That is triton-I, as in Triton-II the TSC has been compined with the TPD
chips, so for Triton-II you would have a SB82371SB and a FW82439HX.

These tend to stay the same on most vendors Triton-II board, ASUS seems
to have gone back to the SMC669, but that can change as the parts are
pretty much interchangable except for bios programming.
