Voeding Thermaltake Smart BX3 750 W

The Thermaltake Smart BX3 750 W power supply is an ATX 3.1–compatible unit designed for mainstream PC builds that require reliable, entry-level power delivery. It provides 750 W total output, an 80 PLUS Bronze efficiency rating, a 120 mm fluid-bearing cooling fan with Smart Zero Fan control, a high-quality 105°C main capacitor and a single +12V rail with DC-to-DC regulation. The unit has a non-modular flat cable design in black and measures 150 mm x 86 mm x 140 mm.

Advantages

The Smart BX3 750 W combines ATX 3.1 compliance with up to 200% power excursion capability and required timing standards, ensuring compatibility with modern motherboards. The 80 PLUS Bronze efficiency rating and high-temperature main capacitor improve stability and long-term reliability. A 120 mm fluid-bearing fan with Smart Zero Fan operation reduces noise at low loads while providing effective cooling under load. The single high-amperage +12V rail and DC-to-DC topology deliver stable voltages for system components.

Suitable for (tasks / use cases)

• Mainstream gaming and office PC builds requiring up to 750 W of power
• Systems that need ATX 3.1 compatibility and stable +12V delivery
• Budget-conscious builds prioritizing straightforward cable routing with flat, non-modular cables

How to use

Install the Thermaltake Smart BX3 750 W into a compatible ATX chassis following the motherboard and case manufacturer instructions. Connect the 24-pin ATX, CPU 4/8-pin, PCIe, SATA and peripheral connectors to the appropriate components, ensuring secure seating of each connector. Ensure the AC mains cable is connected to a properly grounded outlet within the 100–240 V range before powering the system. If the system operates at low load, the Smart Zero Fan will keep the fan stopped until a higher load threshold is reached.

Recommendations

Use this PSU in systems whose combined component power draw does not exceed 750 W. For improved airflow and cable management, route the flat black cables to avoid blocking case fans and keep connections secure. Do not exceed the specified input voltage range and follow safety guidelines when installing or servicing the unit.
