anyone else got any experience on this issue? 

recently got a couple of new 7600's, both chassis reading 1019W on both
PSU's. im on my 3rd rma now, each time just turns up more PSU's that report
wrong wattage. TAC are telling me they have no idea which PSU's at the depot
are faulty and which are not, so they are just sending me PSU's RMA after
RMA until we end up with all working ones.. somewhat peculiar way of
approaching the issue..

1    PWR-1900-AC/6      1019.34 24.27  OK     OK     on
2    PWR-1900-AC/6      1869.42 44.51  OK     OK     on

meh
