  • TypeATX
  • Fast wake-from-sleep with Modern Standby support

  • 460 W ATX capacity powers mainstream builds reliably

Capacity and form factor

The KHACHIMO EFRP-462 is a 460W ATX power supply built for mainstream desktop builds. It suits system integrators and home users who need reliable, efficient power for mid-range components without over-specifying capacity.

Efficiency, cooling and acoustics

80 PLUS Gold certification delivers high efficiency, reducing power draw, heat output and fan demand. A Zero RPM mode stops the fan completely at low and medium loads for near-silent running, while resonant LLC topology with DC-to-DC conversion keeps output clean and minimises coil whine.

Upgrade context and fit

This unit replaces older, lower-efficiency supplies in standard ATX cases where 460W covers the installed hardware. The jump is worthwhile when moving from uncertified or Bronze units to gain quieter operation, better low-load efficiency and Modern Standby support for faster wake times.

Questions about this item

How do I install the EFRP-462 and what step is often missed?

Mount the unit in a standard ATX case with four screws, connect the 24-pin motherboard and CPU power cables, then verify the PSU power switch is set to on before pressing the case button.

What maintenance will the EFRP-462 need over time?

The fan stops at low load under Zero RPM mode, so dust builds up more slowly; clean the intake grill with compressed air when you service the rest of the PC.

What limit appears first during sustained heavy load on the EFRP-462?

The 460 W continuous output rating is the hard ceiling; exceeding it triggers over-power protection and shuts the unit down.
