KHACHIMO 720W ATX Supply

This KHACHIMO unit delivers 720W of continuous power in a standard ATX form factor. It is built for Alphaserver ES40 and ES45 platforms requiring the API-7650 pinout. System integrators replacing a 30-49448-01 module will find a direct electrical match. Buyers needing redundant or hot-swap frames should look elsewhere.

80 PLUS Gold Thermals

The 80 PLUS Gold rating confirms high efficiency across typical loads, reducing waste heat and overall power draw. A resonant LLC topology with DC-to-DC conversion supplies clean voltage regulation and helps suppress coil whine. Zero RPM fan mode stops the fan completely at low and medium loads for silent running. Heavy sustained loads will spin the fan to maintain safe temperatures.

Modern Standby Connectivity

Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. The fixed cable harness matches the original server pinout, so no adapter looms are required during installation. ATX mounting points align with standard chassis screw patterns. Builds requiring modular cables or non-standard form factors cannot use this unit.

Questions about this item

How do I install the KHACHIMO 720W unit in an AlphaServer ES40 or ES45, and what step is often missed?

Slide the supply into the chassis until the latch clicks, then secure the retention screw; the step often missed is fully tightening that screw so the unit stays seated under vibration.

What maintenance will the API-7650 30-49448-01 need later?

Clean the intake vents with compressed air every few months; the Zero RPM fan mode means the fan spins less, but dust still builds up and can restrict airflow at higher loads.

Which limit appears first when the 720W supply runs at sustained load?

The 80 PLUS Gold efficiency curve is validated up to the rated 720W; continuous operation beyond that rating will trip the over-power protection before thermal limits are reached.
