VICOR MegaPAC MP3-77542 ATX unit

This KHACHIMO power supply is built to the ATX form factor and carries the VICOR MegaPAC MP3-77542 designation. It is intended for system builders and technicians who need a multiple-output unit that has been tested and confirmed working. The supply targets desktop and workstation configurations requiring standard ATX mounting and power distribution.

Multiple-output capacity and headroom

The unit delivers several regulated rails from a single ATX frame, providing the voltage combinations typical of MegaPAC designs. It handles normal desktop loads and peripheral draws without issue. Headroom diminishes when all rails are loaded near their rated limits simultaneously, so configurations with many high-draw drives or expansion cards may exceed the combined output capability.
