  • TypeATX
  • Faster wake-from-sleep with Modern Standby support

  • Fan stops completely at low load for silent running
  • Resonant LLC plus DC-to-DC topology delivers clean power
  • 480 W ATX output for reliable system operation

Compact 2U 480W ATX Power Supply

The KHACHIMO NF5220 is a 2U form-factor ATX power supply rated at 480W, designed for rackmount chassis or space-constrained builds that require a standard ATX electrical interface in a low-profile enclosure. It suits system integrators and IT professionals deploying servers or workstations where vertical clearance is limited but reliable power delivery remains essential.

80 PLUS Gold Efficiency Rating

The unit carries 80 PLUS Gold certification, meaning it meets strict efficiency targets at typical loads, reducing waste heat and lowering operating costs over time. This single specification is the primary indicator of whether the power supply matches a build’s thermal and energy-efficiency requirements.

Straightforward ATX Installation

Installation follows standard ATX mounting and cabling procedures, so experienced builders can fit it without special tools or adapters. The resonant LLC topology with DC-to-DC conversion minimises coil whine, while the zero-RPM fan mode keeps the unit silent at low loads; however, the 2U height may not fit tower cases designed for full-height PSUs, and cable lengths are optimised for compact layouts rather than full-size enclosures.

  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops completely at low load for silent running
  • Resonant LLC plus DC-to-DC topology delivers clean power

Questions sur cet article

What does the 480 W rating mean for a typical desktop build?

It delivers up to 480 W of continuous power, enough for mainstream CPUs and mid-range graphics cards while leaving headroom for drives and peripherals.

How does the 80 PLUS Gold certification affect daily use?

It guarantees at least 80 % efficiency at typical loads, reducing electricity draw, heat output and fan noise compared with lower-rated units.

Will this 2U ATX unit fit in a standard tower case?

The 2U form factor is designed for rack or slim enclosures; verify your case supports 2U-height power supplies before installing.
