## Long description

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.
Advantages
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.
Suitable for
Small form factor (SFF) desktop PC builds
Home or office systems requiring quiet operation
Systems needing a compact 300 W PSU with PCI‑E 6‑pin support

How to use
Install the TX300 into a compatible TFX chassis following the case manufacturer’s mounting instructions.

Ensure proper cable routing to maintain airflow and verify AC input range matches local mains before first power‑on.
Usage recommendations
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.
