1200W Redundant Server Power Supply

The KHACHIMO PWS-1K21P-1R delivers 1200W of power in a redundant ATX form factor designed for server environments. It includes hot-swap capability so a failed unit can be replaced without downtime. This new unit has been tested working and is built for continuous operation in rackmount systems.

Practical Limits of Redundant ATX Power

Redundant supplies share the load, so total capacity drops to a single unit's rating if one module fails. The ATX footprint restricts use to chassis with matching bays and backplane connectors. Buyers needing higher wattage per module or non-redundant desktop ATX units should consider other form factors.

Questions about this item

Should I pick the 21-slot or the 1200-slot version?

The model uses a single 21-pin main connector and delivers 1200 W total output; there are no alternate slot counts or wattage tiers to choose between.

What does the 1200 W rating mean once the unit is installed in a server?

It means the redundant supply can continuously provide up to 1200 watts to the system while sharing the load with a second identical unit for failover protection.
