The motherboard power requirements are heavily dependent on system configuration and the
software being used. The table below can be used as a guide to the likely power supply
requirements. They are measured using a 400MHz Intel Celeron Processor and 2 memory
modules running stress test software designed to yield worst case results. They should not,
however, be regarded as maximum values.

Note that these figures do not cover cards plugged into the slots.
When operating this motherboard with a power supply that does not provide a +5V
standby output, the PL8 jumpers (installation guide reference 2) must be fitted.
Advisory
Mitsubishi has found that some power supplies generate damaging voltages on their main
outputs when their +5V standby output is over-loaded.
The PCB is a four-layer design measuring W7.8" x L12.0". It is ATX 2.01 compliant. The inner
power planes are arranged so that the ground plane is nearest the top component layer.
The PCB has a UL flammability rating of 94V-0.
