KHACHIMO FLEX NAS LOLI Small 1U 400W ATX Power Supply ENP-7140B

Compact 1U ATX PSU for dense builds

This 400 W unit fits a 1U chassis and carries 80 PLUS Gold certification for efficient power delivery. It targets NAS appliances and small-form-factor servers that need reliable output in a slim profile. Modern Standby support allows rapid wake-from-sleep behaviour. The resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight.

400 W continuous capacity and headroom

The supply delivers its full 400 W rating across the combined rails for typical NAS workloads and embedded boards. Peak demands beyond that level will trip protection, so multi-GPU arrays or heavily overclocked CPUs are outside its design envelope. Builders needing more than 400 W should select a higher-rated unit.

Thermals noise and power draw in normal use

Zero RPM mode stops the fan completely at low and medium loads, yielding near-silent operation during idle or light file-serving tasks. Gold-level efficiency reduces waste heat, keeping internal temperatures lower in confined 1U enclosures. The resonant LLC design also suppresses coil whine for quieter overall acoustics.
