Introduction
The Thermaltake Smart BX1 650W 80 PLUS Bronze Power Supply (PS-SPD-0650NNFABD-4) is designed for users looking for a dependable power supply for everyday desktops, productivity systems and compatible gaming PCs. Its 650W rated output offers a practical power foundation for systems with suitable CPU and graphics-card requirements.
This DC-to-DC version combines 80 PLUS Bronze efficiency with active Power Factor Correction and DC-to-DC conversion. The design supports stable voltage regulation across changing system loads, making it a useful feature for a variety of mainstream PC configurations.
A 120mm hydraulic bearing fan provides active cooling, while the black low-profile cables help simplify cable routing and keep the interior of the cabinet organised. The PSU uses a conventional non-modular design, with all cables permanently attached.
With a compact 140mm PSU depth and a five-year manufacturer warranty, the Smart BX1 is a practical option for compatible budget-conscious desktop builds.
Key Features
650W Continuous Power
Provides 650W of rated output, with up to 649.2W available on the +12V rail for compatible processor and graphics-card power requirements.
80 PLUS Bronze Efficiency
Bronze-certified power conversion helps reduce energy lost as heat compared with less efficient designs under comparable operating conditions.
DC-to-DC Conversion
The DC-to-DC design supports voltage regulation and stable operation as component loads vary across the system.
120mm Hydraulic Bearing Fan
The cooling fan uses intelligent RPM control to adjust airflow according to thermal requirements and support quieter operation during lighter workloads.
Multiple Power Connectors
Includes motherboard, CPU, PCIe, SATA and peripheral power connections for compatible desktop systems and storage devices.
Built-in Protection
Listed protection circuits include over-current, over-voltage, over-power, over-temperature, short-circuit and under-voltage protection.
Power Delivery and Cooling Technology
The Smart BX1 650W DC-to-DC version uses a single +12V rail rated at 54.1A, delivering up to 649.2W on that rail. This provides the primary power capacity for compatible CPUs and graphics cards, subject to the PSU's total rated output.
Active Power Factor Correction helps improve the relationship between input current and voltage. DC-to-DC conversion supports voltage regulation as the system's power demand changes.
The 120mm hydraulic bearing fan uses RPM control to provide cooling according to operating conditions. Thermaltake also lists a high-quality 105°C main capacitor for this version.
The PSU is 80 PLUS Bronze certified. Actual efficiency depends on operating load and input conditions, so certification should not be interpreted as a guaranteed percentage reduction in electricity consumption.

Before You Build
- Check the CPU and graphics-card manufacturers' recommended PSU wattage before selecting this 650W model.
- This is a non-modular PSU, so its cables are permanently attached. Plan cable routing and unused-cable storage accordingly.
- The listed GPU connectors are two PCIe 6+2-pin connectors. A native 12V-2x6 connector is not listed for this model.
- For graphics cards requiring a 16-pin power connection, use only a compatible, manufacturer-approved connection method and verify PSU capacity.
- Confirm the exact Smart BX1 version on the product label. Thermaltake sells multiple BX1 variants, and specifications can differ between versions.
Frequently Asked Questions
1. Is the Thermaltake Smart BX1 a 650W power supply?
Yes. This model is rated for 650W of total continuous output, with up to 649.2W available on the +12V rail.
