12V direct from Alienware 17 R2 mobo

[gbellman]

Hi all, I'm wondering how can I get 12V direct from AW17 R2 mobo? My system was built from AW17 R2 mobo, no battery and no lcd, I'm using external monitor and direct dc adapter.

System specs:
Cpu: i7-4710
Gpu: gtx 980m 4gb
Ram: Corsair Vengeance 16gb ddr3
Dc adapter: Flextronics 19.2V 12.3A 240w

Some suggest that I tap 12V from battery port, but some said mobo won't charge when there's no battery detected. Some also suggest that I get the 12V from display port (not the vga/hdmi), but I'm not sure. Wish that any expert can help me out, thanks.

With something like that, you could tap off of the 19.2V adapter.

I recently built a similar power supply board from a kit.

They also have these type:
