KHACHIMO YM-5411B 405W Redundant Server Module

This KHACHIMO YM-5411B is a 405W redundant power supply module designed for 3Y server systems. It uses an ATX form factor and functions as a hot-swappable unit within a CP-1121R2 redundant chassis.

Verify Chassis Compatibility Before Ordering

Confirm that your server chassis accepts the CP-1121R2 redundant form factor and that the 405W output matches the original specification. This unit is not a standalone ATX power supply for standard desktop builds. Buyers needing a single non-redundant unit or a different wattage should look elsewhere.

How do I choose between the 405W module and other capacities for the CP-1121R2?

Select the 405W YM-5411B when your 3Y server configuration matches this wattage and the CP-1121R2 redundant slot; other capacities are for different server power budgets.
