Product information

Description

The THERMALTAKE 850W Smart BX3 Pro SE is an ATX power supply designed to provide stable continuous power for desktop computers. With an 850W rated output and a single +12V rail, it is built to support high-current components such as modern CPUs and GPUs. Modular cables allow for neater cable management and simpler installation, making it suitable for gaming systems, creative workstations and general-purpose desktops that require reliable power delivery and basic protection features.

Advantages

This power supply offers an 850W capacity that covers demanding components and multiple drives while a single +12V rail design simplifies power distribution for high-current devices. Modular cables reduce clutter inside the chassis and improve airflow. The unit includes standard protection mechanisms to safeguard connected hardware and is designed for continuous operation under typical desktop loads.

Suitable for

  • Gaming PCs with mid-to-high power graphics cards
  • Content creation workstations and rendering rigs
  • Upgrade projects requiring higher wattage and cleaner cable routing
  • General desktop systems with multiple storage drives and peripherals

Key specifications

  • Form factor: ATX
  • Rated output power: 850 watts
  • Output topology: single +12V rail for high-current delivery
  • Cabling: modular cable system for detachable connectors
  • Efficiency: designed for typical desktop efficiency levels (labeling depends on unit variant)
  • Cooling: integrated fan for active thermal management
  • Protection features: provides over-voltage, over-current and short-circuit protections

How to use

Install the power supply into a compatible ATX case following standard safety practices: power off and unplug the system before installation, position the unit so its fan and ventilation align with the case airflow, secure it with screws, and connect the required motherboard, CPU, GPU and peripheral power connectors. Use only the modular cables provided by the manufacturer and attach them as needed to power drives and accessories. Verify all connections before powering on the system.

Usage recommendations

For stable, long-term operation, ensure adequate case airflow and avoid blocking the PSU intake or exhaust. Select connectors appropriate for your components and route modular cables to maintain unobstructed airflow. When building high-power systems, confirm total system power draw remains below the supply’s 850W rating and distribute loads across connectors as recommended by the case and component manufacturers.
