KHACHIMO

KHACHIMO 450W power supply for ORION-450AX

SKU CH-WKJC-GS8N8

An ATX unit delivering 450 watts with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and LLC resonant topology with DC-to-DC conversion

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops completely at low load for silent running
  • LLC resonant topology with DC-to-DC delivers clean, stable power
  • 450 W ATX unit built for the ORION-450AX

Designed for ORION-450AX systems

This 450W ATX power supply is built specifically for the ORION-450AX platform. It delivers 80 PLUS Gold efficiency and supports Modern Standby for rapid wake times. The unit suits builders replacing an original supply or assembling a matching chassis. It is not for buyers who need a higher wattage rating or a standard retail form factor for other cases.

Resonant LLC topology with DC-to-DC conversion

The resonant LLC design combined with DC-to-DC conversion maintains clean, consistent voltage rails during sustained workloads. This topology reduces coil whine and enables deeper, more efficient sleep states. The 80 PLUS Gold rating ensures lower power draw and cooler operation over long sessions. Zero RPM fan mode keeps the unit silent at low and medium loads.

Direct-fit ATX installation

Installation follows the standard ATX mounting pattern used by the ORION-450AX chassis, so no adapter brackets are required. Cable lengths match the original routing channels, avoiding clutter or tension. The main risk is confusing this unit with generic 450W models that lack the specific connector keying or Modern Standby handshake. Verify the ORION-450AX label before fitting.

Questions about this item

How quiet is the KHACHIMO 450W during all-day use?

The Zero RPM fan mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter operation.

What connectors must my system already have to use this unit?

It uses a standard ATX form factor, so your case and motherboard need matching ATX mounting points and a 24-pin main power socket plus the usual CPU and PCIe leads.

Will the KHACHIMO 450W work with older components I plan to keep?

The ATX design and DC-to-DC conversion deliver clean, consistent power that supports modern sleep states while remaining compatible with legacy hardware power requirements.
