Thermaltake Smart BX3 Bronze 650W SMPS

The Thermaltake Smart BX3 Bronze Series is engineered to deliver dependable power, modern standards, and quiet operation at an affordable price point. Built to meet the latest ATX 3.1 specifications, this power supply series ensures stable performance, higher efficiency, and improved durability—making it ideal for entry-level and mid-range gaming or productivity systems.

Unmatched Reliability with ATX 3.1 Compliance

Designed to fully support ATX 3.1 standards, the Smart BX3 series is capable of handling up to 200% power excursion, maintaining excellent efficiency at low loads, and meeting all required PSU timing guidelines. This ensures smoother performance during sudden GPU or CPU power spikes and guarantees long-term system stability with next-gen hardware.

Quiet Operation with Smart Zero Fan Technology

The PSU features a 120mm Fluid Dynamic Bearing (FDB) fan, optimized for superior airflow and long operational life.

With Smart Zero Fan, the fan remains completely off until the system reaches around 20% load, ensuring silent operation during light or idle usage. Noise is minimized while cooling performance stays reliable when needed most.

High-Quality Japanese Main Capacitor

Built with a 105°C/221°F high-grade main capacitor, the Smart BX3 ensures exceptional longevity, durability, and stable output even under heavy workloads. This premium component increases reliability and prevents voltage fluctuations over time.

Strong Single +12V Rail & DC-to-DC Conversion

A powerful single +12V rail design provides consistent and uninterrupted power delivery to demanding components such as CPUs and GPUs.
The DC-to-DC circuit design enhances voltage regulation, improves efficiency, and ensures stable operation across all output rails.
