ACE300F 300W ATX power supply

The KHACHIMO ACE300F is a 300W ATX power supply built for modern desktop PCs. It targets builders who value quiet operation and high efficiency in standard form-factor systems. The unit is new and carries 80 PLUS Gold certification for reduced energy waste.

80 PLUS Gold efficiency

This supply meets the 80 PLUS Gold standard, meaning it delivers high efficiency across typical loads. Lower power draw translates into less heat and quieter cooling. The Gold rating is the single spec that confirms the unit will run efficiently in daily use.

300W capacity with Modern Standby support

The 300W output comfortably handles mainstream CPUs and mid-range graphics cards in office or home builds. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Zero RPM fan mode keeps the system near-silent at low and medium loads. Builders needing more than 300W for high-end GPUs or multi-GPU setups should look elsewhere.

Questions about this item

What does the 300 W rating mean for a typical desktop build?

It delivers up to 300 W of continuous DC power to the motherboard, graphics card and drives, so it suits entry-level systems with integrated graphics or a modest dedicated GPU.

How does the 80 PLUS Gold certification affect daily use?

The unit meets 80 PLUS Gold efficiency targets, converting more wall power into usable DC power, which lowers electricity draw, reduces heat and allows the fan to stay off longer.

Will this ATX unit fit a standard mid-tower case?

Yes, it follows the ATX form factor, so it mounts in any case designed for a regular ATX power supply using the standard four screw holes.
