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

520W ATX Power Supply

The KHACHIMO SPR1C520 is a 520W ATX power supply built for modern desktop PCs. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine.

Upgrade from older group-regulated units

This supply replaces legacy group-regulated designs that lack DC-to-DC conversion and deep sleep support. The jump is worth it when building a system that uses Modern Standby or demands quieter operation at idle. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running. Gold-rated efficiency lowers power draw and heat output compared to Bronze or unrated units.

Builders prioritising efficiency and silence

Suits system builders who want Gold-class efficiency, Modern Standby support and a fan that stays off at light loads. The 520W capacity fits mainstream CPUs and single mid-range GPUs. Buyers needing higher wattage for multi-GPU setups or extreme overclocking should look at higher-capacity models. Those requiring fully modular cabling or a longer warranty period should consider other options.

Questions sur cet article

What ATX form-factor space does the KHACHIMO 520W unit occupy in the case?

It uses the standard ATX footprint, so it fits any chassis designed for a regular ATX power supply.

How is the SPR1C520 installed, and which cable step is often missed?

Mount it with four screws, connect the 24-pin motherboard and CPU power cables, then attach GPU and drive cables; the step most people forget is plugging in the CPU 4+4-pin connector near the socket.

What part will need attention first on this 80 PLUS Gold model?

The cooling fan is the only moving component; if it eventually becomes noisy or stops spinning, replacing the fan restores quiet operation.
