PSU for GA-81gvt aka G-Max TA4

[SpeedEng66]

ok I just got my hands on a mini-itx like board but no psu

it has a power din (for power using a external like a laptop psu)
what the plug looks like)


now im itching to cut one of my spare laptop plugs (about the same spec)
but here's the problem
which one is 12, 5, 3.3 and which one is ground?

I tried searching to the end on google and came up empty
maybe there's some pro's out there that migh know

Have you tried plugging it in to a/c power and testing with a DMM?
