KHACHIMO ATX power supply for modern standby PCs

This KHACHIMO ATX power supply delivers 15.5V at 4.8A and carries 80 PLUS Gold certification for high-efficiency operation. It is built for systems that use Modern Standby, offering extremely fast wake-from-sleep times and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. It suits builders who want efficient, quiet power for contemporary sleep states.

Standard ATX installation with zero RPM fan mode

The unit follows the standard ATX form factor, so it fits regular mounting points and uses familiar connector layouts. At low and medium loads the cooling fan stops completely, enabling near-silent operation without extra configuration. The most common issue is forgetting to seat the main power and CPU cables fully, which can prevent boot or cause instability. Ensure all modular connections click into place on both the PSU and component sides.

Check ATX compatibility

Verify that your case accepts a standard ATX power supply and that your motherboard supports Modern Standby to use the fast wake features. Confirm the 15.5V 4.8A output matches the power requirements of your specific hardware configuration. The 80 PLUS Gold rating ensures efficient performance, but total wattage must suit your build. This unit is not for systems needing a different form factor or higher total power delivery.

Questions about this item

How can I confirm the power supply is operating correctly after installation?

Verify the system wakes from sleep almost instantly and runs quietly under light loads; the fan should stay off until the unit reaches medium load.

Which cables and accessories are included with the KHACHIMO 15.5V 4.8A SR 92B370, and what must be purchased separately?

The box contains the ATX power supply unit itself; all required power cables are permanently attached, so no separate cable kit is needed.

How do I decide between the available versions or capacities of this model?

This model is offered in a single 15.5 V 4.8 A configuration identified by SR 92B370, so there are no alternative capacities to choose from.
