300 W ATX Power Supply

The KHACHIMO DPS-300AB-80 A is a 300 W ATX power supply built for compact desktop systems and office workstations. It delivers reliable power for everyday computing tasks and supports modern sleep states for quick resume times.

Upgrading from basic OEM units

Replacing a standard unrated or bronze-rated supply with this 80 PLUS Gold unit reduces power draw, heat output and acoustic noise. The jump is worth it when building or refreshing a system that spends long periods at idle or light load.

Capacity and headroom

The 300 W rating comfortably handles integrated graphics platforms, entry-level discrete cards and typical office peripherals. Headroom diminishes with high-end GPUs, multiple storage arrays or heavy overclocking scenarios.

Questions about this item

Does the KHACHIMO 300W ATX unit fit a standard ATX case opening?

Yes, the DPS-300AB-80 A uses the standard ATX form factor so it aligns with the regular case cut-out and four mounting holes.

How do I connect the 24-pin ATX cable without bending pins?

Route the main 24-pin connector straight into the motherboard socket, press evenly until the latch clicks, and avoid forcing it at an angle.

When should I clean the fan on this 300W Gold power supply?

Use compressed air to clear dust from the fan grille once a year; the Zero RPM mode means the fan spins less, so buildup is slower.
