After printing for over a year, this is the first time I've noticed this. For some reason my bed can only achieve 111C during the print.
It seems that maybe this is because the print head and motors are drawing too my power from the PSU, but can anyone comment?

I assume you don't have the fan running?
The load does not increase over time, so I think either the PSU maybe faulty or you have a bad connection that is heating up. Or possibly if it can only just make it the movement of the bed is enough to cool it, although it should be able to hold 130C with the bed moving in a warm room.
Measure the 12V at the Melzi and see if it drops over time.
