480 W ATX power supply

The KHACHIMO DPP480-48-1 delivers 480 W of continuous power on a single 48 V rail rated at 10 A. It fits standard ATX bays and targets system builders who need a compact, high-efficiency unit for modern standby-capable platforms.

80 PLUS Gold efficiency and Zero RPM fan

Certified 80 PLUS Gold efficiency reduces waste heat and keeps internal temperatures lower during typical workloads. A Zero RPM fan mode stops the cooling fan completely at low and medium loads, while resonant LLC topology with DC-to-DC conversion minimises coil whine for quieter operation.

Modern Standby support for instant wake

Modern Standby compatibility enables extremely fast wake-from-sleep times and improves low-load efficiency. The resonant LLC and DC-to-DC design also allows deeper, more energy-efficient sleep states without sacrificing voltage stability.

Questions about this item

How is the KHACHIMO DPP480-48-1 installed, and what step is often missed?

Mount the ATX unit in the case with four screws, connect the 24-pin motherboard cable and the 4-pin or 8-pin CPU cable, then verify the 48 V output rails match your system’s 48 V requirement before powering on.

What maintenance or replacement will the DPP480-48-1 need later?

The 80 PLUS Gold certified unit uses a Zero RPM fan that stays off at low load; plan to clean dust from the fan intake yearly and replace the fan if bearing noise appears after several years.

What limit appears first under sustained use of this 480 W supply?

Continuous operation near the 10 A, 48 V maximum raises internal temperatures, so the protection circuits will throttle output before the 480 W rating is exceeded for long periods.
