Compact 1U ATX power supply unit with gold finish

KHACHIMO

KHACHIMO 1U 250W ATX Power Supply Gold Zero RPM

SKU CH-0NSE-5TQAE

A compact 1U ATX unit delivering 250 W with 80 PLUS Gold efficiency, Zero RPM fan silence and Modern Standby support

  • TypeATX
  • Modern Standby support for near-instant wake times
  • 80 PLUS Gold certified for high efficiency and lower heat
  • Zero RPM fan mode keeps the unit silent under light loads
  • Resonant LLC with DC-to-DC conversion delivers clean, stable power
  • Compact 1U form factor fits space-constrained server and workstation builds

1U ATX Power Supply for Compact Builds

This 250W ATX unit fits the 1U form factor used in rackmount and slimline chassis. It targets system integrators and enthusiasts assembling space-constrained PCs that still require standard ATX power delivery. The gold-rated efficiency and modern standby support suit always-on or frequently sleeping workloads.

Sustained Load Behaviour and Acoustics

The resonant LLC topology with DC-to-DC conversion maintains clean voltage regulation across the full operating range, reducing coil whine under continuous demand. At low and medium loads the zero RPM fan mode stops the fan completely, so extended idle or background tasks run silently. The 80 PLUS Gold certification ensures high efficiency is preserved during prolonged operation, limiting waste heat inside tight enclosures.

Upgrade Path and When It Makes Sense

The supply replaces older, lower-efficiency 1U units that lack modern standby compatibility or semi-passive cooling. The jump is worthwhile when a build demands faster wake-from-sleep response, quieter acoustics at typical desktop loads, or the tighter voltage regulation that DC-to-DC conversion provides. It is not suited for configurations requiring more than 250W of combined output.

Highlights

  • Modern Standby support for near-instant wake times
  • 80 PLUS Gold certified for high efficiency and lower heat
  • Zero RPM fan mode keeps the unit silent under light loads
  • Resonant LLC with DC-to-DC conversion delivers clean, stable power
  • Compact 1U form factor fits space-constrained server and workstation builds

Questions about this item

How quiet is the 250W unit during all-day operation with Zero RPM mode?

At low and medium loads the fan stops completely, and the Resonant LLC topology with DC-to-DC conversion reduces coil whine for near-silent running.

What connectors must my system already provide for this 1U ATX supply?

It uses a standard ATX form factor, so the motherboard needs a 24-pin main power socket and a 4-pin or 8-pin CPU power socket.

Will the 80 PLUS Gold efficiency benefit an older build I keep?

Yes, the Gold-rated efficiency lowers power draw and heat at every load level, helping older components run cooler.
