460W ATX Gold power supply

The KHACHIMO 8024F S4820 is a new ATX power supply rated at 460W with 80 PLUS Gold certification. It targets system builders who want high efficiency and quiet operation in a standard desktop chassis. Modern Standby compatibility ensures rapid wake times and improved low-load efficiency for contemporary operating systems.

Replaces older group-regulated units

Swapping a legacy group-regulated PSU for this resonant LLC design with DC-to-DC conversion delivers cleaner power rails and reduced coil whine. The upgrade is worth it when the existing unit lacks Gold efficiency, produces audible fan noise at idle, or cannot support modern sleep states. Systems that frequently enter sleep benefit most from the faster wake capability.

Fits standard ATX builds

The unit mounts in any ATX-compatible case and uses the resonant LLC topology to free up thermal headroom by running cooler at typical loads. Zero RPM fan mode eliminates fan noise during light workloads, leaving the case airflow budget for the CPU and GPU coolers. Builders who need higher wattage or a different form factor should look elsewhere.

Questions about this item

Does the 460W ATX unit fit a standard ATX case opening?

Yes, it uses the standard ATX form factor so it mounts in any case with an ATX power-supply cut-out.

Which cables must be connected for a basic boot?

Connect the 24-pin ATX motherboard cable and the 4- or 8-pin CPU power cable; the unit will not start without both seated fully.

What part wears out first and how do I know?

The cooling fan bearing is the main wear item; rising noise or a fan that stops spinning under load signals it needs replacement.
