Probably an OEM unit inside an HP or something. I think Delta have a couple 180W units with gold efficiency, but I don't know anything about them.
You think a 3200G pulls 130W idle??? That's the only component in the system currently with any substantial power draw ... And it's not 130W!!

Check the power consumption numbers in there.... And that's the 3400G, so SMT + stronger GPU vs what the OP has.
Obviously it'll depend on system specifics, but I think your numbers are way off. Probably right on the money with ~130W under full load.
As configured, today? Pre-GPU add? Not. A. Chance.
I'm assuming it's a prebuilt and if that's the case, the "180W" will be fine, as configured at the moment, for the duration of the systems warranty.
