KHACHIMO 460W ATX power supply H460EBM-00 80 PLUS Gold

SKU CH-KA2N-6K5Q7

An ATX power supply delivering 460 W with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for clean, quiet power

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops at low load for silent running
  • LLC resonant topology with DC-to-DC for stable voltage
  • Clean power delivery reduces coil whine and noise

ATX 460W Gold Efficiency

The KHACHIMO H460EBM-00 is an ATX power supply rated at 460 watts with 80 PLUS Gold certification. It targets builders who need reliable, efficient power for mainstream desktop systems. The unit supports Modern Standby for rapid wake-from-sleep transitions. It fits standard ATX mounting points and wiring layouts.

Sustained Load Behaviour

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power under continuous demand. Zero RPM fan mode keeps the cooling fan off at low and medium loads for near-silent operation. The fan engages only when thermal conditions require active airflow. Efficiency remains high across the load range, reducing waste heat and acoustic output during extended sessions.

ATX Interface Limits

The ATX form factor defines the physical and electrical boundaries for this supply. Maximum output is capped at 460 watts across all rails combined. Available connectors determine which components can be powered simultaneously. Builders needing higher wattage or additional PCIe power cables must select a larger unit. Modern Standby compatibility requires a supporting motherboard and operating system.

Questions sur cet article

How loud is the fan on the KHACHIMO 460W ATX supply when the system runs all day?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, giving near-silent operation during typical all-day use.

Which power connectors must my build already provide for the H460EBM-00 to work?

The unit is a standard ATX power supply, so your motherboard needs a 24-pin ATX connector and the usual 4-pin or 8-pin CPU power connector.

Will this 460W Gold unit run stably with an older motherboard that lacks Modern Standby support?

Yes, Modern Standby compatibility is an extra feature; the supply delivers standard ATX power and works normally with legacy boards.
