THERMALTAKE SMART BX1 SERIES
Thermaltake Smart BX1 550W 80 PLUS Bronze Power Supply
Reliable 550W power with DC-to-DC conversion, Bronze-rated efficiency, active PFC and a hydraulic-bearing cooling fan for compatible desktop and mainstream gaming PCs.
Smart BX1 550W at a Glance
Introduction
The Thermaltake Smart BX1 550W 80 PLUS Bronze Power Supply (PS-SPD-0550NNFABD-4) is designed for budget-conscious desktop builds that need dependable power delivery without unnecessary complexity. Its 550W rated output makes it a potential fit for office PCs, everyday computing systems and compatible mainstream gaming configurations.
The DC-to-DC design helps regulate the secondary output rails under varying system loads. Active power factor correction (PFC) supports efficient use of incoming AC power, while 80 PLUS Bronze certification verifies that the PSU meets defined efficiency requirements.
A 120mm hydraulic-bearing fan provides cooling, and the non-modular cabling keeps the design straightforward. Two PCIe 6+2-pin connectors support compatible graphics cards, subject to the GPU's power requirements.
With a standard ATX form factor and a listed five-year warranty, the Smart BX1 550W is worth considering for a compatible value-focused PC build.
Key Features
550W Power Output
Provides 550W of rated power for compatible desktops and mainstream PC configurations with appropriately sized components.
80 PLUS Bronze Efficiency
Bronze certification indicates that the PSU meets defined AC-to-DC conversion-efficiency requirements under specified test conditions.
DC-to-DC Conversion
The DC-to-DC design supports regulation of the secondary voltage rails as system demands change, helping maintain stable power delivery.
120mm Hydraulic-Bearing Fan
A hydraulic-bearing fan provides airflow for cooling the PSU during operation. Fan speed and noise depend on load and temperature.
Six Protection Mechanisms
Listed protections include over-current, over-voltage, over-power, over-temperature, short-circuit and under-voltage protection.
Essential PC Connectors
Includes two PCIe 6+2-pin connectors for compatible graphics cards, alongside the power connections needed for a standard desktop build.
Power Delivery and Cooling Technology
The Smart BX1 uses a DC-to-DC design intended to improve secondary-rail regulation as the system's load changes. Combined with active PFC, this provides a practical power-delivery platform for compatible everyday desktop and gaming systems.
Its 80 PLUS Bronze certification indicates compliance with defined efficiency thresholds at specified test loads and input conditions. Actual efficiency depends on the system load and AC input; the certification does not guarantee a fixed reduction in electricity costs.
A 120mm hydraulic-bearing fan cools the internal components. The PSU also lists six protection mechanisms intended to help protect the power supply and connected components against specified electrical or thermal fault conditions.

Before You Build
- Check the recommended PSU wattage for your exact CPU and graphics card before purchase.
- This is a non-modular power supply. Its cables are permanently attached, so allow sufficient space for unused cables inside the case.
- The listed GPU power connections are two PCIe 6+2-pin connectors. This model should not be assumed to include a native 12V-2x6 connector.
- Confirm the exact SATA and peripheral connector count with the seller or the manufacturer's documentation for this SKU.
- For higher-power graphics cards, significant overclocking or future upgrades, check transient power demands and consider a higher-capacity PSU with the required native connectors.
Frequently Asked Questions
1. What is the rated output of the Thermaltake Smart BX1?
This model is rated for 550W. Whether it is sufficient depends on the complete system's power demand and the component manufacturers' recommendations.
2. Is the Smart BX1 550W 80 PLUS Bronze certified?
Yes. The Smart BX1 550W carries 80 PLUS Bronze certification. Actual efficiency varies with load and input conditions.
