THERMALTAKE Smart BX3 750W 80+ Bronze ATX 3.1 Non Modular Power Supply

The Thermaltake Smart BX3 750W is a non-modular ATX power supply unit built to ATX 3.1 specifications, making it a solid choice for budget-conscious PC builders who need a reliable, modern foundation for their system. Certified to the 80 PLUS Bronze standard, it delivers efficiency levels reaching up to 85% under typical load conditions, helping to reduce energy waste and lower long-term running costs compared to uncertified units. At the heart of the Smart BX3's reliability is a high-quality 105°C-rated main capacitor, which enhances thermal tolerance and contributes to long-term stability. The unit features a high-amperage single +12V rail design paired with a DC-to-DC conversion circuit, which provides tighter voltage regulation and broad component compatibility — particularly beneficial for power-hungry CPUs and discrete graphics cards. Compliance with ATX 3.1 standards means the Smart BX3 750W supports up to 200% power excursion handling, meeting the transient power demands of modern GPUs. It also achieves 60% low-load efficiency and complies with ATX 3.1 power supply timing requirements, ensuring compatibility with current-generation platforms. The included 120mm fluid-bearing fan handles cooling duties, and the built-in Smart Zero Fan mode keeps the fan stationary at low loads — spinning only when the thermal threshold is reached — for a noticeably quieter desktop experience during light workloads. All cables use a flat black, non-modular design that eases routing within compact and mid-tower cases alike. The Smart BX3 750W is also Intel C6/C7 power state ready, ensuring deep sleep compatibility with Intel processors for maximum energy savings in idle scenarios. It ships with a 5-year manufacturer warranty, providing meaningful coverage for an entry-level unit. --- Verified Specifications --- Model Number: PS-SPD-0750NNFABD-3 Wattage: 750 W ATX Standard: ATX 3.1 Efficiency Certification: 80 PLUS Bronze Modularity: Non-modular Fan: 120mm fluid-bearing, Smart Zero Fan mode Main Capacitor Rating: 105°C PCIe Connectors (6+2 pin): 2 SATA Connectors: 4 Peripheral (4-pin Molex) Connectors: 4 Warranty: 5 Years Colour: Black
