388W ATX Power Supply

The KHACHIMO DCJ3883-01P delivers 388 watts of continuous power in a standard ATX form factor. It is suited for mainstream desktop builds and workstation replacements that require efficient, reliable energy delivery without excess capacity. The unit carries 80 PLUS Gold certification for verified high-efficiency operation across typical load ranges.

Sustained load behaviour

Under continuous demand the resonant LLC topology with DC-to-DC conversion maintains clean, consistent voltage regulation and reduces coil whine. The 80 PLUS Gold rating ensures lower power draw, less waste heat and quieter cooling during extended work sessions. Zero RPM fan mode keeps the fan off at low and medium loads for near-silent running.

Upgrade context

This supply replaces older Bronze-rated or uncertified units where efficiency, noise and Modern Standby support are concerns. The jump is worthwhile when a system needs faster wake-from-sleep, reduced idle power and quieter operation under typical workloads. It is not for builds requiring higher wattage headroom or multiple GPU power connectors.

Questions sur cet article

How loud and hot does the 388W unit get during all-day use?

The 80 PLUS Gold certification means high efficiency, so less waste heat and lower fan speeds. Zero RPM mode stops the fan completely at low and medium loads for near-silent operation, and the resonant LLC topology with DC-to-DC conversion reduces coil whine.

What must my system already have for this ATX supply to work?

Your case needs a standard ATX PSU bay and your motherboard a 24-pin ATX power socket; the unit follows the ATX form factor so it fits existing mounting points and cable routing.

Will the Modern Standby feature work with my older motherboard?

Modern Standby requires a compatible motherboard and OS to enable the faster wake-from-sleep and improved low-load efficiency; on non-compatible hardware the supply still delivers clean power via its resonant LLC topology but the fast sleep states will not activate.
