenbro ES34069 chassis that actually have its own external PSU already, but has "normal" ATX style 20 pin cabling for powering the motherboard.

I would like to reuse this chassis and PSU with the DQ77KB, but need to know how to power it.

Any help is appreciated,

There is a 3rd-party vendor for an internal PSU for DQ77KB and other thin-miniITX boards.

Vendor: HuntKey

Model no.: HKF1501-3A

Desc: 150W internal PSU (19V/7.9A)

The 2-pin internal Molex connector still requires 19V DC, same as the external DC jack. Pin 1 (near the lock) is 19V DC and the other is ground.

As far as connectors go, half of a standard 2x2 CPU cable connector would work as long as it provides the 19V DC. (FYI, 2x2 CPU output from a standard ATX PSU is only 12V DC).

This website has a module that convert input from a battery of one voltage to a battery of another voltage. So you could use some kind of other batteries or build your own LION Battery Pack from say a rechargable batter for an electric bicycle or something like that.
