300W ATX Power Supply

The KHACHIMO ACE300F is a 300W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep transitions. Resonant LLC topology with DC-to-DC conversion delivers clean, stable power output. A zero RPM fan mode keeps the unit silent at low and medium loads.

Ideal for Efficient Low-Power Builds

This unit suits builders assembling office PCs, home-theatre systems or compact rigs where 300W of Gold-rated power is sufficient. The near-silent fan profile benefits noise-sensitive environments. It is not for configurations that demand higher wattage headroom or multiple high-draw graphics cards. Buyers needing greater capacity should look elsewhere.

80 PLUS Gold Efficiency

The 80 PLUS Gold rating confirms high efficiency across typical loads, reducing power draw, heat and acoustic output. Combined with the resonant LLC design, it enables deeper, more energy-efficient sleep states supported by Modern Standby. This single specification determines whether the supply matches your build's efficiency and power requirements.

Perguntas sobre este artigo

Is the ACE300F the right capacity for my build?

The ACE300F delivers 300W of continuous power, suitable for entry-level office PCs or basic home systems with integrated graphics and modest components.

What does the 80 PLUS Gold rating mean for daily use?

It guarantees at least 80% efficiency at typical loads, so less electricity is wasted as heat, keeping the unit cooler and quieter during normal operation.

How does the ATX form factor affect installation?

The standard ATX dimensions let it fit most mid-tower and full-tower cases, using the regular 24-pin motherboard and 4/8-pin CPU power connectors.
