ATX 300 W Power Supply

This KHACHIMO ATX power supply delivers 300 W of continuous power for desktop PCs. It carries 80 PLUS Gold certification for high efficiency at typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

System Builders Prioritising Efficiency

The unit suits builders who want Gold-rated efficiency, low heat output and near-silent running at light loads. Its Zero RPM fan mode stops the fan entirely at low and medium loads for quiet operation. Buyers needing more than 300 W for high-end graphics cards or multi-GPU configurations should look at higher-capacity units. Systems requiring redundant or server-grade power supplies are not addressed by this model.

300 W Continuous Output Rating

The single specification that decides fit is the 300 W continuous output rating. Match this figure against the total power draw of your CPU, GPU, drives and peripherals under full load. If the system's peak demand exceeds 300 W, a higher-wattage supply is required. No other wattage figure from the product name applies to this unit's rated delivery.

商品問答

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

The 80 PLUS Gold certification confirms high efficiency across typical loads, which lowers electricity draw, reduces heat output and lets the fan stay off longer.

What does the ATX type tell me about motherboard compatibility?

ATX is the standard desktop form factor, so the unit fits regular ATX cases and provides the 24-pin main connector plus CPU and peripheral cables expected by modern boards.

Will the 300 W rating handle a mid-range graphics card and CPU together?

At 300 W the supply is designed for office or entry-level builds; a discrete mid-range GPU plus a modern CPU can exceed that budget, so check total system draw before deciding.
