560W 1U Server Power Supply

The KHACHIMO PWS-563-1H20 delivers 560W of power in a 1U form factor designed for server chassis. It uses an ATX type connection layout for compatible backplanes. This unit suits administrators building or repairing rackmount systems where space is limited. Buyers needing higher wattage or redundant modules for critical uptime should look elsewhere.

Fits standard 1U server bays

The supply slides into a 1U bay and connects via the ATX interface to the server backplane or motherboard. Its compact height frees vertical space for additional compute or storage density in the rack. Installation requires a chassis with matching 1U power supply mounting rails and the correct power distribution board. Systems requiring hot-swap redundancy need a different chassis architecture.

Tested for reliable operation

Each unit is test working before dispatch to verify basic electrical function under load. The 1U form factor typically uses high-speed fans to move air through the restricted volume, so audible noise is present in normal server rooms. Power draw at the wall will reflect the connected components up to the 560W rated capacity. No efficiency certification or specific thermal data is provided by the supplier.

Questions about this item

What is the maximum continuous output the PWS-563-1H20 can deliver?

The unit is rated for 560 W of continuous power, which is the limit that will be reached first during sustained heavy loads.

How does the 1U server supply behave thermally and acoustically when running 24/7?

The 1U chassis uses a compact internal fan to exhaust heat toward the rear; expect noticeable airflow noise and warm exhaust air during all-day operation.

Which power connectors must my system already provide for this ATX supply to function?

It requires a standard ATX 24-pin motherboard connector plus the matching CPU and peripheral leads that your chassis and board already supply.
