Basic ATX power supply for entry builds

The KHACHIMO EPR-301R is a 300W ATX power supply suited to basic desktop builds and office refresh projects. It delivers standard ATX output for systems that do not require high-wattage components. The unit is supplied new and tested working by the manufacturer.

Steady output under continuous load

Rated at 300W, the supply is designed to maintain its rated output during sustained workloads rather than only in short bursts. This behaviour supports typical office applications and light multimedia tasks without unexpected shutdowns. The design targets consistent voltage regulation across the operating range.

Low-noise operation and modest power draw

In normal use the unit runs quietly thanks to a temperature-controlled fan that spins only as fast as needed. Power draw at the wall reflects the efficiency of a 300W design under typical loads, keeping electricity costs modest for always-on desktops. The ATX form factor fits standard cases without special clearance concerns.

Questions about this item

How much heat and fan noise should I expect from the 300W EPR-301R running continuously?

The 300W EPR-301R is an ATX power supply tested as working; typical ATX units at this wattage run a temperature-controlled fan that stays quiet under light load and spins faster only when sustained power draw approaches the 300W rating.

Which motherboard and drive connectors must my build already have to use the EPR-301R?

The EPR-301R follows the ATX form factor, so it fits standard ATX cases and connects to a 24-pin motherboard socket plus the usual peripheral leads expected on an ATX unit.

Will the EPR-301R power an older system that still uses a 20-pin main connector and IDE drives?

The EPR-301R is an ATX supply first listed in March 2024; it provides the modern 24-pin main connector, so an older 20-pin motherboard would need an adapter, and any IDE drives would require Molex-to-IDE adapters.
