Jeantech 400w PSU connector

[BigAl]

I am installing a Jeantech 400w PSU using an AS8-V motherboard.
All the connectors on the PSU are self explanatory except one. It is a white three bank connector with  two wires on the outer of  the connector, a black and orange and an orange.  It is a type that would fit onto one of four connectors on the motherboard Sysfan1, Auxfan1 Auxfan2 and the NBfan1.  I am assuming that these are 'output' pins on the mobo so where would this power connector be used?
