I called Mini-box for some clarification. The agent told me that as the manual states, their barrel plug is rated for up to 16A. I also checked the cable going from the barrel plug to the DC-DC PSU and it is 16-guage, which can support up to 22A for chassis wiring. Since this family member is not planning on loading it beyond just a Ryzen 5 2400G at stock settings, I feel this far more than sufficient for HTPC and light gaming duty.Nice find. Like @aquelito noted, the jack also needs to be rated for the current. I would contact Mini-box about the current rating of their jack or keep a very close eye on temperatures.
