500W 80 PLUS Gold ATX Power Supply

This KHACHIMO unit delivers 500 watts of continuous power through an ATX form factor. It carries 80 PLUS Gold certification for high efficiency, lower power draw and reduced heat output. The resonant LLC topology with DC-to-DC conversion provides clean, stable voltage rails and helps minimise coil whine.

Systems needing Modern Standby and quiet idle

The supply suits builds that rely on Modern Standby for extremely fast wake-from-sleep and improved low-load efficiency. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. It is not suited for configurations requiring more than 500 watts or for servers needing redundant power modules.

Check ATX fit and cable reach before ordering

Verify that your chassis accepts a standard ATX power supply and that the fixed cables reach your motherboard, CPU and graphics connectors. Confirm the total system power draw stays within the 500 watt rating. Ensure the rear mounting holes align with your case layout.

商品問答

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

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

Will the Zero RPM fan mode still engage if I keep an older mechanical hard drive that spins up at boot?

Yes, the fan remains off at low and medium loads, so brief spin-up current from legacy drives will not force the fan to start.

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

Monitor power draw at the wall while the system idles; the Gold rating means the supply should draw noticeably less AC power for the same DC load than a lower-rated unit.
