Yeah it's a generic header, pretty sure I have one exactly the same on an old PSU, remember the shorter than expected pins.

I know the chip can do 1.8, tho it's generally only used for 3.3/5v, on similar cables. Nice having free connectors tho, if the headers pins are long enough, pretty sure they should be.
