500W ATX Power Supply for Modern Standby Systems

The KHACHIMO PRM500-1 is a 500W ATX power supply built with Resonant LLC topology and DC-to-DC conversion. It delivers clean, consistent power while reducing coil whine. The unit holds 80 PLUS Gold certification for high efficiency and lower heat output. It is designed for systems requiring fast wake-from-sleep capability.

Suitable for Quiet Builds with Modern Standby

This unit suits builders who prioritise silent operation through its Zero RPM fan mode at low and medium loads. It also fits systems that depend on Modern Standby compatibility for rapid wake times. Buyers needing higher wattage for multi-GPU configurations or extreme overclocking headroom should look at higher-capacity units instead.

80 PLUS Gold Efficiency Rating

The 80 PLUS Gold certification confirms high-efficiency operation across typical loads, reducing power consumption and keeping temperatures lower. This efficiency level supports the Modern Standby sleep states enabled by the platform topology. It is the key specification for verifying the unit meets its efficiency and thermal claims.

Questions about this item

Does the PSU ship with the modular cables and mounting screws, or do I need to buy them separately?

The unit is supplied as the power supply itself; modular cables and mounting screws are not included and must be sourced separately.

Should I choose this 500 W model or look for a higher-wattage unit?

Select the 500 W version if your build’s peak draw stays below that level; a higher-wattage model is only needed for systems that demand more power.

What does the 80 PLUS Gold rating actually deliver in a running PC?

It means the supply meets the Gold efficiency targets, so it wastes less electricity, runs cooler and keeps the fan off longer under light loads.
