KHACHIMO

KHACHIMO 36-75V 12V 33A ATX Power Supply 80 PLUS Gold

SKU CH-1CMV-2MXDZ

An ATX power supply with 80 PLUS Gold efficiency, 12 V 33 A output, 36-75 V input, Modern Standby support, zero-RPM fan mode and resonant LLC topology with DC-to-DC conversion

  • TypeATX
  • Modern Standby gives fast wake times and better low-load efficiency
  • 80 PLUS Gold certified for high efficiency, lower consumption and cooler running
  • Zero RPM fan mode stops the fan at low and medium loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 12 V rail rated at 33 A for strong single-rail performance

Modern Standby Ready Power

This ATX power supply targets desktop builders who need Modern Standby compatibility for rapid wake-from-sleep and improved low-load efficiency. It suits systems that spend long periods in sleep states while keeping power draw minimal. It is not for users who require higher wattage headroom or multiple GPU power connectors beyond the single 12 V rail design.

Thermals Noise and Efficiency

80 PLUS Gold certification delivers high efficiency that lowers overall power consumption and reduces waste heat. Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion further cuts coil whine and supports deeper sleep states without extra noise.

Topology and Sleep Benefits

The resonant LLC design with DC-to-DC conversion provides clean, consistent power output across the 36 V to 75 V input range on the 12 V rail rated at 33 A. This topology enables more energy-efficient sleep states and faster wake times demanded by Modern Standby. Builders without Modern Standby motherboards will not gain these specific sleep-state advantages.

Highlights

  • Zero RPM fan mode stops the fan at low and medium loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 12 V rail rated at 33 A for strong single-rail performance

Questions about this item

How do I install the KHACHIMO 12V 33A ATX power supply and what step is often missed?

Mount the unit in a standard ATX case, connect the 24-pin motherboard and CPU power cables, then enable Modern Standby in the BIOS so the fast wake-from-sleep and low-load efficiency features work correctly.

What maintenance will the KHACHIMO 80 PLUS Gold power supply need later?

Periodically clean dust from the fan intake; the Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing bearing wear, but the fan will eventually require replacement after extended high-load use.

What limit appears first on the KHACHIMO 36-75V input supply under sustained load?

The 12 V rail is rated at 33 A; sustained draw near that level will hit the current limit before the 80 PLUS Gold efficiency curve or thermal protection engages.
