  • TypeATX
  • 80 PLUS Gold certified for lower power draw and cooler running
  • Zero RPM fan mode keeps the unit silent at low and medium loads
  • Modern Standby compatible for faster wake-from-sleep and better idle efficiency
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 12 V rail rated at 36 A for stable output under load

Modern Standby ATX supply

The KHACHIMO 450 W ATX unit delivers 12 V at 36 A and carries 80 PLUS Gold certification. It targets builders who want efficient, quiet power for systems that use Modern Standby sleep states.

12 V 36 A single-rail output

The 12 V rail provides the full 450 W capacity, so the supply suits configurations where the graphics card and CPU draw most of their power from that rail. Systems needing multiple 12 V rails or higher total wattage should look elsewhere.

Zero RPM fan and LLC topology

A resonant LLC design with DC-to-DC conversion keeps output clean and reduces coil whine. The fan stops completely at low and medium loads, enabling near-silent operation while the PC idles or wakes instantly from Modern Standby.

Questions about this item

What does the 450 W rating mean for a typical desktop build?

The unit can deliver up to 450 W of continuous power across all rails, enough for mid-range CPUs and GPUs in a standard ATX case.

How does the ATX form factor limit installation options?

It fits any standard ATX chassis and uses the 24-pin motherboard connector plus the usual CPU and PCIe power leads.

What physical clearance does the 12 V 36 A rail design require inside the case?

The PSU measures a standard ATX depth, so allow at least that length behind the motherboard tray plus cable routing space.
