KHACHIMO SS-500L1U 1U 500W 80plus Gold power supply

SKU CH-8EJY-A070T

An 80 PLUS Gold certified 1U ATX power supply delivering 500 W with Modern Standby support, Zero RPM fan mode and resonant LLC DC-to-DC topology for silent, efficient operation

  • TypeATX
  • Faster wake-from-sleep and better low-load efficiency with Modern Standby support
  • High efficiency operation cuts power draw, noise and heat with 80 PLUS Gold certification
  • Near-silent running at low and medium loads thanks to Zero RPM fan mode
  • Clean, consistent power delivery and reduced coil whine via resonant LLC topology with DC-to-DC conversion
  • 500W ATX output in a compact 1U form factor for space-constrained builds

1U 500W ATX Gold Power Supply

The KHACHIMO SS-500L1U is a 1U form-factor ATX power supply rated at 500 W. It carries 80 PLUS Gold certification and includes Modern Standby compatibility for rapid wake-from-sleep and improved low-load efficiency. The unit uses a resonant LLC topology with DC-to-DC conversion to deliver clean, consistent power while reducing coil whine.

Suits compact servers

This supply fits 1U rackmount chassis and other space-constrained builds that require ATX power in a slim profile. Zero RPM fan mode keeps acoustics near silent at low and medium loads. Builders who need a different form factor, higher wattage, or modular cabling should look at alternative units.

80 PLUS Gold certified 500W output

The single specification that decides fit is the 500 W continuous rating combined with 80 PLUS Gold efficiency. If your system power budget exceeds this limit, or if the chassis cannot accept a 1U ATX unit, this model will not meet the requirement.

Questions about this item

What 80 PLUS rating does this 500 W unit carry?

It is 80 PLUS Gold certified, meaning it meets the Gold efficiency thresholds for lower power draw, less heat and quieter running.

How does the 500 W rating translate to real-world use?

The unit can deliver up to 500 W of continuous power to your components while maintaining Gold-level efficiency across typical loads.

What ATX standard does this supply follow and what does that limit?

It follows the ATX form factor, so it fits standard ATX cases and its 500 W output caps the total system power it can support.
