KHACHIMO TURBO-COOL EDGE -5V 1U 300W power supply

SKU CH-CPGD-SJKDA

A 300W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • Product typeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold efficiency reduces power draw and heat
  • Zero RPM fan mode keeps the unit silent at low loads
  • Resonant LLC with DC-to-DC conversion delivers stable, clean power
  • Compact 1U 300W ATX design fits space-constrained builds

Compact 1U server power supply

This 300 watt ATX unit fits standard 1U rack chassis and supports Modern Standby for rapid wake-from-sleep. The 80 PLUS Gold rating ensures high efficiency across typical server loads, reducing heat and operating cost. Zero RPM fan mode keeps acoustics near silent at low and medium demand. Resonant LLC topology with DC-to-DC conversion delivers clean power and minimises coil whine.

Straightforward 1U installation

The unit slides into any standard 1U rack bay and uses the regular ATX connector set, so no adapter cables are required. Ensure the chassis airflow path matches the supply’s front-to-rear design; restricted intake is the most common cause of thermal throttling. Verify that the total system draw stays within the 300 watt rating before powering on. Cable routing in dense 1U builds can be tight, so plan connector placement early.

300 watt capacity for dense builds

The supply comfortably handles single-socket servers, storage nodes, or network appliances drawing up to 300 watts continuous. Headroom shrinks when multiple high-wattage CPUs, GPUs, or large drive arrays are added, so calculate peak load carefully. At loads above roughly 80 percent the fan engages to maintain safe temperatures. Systems requiring sustained power beyond this level need a higher-capacity unit.

Questions about this item

How can I verify the KHACHIMO TURBO-COOL EDGE 300W unit is operating correctly after installation?

The 80 PLUS Gold certification confirms high efficiency; check that the fan stays off under light load thanks to Zero RPM mode and that the system wakes instantly from sleep via Modern Standby support.

What cables and accessories are included with the KHACHIMO TURBO-COOL EDGE 300W, and what must I source separately?

The ATX power supply ships with its fixed cable set; any specialised GPU or drive cables not already attached will need to be purchased separately.

Which capacity of the KHACHIMO TURBO-COOL EDGE series should I choose for my build?

This model delivers 300 watts; select it when your total system draw stays comfortably below that figure.
