Product information

Description

The Silverstone ST30SF 300W is a compact SFX power supply unit intended for small-form-factor PC builds. This 300 W PSU provides a single 20+4 pin ATX motherboard connector, active cooling via a 92 mm fan, and 80 PLUS Bronze efficiency. It accepts an AC input voltage range of 90–264 V at 47–63 Hz and ships with SATA power leads of 100, 200 and 300 mm. Its small enclosure (125 mm × 100 mm × 63.5 mm) and black finish are suited to space-constrained systems that require reliable, continuous power delivery.

Advantages

The unit combines a compact SFX form factor with 80 PLUS Bronze efficiency, delivering up to 300 W in a small footprint. Active cooling with a 92 mm fan helps maintain stable temperatures under typical load levels. The wide AC input range supports international mains voltages and the included SATA power cables of varying lengths simplify internal cable routing. The black finish and 1 kg weight make the PSU easy to install in many small enclosures.

Suitable for

  • Mini-ITX or other small-form-factor desktop PC builds
  • Home theater PCs (HTPC) and compact multimedia systems
  • Office workstations with modest power requirements
  • Replacement or upgrade in cases that support SFX power supplies

How to use

Install the Silverstone ST30SF into a compatible SFX or SFX-to-ATX adapter-equipped case according to the case manufacturer’s instructions. Connect the 20+4 pin ATX connector to the motherboard and route the provided SATA power cables to storage devices as needed. Ensure the AC mains input is within the specified 90–264 V range and that the case allows adequate airflow for the 92 mm fan. After connections are secured, power on the system and verify stable operation under typical workload conditions.

Usage recommendations

Use this PSU in systems with total component power draw within the 300 W rating and maintain unobstructed airflow around the fan. For higher-power components or overclocked systems, consider a higher-wattage unit. Periodically inspect cables and connectors for secure seating and dust accumulation to preserve cooling efficiency and long-term reliability.

Noise level: Not only energy saving helps to protect the environment but also noise level reduction. Noise level reduction up to 3 dB really means noise level reduction in 2 times. For example, a device with noise level 39 dB (А) will be two times quieter than a devise with a noise level 42 dB (А). Energy-saving certificate that shows noise level plays the role of an additional objective indicator basing on which You can successfully choose a product.
