I have very recently picked up a G68ADV which was advertised as having an LPSU fitted; as there were problems with the front panel switches I took off the top panel to investigate.
What I found was an SMPS, but not the original one as expected :-

but rather the one shown in the photo of the G61R internals.

Is this a legitimate replacement, or should I find a more suitable product?
