2U ATX Power Supply for Compact Builds

The KHACHIMO LL2U500APFC is a 2U form-factor ATX power supply rated at 500 W. It fits servers and workstations where rack height is limited and a standard PSU cannot be installed. The unit targets system integrators who need reliable power in shallow chassis.

Sustained Load Behaviour with Gold Efficiency

80 PLUS Gold certification means the unit maintains high efficiency across typical operating loads, reducing waste heat during continuous operation. Resonant LLC topology with DC-to-DC conversion delivers stable voltage rails under sustained demand, supporting modern sleep states without rail instability.

Thermals Noise and Power Draw in Normal Use

Zero RPM fan mode stops the fan completely at low and medium loads, providing near-silent operation for idle or light workloads. High efficiency lowers overall power draw and case temperatures, while the topology reduces coil whine for quieter acoustic output.

Questions sur cet article

How loud and hot does the LL2U500APFC get during all-day use?

Its 80 PLUS Gold efficiency keeps waste heat low, and the Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running.

What must my system already have for this 500 W ATX unit to work?

A standard ATX motherboard and case that accept a 2U form-factor PSU with a 24-pin main connector and 4/8-pin CPU power lead.

Will this supply run reliably with older components I keep?

Resonant LLC topology with DC-to-DC conversion delivers clean, stable rails that reduce coil whine and support modern sleep states on legacy hardware.
