Power Supply Unit Silverstone TX300 300 W
The SilverStone TX300 is a compact TFX power supply unit delivering 300 W continuous output, designed for small form factor PC builds. It supports AC input from 90 to 264 V, includes a 24-pin ATX motherboard connector and a silent 80 mm cooling fan, and carries an 80 PLUS Bronze efficiency rating. The unit is finished in black and provides stable operation at up to 40°C for 24/7 use, with a single PCI‑E 6‑pin connector and sleeved cables for neat cable routing.
The TX300 combines a compact TFX form factor with 300 W continuous output at 40°C and 80 PLUS Bronze efficiency to balance size and performance. An 80 mm fan optimized for low noise operation (minimum 18 dBA) and sleeved cables improve system appearance and airflow management. Active PFC and support for standard TFX mounting ensure compatibility with many small chassis while maintaining reliable voltage delivery for 24/7 operation.
Install the TX300 into a compatible TFX chassis following the case manufacturer’s mounting instructions. Connect the 24‑pin ATX cable to the motherboard and attach the SATA and peripheral connectors to drives as needed. Use the PCI‑E 6‑pin connector for a compatible add‑on card if required. Ensure proper cable routing to maintain airflow and verify AC input range matches local mains before first power‑on.
For reliable long‑term operation, keep the PSU intake and exhaust clear of dust and allow sufficient case ventilation. Use the TX300 in systems whose total power draw stays comfortably below 300 W to maintain headroom and component longevity.
