Product information

Description

The Silverstone SX450-B 450 W is a compact SFX power supply unit designed for small-form-factor PC builds. It delivers up to 450 W total power, includes a 24-pin ATX motherboard connector and supports a wide AC input range of 90–265 V. The unit is finished in black, has an 80 mm cooling fan and comes with SATA power cables in lengths of 100, 200 and 300 mm. With 80 PLUS Bronze certification and compliance with the IEC 62368-1 safety standard, the SX450-B provides efficient and standards-compliant power delivery for reliable system operation.

Advantages

The SX450-B combines 80 PLUS Bronze efficiency with a quiet 80 mm fan to reduce energy losses and keep noise low. Its Active PFC circuitry improves power factor and overall efficiency, while the Forward + DC-to-DC topology enhances voltage stability and supply reliability. Compliance with the IEC 62368-1 safety standard ensures the unit meets current safety requirements.

Suitable for

  • Compact SFX and small-form-factor gaming or workstation PCs
  • Home and office systems requiring a reliable 450 W power source
  • Builds where 24-pin ATX compatibility and short PSU depth are needed

Key specifications

  • Total power: 450 W
  • Efficiency: 80 PLUS Bronze (approx. 85%)
  • Motherboard connector: 24-pin ATX
  • AC input range: 90–265 V
  • Fan diameter: 80 mm
  • Dimensions (W × D × H): 125 × 100 × 63.5 mm
  • Weight: 0.91 kg
  • Colour: Black
  • Safety standard: IEC 62368-1

How to use

Install the SX450-B into a compatible SFX or SFX-to-ATX adapter bay following your chassis manual. Connect the 24-pin ATX cable to the motherboard and attach SATA, peripheral or PCIe connectors as required by your components. Ensure the AC mains input matches the specified 90–265 V range and secure the PSU before powering on the system. Allow clearance for airflow around the 80 mm fan and route cables to avoid obstructing case ventilation.

Usage recommendations

For stable operation, use the SX450-B in systems where the total continuous load does not exceed the rated 450 W. Maintain case airflow, inspect and clean the fan periodically, and avoid operating the PSU in high-temperature or high-dust environments to prolong service life.
