200W ATX power supply for A1311 AIO

This 200W ATX unit is built specifically for the KHACHIMO 21.5" AIO A1311 all-in-one desktop. It replaces the original ADP-200DF B power board when that component fails or when a spare is kept on hand for service work. The part number OT8043 identifies the exact revision required by the chassis.

Standard ATX fit with proprietary connector

Installation follows normal ATX mounting points, but the output harness uses the proprietary connector keyed to the A1311 motherboard. The most common issue is forcing the connector the wrong way round, which bends pins and prevents the system from posting. Verify the key orientation before applying pressure.

200 watt continuous capacity with Gold efficiency

The 200 watt rating covers the AIO’s CPU, integrated graphics, memory and storage under full load while maintaining 80 PLUS Gold efficiency. Headroom is tight; adding a discrete graphics card or multiple high-power drives will exceed the unit’s capability and trigger protection shutdown.
