KHACHIMO RPT 300W Power Supply MPR3001

SKU CH-Z3W1-4T32P

A 300 W ATX power supply with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion for quiet, stable power

  • TypeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold certification lowers energy draw and heat output
  • Zero RPM fan mode keeps the system silent at low load
  • Resonant LLC topology with DC-to-DC conversion delivers stable voltage and reduces coil whine
  • ATX form factor fits standard desktop cases

Ideal for Modern Standby Builds

The KHACHIMO RPT 300W unit is an ATX power supply designed for systems that rely on Modern Standby sleep states. Its 300 W output suits compact or low-power configurations where efficient idle behaviour matters more than high peak capacity. Builders seeking a Gold-rated unit for a small-form-factor PC will find the specifications match those needs.

Thermals Noise and Power Draw

80 PLUS Gold certification confirms high efficiency across typical loads, which reduces waste heat and keeps internal temperatures lower. The Zero RPM fan mode stops the cooling fan completely at low and medium loads, delivering near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion further cuts coil whine and supports deeper, more efficient sleep states.

Replaces Older Low-Efficiency Units

This supply upgrades from older ATX units that lack Modern Standby support or Gold-level efficiency, especially where wake-from-sleep speed and silent idle are priorities. The jump is worth it when the build demands fast resume times and quiet low-load running. It is not suited for systems requiring higher wattage headroom or multiple high-power graphics cards.

Perguntas sobre este artigo

How do I install this 300 W ATX power supply and which cable is often missed?

Fit the unit into the ATX bay with four screws, attach the 24-pin motherboard connector and the 4/8-pin CPU connector, then add any PCIe cables your graphics card needs; the step most builders forget is seating the CPU power plug firmly near the socket.

What maintenance will the MPR3001 need over time?

Dust the intake grill and fan blades every few months with compressed air; the Zero RPM Fan Mode means the fan stops at low load, so dust settles faster and can unbalance the bearing when it spins up again.

What limit appears first when the supply runs at high load for a long period?

The 300 W total output ceiling is reached before any thermal throttle, so sustained draws near that rating will trigger over-power protection and shut the unit down.
