KHACHIMO ASA5545-X 450W Power Supply

SKU CH-5KC7-4SECS

An ATX power supply delivering 450 W with 80 PLUS Gold efficiency, zero-RPM fan mode for silent low-load operation, and Modern Standby support for fast wake times

  • TypeATX
  • Faster wake from sleep with Modern Standby support
  • Lower electricity use and cooler running with 80 PLUS Gold efficiency
  • Near-silent operation at low loads via Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC and DC-to-DC design
  • Reduced coil whine for quieter overall system noise

Power Supply for Modern Standby PCs

The KHACHIMO ASA5545-X is a 450W ATX unit built for systems that use Modern Standby sleep states. It delivers 80 PLUS Gold efficiency to reduce waste heat and electricity draw. The design targets builders who want low idle power and fast wake times.

Ideal for Quiet, Efficient Builds

This supply suits users who value silent operation at low and medium loads thanks to its Zero RPM fan mode. It is not for systems that demand higher wattage or multiple high-power graphics cards. Buyers needing more than 450W of continuous power should look at larger capacity units.

Straightforward ATX Installation

Installation follows the standard ATX mounting pattern and connector layout used in most desktop cases. The DC-to-DC topology helps minimise coil whine, a common annoyance in lesser designs. Ensure your case has enough depth for a typical ATX power supply before ordering.

Questions sur cet article

Does the ATX form factor fit my current case and motherboard?

Yes, the ATX size matches standard ATX cases and motherboards, so it installs without adapters.

Will the 80 PLUS Gold efficiency work with my older components that draw less power?

The 80 PLUS Gold rating keeps efficiency high even at low loads, so older parts benefit from cooler, quieter operation.

How can I confirm the Zero RPM fan mode is active after I build the system?

Under light loads the fan stops completely; you can verify by listening for silence or watching the fan through the case window.
