Purpose-built low-wattage ATX unit

The KHACHIMO PSR75-12A is a 75W ATX switching power supply intended for compact or legacy systems that draw little power. It suits office PCs, thin clients or embedded builds where a full-size high-wattage unit would be oversized.

Build integration and space savings

Its ATX form factor fits standard chassis cut-outs while the modest 75W output leaves headroom on the mains circuit and reduces cable bulk inside small enclosures. The unit frees internal volume for airflow or additional drives without demanding a larger case footprint.

Thermals, noise and power draw

Rated at 75W continuous output, the supply runs at low load in typical office workloads, keeping heat output minimal. A lightweight switching topology aids efficiency, so fan speeds stay quiet during normal operation and overall power draw remains close to the rated ceiling.

Questions about this item

What is the maximum continuous output of the PSR75-12A before it hits its limit?

The unit is rated for 75 W continuous output; sustained loads above that will trigger its protection circuitry.

How much heat and fan noise should I expect when the PSR75-12A runs at full load all day?

As a 75 W switching supply it generates modest heat; the built-in fan runs quietly at low RPM under typical loads.

Which motherboard power connectors must my board already have to use this ATX supply?

It provides the standard 20+4 pin ATX main connector plus 4-pin CPU and peripheral leads for typical boards.
