Compact Server Power

The KHACHIMO LL1U800APFC is a 1U form-factor ATX power supply rated at 800W. It targets system integrators building rackmount servers or dense workstations where vertical space is limited and reliable, efficient power delivery is required.

Build Integration

The 1U height allows installation in standard rack chassis without consuming extra rack units, freeing space for additional compute or storage modules. Its ATX connector set supports typical server motherboards, while the LLC resonant topology with DC-to-DC conversion delivers stable voltage rails for continuous operation.

Efficiency & Acoustics

80 PLUS Gold certification confirms high efficiency across load ranges, reducing waste heat and operating cost. Modern Standby compatibility enables rapid wake-from-sleep transitions, and the Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running in noise-sensitive environments.

Questions about this item

Will the 800 W output hold steady during continuous full-load operation?

The 80 PLUS Gold certification confirms high efficiency at typical loads, which reduces waste heat and helps the unit sustain its rated 800 W output without throttling.

How loud and hot does the power supply get when running 24/7?

Zero RPM Fan Mode stops the fan completely at low and medium loads for silent running, while the resonant LLC topology with DC-to-DC conversion minimises coil whine and keeps temperatures lower under sustained use.

What motherboard power connectors must my system already provide for this unit to work?

As an ATX-type supply it uses the standard 24-pin main connector and 4- or 8-pin CPU power leads; Modern Standby compatibility also requires a motherboard that supports the appropriate low-power sleep states.
