KHACHIMO ATX power supply for modern standby

This KHACHIMO ATX power supply supports Modern Standby for extremely fast wake-from-sleep times and better low-load efficiency. It targets builders who want an 80 PLUS Gold unit that keeps energy use down while the system is idle or asleep. The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine. Zero RPM fan mode stops the fan at low and medium loads for near-silent operation.

Upgrade from bronze or non-standby units

Moving from an 80 PLUS Bronze or non-Modern-Standby supply cuts waste heat and lowers idle draw. The jump is worth it when you rely on sleep states and want the fan to stay off during light work. Buyers who need higher wattage than this model provides should look elsewhere.

Limits of ATX and Gold efficiency

ATX form factor fits standard cases but cannot exceed the physical envelope of the standard. 80 PLUS Gold guarantees efficiency at defined load points, not at every possible load. Modern Standby requires platform support from the motherboard and operating system to function.

Questions about this item

Does this ATX power supply fit a standard ATX case?

Yes, the unit follows the ATX form factor so it mounts in any standard ATX chassis using the four rear mounting screws.

What is the most common mistake when installing this power supply?

Forgetting to connect both the 24-pin motherboard cable and the 8-pin CPU cable before closing the case.

When should the cooling fan be cleaned on this unit?

Clean the fan intake with compressed air once a year or whenever dust buildup is visible, since the Zero RPM mode means the fan spins less often.
