Smart BX1 750W at a Glance
Introduction
The Thermaltake Smart BX1 750W 80 PLUS Bronze Power Supply (PS-SPD-0750NNFABD-4) is designed for desktop systems that need dependable power for everyday computing, productivity and compatible gaming configurations. Its 750W rated output provides a practical power foundation for a range of component combinations.
This DC-to-DC version combines active power factor correction with DC-to-DC conversion to support stable power delivery across the output rails. Its 80 PLUS Bronze certification indicates that the unit meets defined efficiency requirements at the specified test input conditions.
A 120mm hydraulic-bearing fan provides active cooling, while the non-modular cable design keeps all power leads permanently attached. The compact 140mm-deep chassis fits many standard ATX-compatible cases, subject to available clearance and cable-routing space.
With a five-year manufacturer warranty and multiple built-in protection mechanisms, the Smart BX1 is a practical option for budget-conscious PC builds that do not require a modular PSU or a native 16-pin GPU power connection.
Key Features
750W Continuous Power
Provides a rated 750W output for compatible desktop systems. The available power must be matched to the combined requirements of the processor, graphics card and other components.
80 PLUS Bronze Efficiency
Bronze certification confirms compliance with defined power-conversion efficiency requirements at specified test conditions, helping limit wasted energy and heat.
DC-to-DC Conversion
The DC-to-DC design supports regulation of the secondary voltage rails, helping maintain stable power delivery as component loads change.
120mm Hydraulic-Bearing Fan
A 120mm hydraulic-bearing fan helps dissipate heat during operation. Actual fan noise and speed depend on operating temperature and system load.
Multiple Protection Circuits
Listed protections include over-current, over-voltage, over-power, over-temperature, short-circuit and under-voltage protection.
Compact ATX Chassis
The 140mm chassis depth supports installation in many ATX-compatible cases, while its non-modular cables require planning for unused leads.
Power Delivery and Protection Technology
The Smart BX1 750W uses active power factor correction and DC-to-DC conversion. Active PFC helps improve the relationship between the PSU's input voltage and current, while DC-to-DC conversion supports the regulation of secondary output rails.
The unit accepts a universal 100–240V AC input range and is rated for 750W of total output. The +12V rail is rated at 56A, equivalent to 672W, making it the primary source of power for the CPU and graphics card.
Protection circuits include OCP, OVP, OPP, OTP, SCP and UVP. These are designed to respond to specified abnormal electrical or thermal conditions; they do not replace suitable system design, correct installation or a stable mains supply.
Technical Specifications
Connector quantities and cable arrangements can vary across product revisions and regional listings. Verify the physical cable set for the exact SKU before publication or purchase. This model is not advertised as ATX 3.1 and does not list a native 12V-2x6 connector.
Ideal Use Cases
Mainstream Gaming PCs
Suitable for compatible gaming systems whose combined component power demand fits within the PSU's 750W rating and available PCIe connectors.
Home and Office Desktops
Provides power for everyday computing, office applications and general desktop workloads in a compatible system.
Productivity Builds
A practical option for suitable development, multitasking and content-creation PCs that do not require a higher power class or native 16-pin GPU cable.
Budget-Conscious Builds
The non-modular design and Bronze certification make it an option for users prioritising basic functionality and cost over detachable cables and premium efficiency.
Before You Build
- Check the recommended PSU wattage for your exact CPU and graphics card before purchasing.
- This model lists two PCIe 6+2-pin connectors. Confirm that your graphics card's power input can be supplied correctly without exceeding cable or PSU ratings.
- The Smart BX1 is non-modular, so all cables remain attached. Plan cable management and check the space available behind the motherboard tray.
- Do not assume this model supports ATX 3.1, PCIe 5.1 or a native 12V-2x6 connection; those features are not established for this SKU.
- For graphics cards requiring a 16-pin power connector, choose a PSU with the appropriate native connector or use only a connection method explicitly approved by the GPU manufacturer.
Frequently Asked Questions
1. What is the Thermaltake Smart BX1 750W?
It is a 750W ATX power supply with 80 PLUS Bronze certification, active PFC, DC-to-DC conversion and a 120mm hydraulic-bearing fan. The exact SKU is PS-SPD-0750NNFABD-4.
2. Is the Smart BX1 750W modular?
No. It is a non-modular PSU, meaning its power cables are permanently attached. Unused cables need to be managed inside the case.
3. What does 80 PLUS Bronze mean?
It indicates that the PSU meets specified power-conversion efficiency requirements under defined test conditions. Actual efficiency depends on the operating load and input conditions.
4. Does this PSU use DC-to-DC conversion?
Yes. This specific Smart BX1 version is identified as the DC-to-DC model, which uses DC-to-DC conversion to regulate secondary output rails.
5. How many PCIe GPU power connectors does it have?
The matching Indian listing specifies two PCIe 6+2-pin connectors. Check your graphics card's connector requirements before buying, especially for higher-power GPUs.
6. Is it compatible with modern 16-pin graphics cards?
A native 12V-2x6 connector is not listed for this model. A graphics card requiring a 16-pin connector needs a suitable, manufacturer-approved connection solution and adequate power capacity.
7. What are the dimensions of the Smart BX1 750W?
The listed dimensions are 150mm wide, 86mm high and 140mm deep. Check the PSU clearance and cable-routing space in your cabinet before installation.
8. What warranty does this PSU include?
The matching Indian product listing specifies a five-year warranty, subject to the manufacturer's applicable warranty terms and conditions.
