3.5 MECHANICAL SPECIFICATIONS
The mechanical drawing of the subject power supply, which indicate the form factor, location 
of the mounting holes, location, the length of the connectors, and other physical specifications
of the subject power supply. Please refer to the attachment drawing.

( 1 ) +3.3V & +5V total output not exceed 152W.
( 2 ) +3.3V & +5V & +12V1 & +12V2 total output not exceed 380W.
( 3 ) Maximum combined current for the 12V outputs shall be 29A.
( 4 ) +5VSB Peak current loading is 2.5A , shall be supported for a minimum of 500m second.
Voltages and ripple are measured at the load side of mating connectors with a 0.1 uF monolithic 
ceramic capacitor paralleled by a 10 uF electrolytic capacitor across the measuring terminals.
