SKU CH-7JNH-4S2HY

ATX power supply delivering 300 W with 3.3 V at 60 A, 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for silent, low-load operation

  • TypeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low load
  • Resonant LLC with DC-to-DC gives clean power and less coil whine
  • 3 V rail delivers 60 A for stable component supply

300 W ATX power supply

This 300 W ATX unit delivers 60 A on the 3.3 V rail and carries 80 PLUS Gold certification. It uses resonant LLC topology with DC-to-DC conversion for stable voltage regulation and reduced coil whine. The design targets modern desktop systems that require efficient, low-noise power delivery.

Suited for modern standby builds.

Builders who want Modern Standby support, fast wake-from-sleep, and a Zero RPM fan mode at low loads will benefit from this platform. Systems that demand more than 300 W total output or greater current on rails other than 3.3 V should look at a higher-capacity design.

60 A on the 3.3 V rail

The 3.3 V rail is rated at 60 A, which determines how much current is available for components that draw primarily from this voltage. Verify that your motherboard and peripherals stay within this limit before selecting this unit.

Questions about this item

Does the KHACHIMO ATX 300W unit ship with all required ATX cables attached, or must I purchase any cables separately?

The power supply has fixed ATX cables installed, so no separate cable purchase is needed for a standard build.

How do I decide between the 300W model and a higher-wattage unit for my system?

Choose this 300W model if your total component draw stays below 300 watts; select a higher-wattage unit only if your build needs more power headroom.

What does the 80 PLUS Gold rating mean for daily power draw and heat inside my case?

The 80 PLUS Gold rating means the unit runs at high efficiency across typical loads, lowering electricity use and reducing waste heat in the case.
