300W ATX power supply for basic builds

This KHACHIMO unit delivers 300 watts through a standard ATX form factor and a 24-pin main connector. It suits office PCs, home-theatre systems or entry-level desktops that draw modest power. Buyers who need more headroom for discrete graphics cards or multiple drives should look elsewhere.

Thermals noise and power draw

The supply is tested working and built to good quality standards for its class. Under typical office loads the fan runs quietly and heat output remains low. Efficiency at normal use keeps mains draw close to the rated output without excess waste.

Questions about this item

How do I install this 300W ATX power supply and which step is commonly missed?

Mount the unit in the case with four screws, connect the 24-pin ATX motherboard plug and the CPU power cable, then remember to flip the rear I/O switch to the on position before pressing the case power button.

What maintenance or replacement will this 300W ATX power supply need later?

Clean dust from the intake grill and fan blades every few months with compressed air; if the fan becomes noisy or voltages drift under load, replace the entire unit as internal capacitors are not user-serviceable.
