KHACHIMO 500W ATX Power Supply

The KHACHIMO DPS-500AB-51A is a 500W ATX power supply built with resonant LLC topology and DC-to-DC conversion for clean, consistent power delivery. It carries 80 PLUS Gold certification for high efficiency, lower consumption and reduced heat. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. A Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Suited for efficient, quiet PC builds

This unit suits builders who want Gold-rated efficiency, Modern Standby support and silent running at typical desktop loads. The resonant LLC design reduces coil whine for quieter operation. Systems needing more than 500W of continuous power should look at higher-capacity units. Builds requiring specific cable configurations not listed here will need to verify compatibility separately.

500W continuous capacity with Gold headroom

The 500W rating delivers ample headroom for mainstream CPUs and mid-range graphics cards under full load. Gold efficiency keeps waste heat and noise low across the load range. At sustained loads above 500W the protection circuits will engage, so heavier workstations or multi-GPU setups will exceed this unit's capability.

Questions about this item

What motherboard power connectors must my board provide for this ATX supply to work?

The unit uses a standard ATX form factor, so your motherboard needs a 24-pin main power connector and a 4-pin or 8-pin CPU power connector.

Will the Zero RPM fan mode stay silent when paired with an older GPU that draws constant low power?

At low and medium loads the cooling fan switches off entirely, so even a legacy graphics card idling at modest wattage should keep the supply in its silent Zero RPM state.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Under typical loads the PSU will run cooler and quieter; you can verify Gold-level efficiency by measuring AC input versus DC output with a power meter and checking the ratio matches the 80 PLUS Gold standard.
