Thermaltake Smart BX1 550 Watt 80 Plus Bronze SMPS

The Thermaltake Smart BX1 550W is a value-oriented ATX power supply designed for mainstream desktop builds that demand stable, efficient power delivery without unnecessary complexity. Certified to the 80 PLUS Bronze standard, the unit achieves up to 88% energy efficiency at 115Vac input, helping to reduce heat output and lower running costs compared to uncertified alternatives. At the heart of the Smart BX1's cooling solution is a 120mm hydraulic bearing fan with intelligent RPM controls. The hydraulic bearing design extends operational lifespan and keeps noise levels low under typical workloads, making the unit suitable for home offices and study environments. Japanese main capacitors are specified in the source data, contributing to consistent voltage regulation across the unit's rated operating life. The power supply features a high-amperage single +12V rail, which is the primary power path for modern CPUs and discrete graphics cards. This design avoids the current-sharing complexity of multi-rail designs and simplifies compatibility across a broad range of components. Ripple noise is kept below 80mV on the +12V rail and below 40mV on the +5V and +3.3V rails across the full 0–100% load range, meeting common requirements for graphics cards and storage devices. Cabling uses sleeved black soft cables, easing installation in mid-tower and smaller ATX cases. The connector set includes two PCIe 6+2-pin connectors for graphics cards, six SATA connectors, and four 4-pin peripheral connectors, alongside the standard 24-pin ATX and CPU power headers. The ATX 12V v2.3 and EPS v2.92 compliance means it is compatible with a wide range of Intel and AMD platforms. Safety certifications include CE, CB, TUV, UL, FCC, and BSMI, and the unit carries Active PFC for compliance with international power-quality standards. Thermaltake backs the Smart BX1 with a 5-year warranty.
