PSU upgrade - 1 unidentified connection on mobo, help!

[slickblade]

I was trying to upgrade my pre built sony vaio - PCV-RS620G

and encountered a problem (besides thinking the psu is going to be too big).

Their is a 3 pin connection running from the psu to the mobo that i cant figure out, as the new psu does not have these 3 cords.... the cords are black, blue, and grey and connect just next to the 20 pin connection.

The mobo is - P4S0-VL
Current psu - Sony P/N 1-468-826-11


ive tried finding some info on these to determine what the specs are but have been unsuccesful.

Anyone know what the connection is, and any recommendations for a psu to fit this model?
