  • ATX form factor fits standard desktop builds

Compact ATX Power Supply for Modern Standby Systems

This 300 W continuous ATX unit carries 80 PLUS Gold certification and is built for PCs that use Modern Standby sleep states. It suits small-form-factor builds or upgrades where a lower-wattage, high-efficiency supply is required. The resonant LLC topology with DC-to-DC conversion delivers clean power and helps reduce coil whine.

Practical Limits of the ATX Form Factor

The 300 W continuous rating means the supply is not suited to configurations with discrete graphics cards or multiple high-power drives. Peak output reaches 400 W for short transients, but sustained loads above 300 W will exceed the design envelope. Zero RPM fan mode operates only at low and medium loads, so heavier workloads will engage active cooling.

300 W Continuous Output Decides Fit

The single specification that determines compatibility is the 300 W continuous power rating. Systems requiring more sustained power must select a higher-wattage unit. Buyers who need greater headroom for powerful GPUs or many peripherals cannot use this supply.

Questions sur cet article

Which wattage should I pick between the 300 W continuous and 400 W peak ratings?

The 300 W continuous rating is the sustained power the unit delivers; the 400 W peak covers short spikes, so size the PSU to your system's steady draw.

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

It certifies high efficiency across typical loads, reducing waste heat, lowering electricity cost and helping the fan stay off longer.

Does the ATX form factor fit every desktop case?

ATX is the standard desktop size, so it fits any case built for ATX power supplies; check your chassis specs for length clearance.
