1U ATX Power Supply for Rack Builds

The KHACHIMO ACE-816AP is a 1U form-factor ATX power supply designed for rackmount chassis and compact servers. It carries 80 PLUS Gold certification for high efficiency and lower running costs. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. A resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine.

Suited for Dense Servers and Quiet Workstations

This unit fits system integrators deploying 1U rackmount servers or space-constrained workstations where silent operation matters. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Builders needing higher wattage for multi-GPU configurations or full-tower ATX cases with standard PSU bays should consider larger form-factor units instead.

816 Watt Output Defines the Power Budget

The 816 W rating sets the total power available for all components in the chassis. Pair this figure with the combined draw of your CPU, memory, storage and add-in cards to confirm the supply meets the system load. No other specification overrides this single capacity limit when selecting the right part.
