Compact 1U 350 W PSU for rack builds

The KHACHIMO FLXA5351A is a 1U form-factor ATX power supply rated at 350 W and built for space-constrained servers or workstations. It targets system integrators who need reliable power in a single rack unit without sacrificing efficiency certifications.

80 PLUS Gold efficiency under continuous load

The unit holds 80 PLUS Gold certification, meaning it maintains high efficiency across sustained workloads rather than only at peak bursts. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power while reducing coil whine, and Modern Standby support enables deeper, more energy-efficient sleep states during idle periods.

Verify 1U clearance and ATX connector fit

Confirm your chassis accommodates a 1U height power supply and that the ATX connector layout matches your motherboard. The Zero RPM fan mode stops the fan at low and medium loads for near-silent operation, but airflow must still be sufficient for the enclosure when the fan spins up under heavier demand.

Perguntas sobre este artigo

How loud is the 350W unit when it runs all day in a 1U chassis?

Zero RPM Fan Mode stops the fan completely at low and medium loads for near-silent operation, while 80 PLUS Gold efficiency keeps heat and noise lower at higher loads.

What cables or connectors must I already have to install this ATX power supply?

Standard ATX motherboard and peripheral cables are required; the unit uses the ATX form factor so existing ATX-compatible cables will fit.

Will the resonant LLC topology with DC-to-DC conversion cause issues with older components I keep?

The topology delivers clean, consistent power and reduces coil whine, making it compatible with older hardware while supporting modern sleep states.
