THERMALTAKE Smart BX1 550 Watt 80 Plus Bronze SMPS PSU

The Thermaltake Smart BX1 550W is a non-modular ATX power supply built for value-focused PC builders who need dependable, efficient power delivery. Certified 80 PLUS Bronze at 115 Vac input, it meets the efficiency threshold that reduces wasted energy and lowers heat output inside your chassis. The unit delivers its full 550 W rated capacity at operating temperatures up to 40°C, making it suitable for mid-range gaming and productivity rigs alike. At the heart of the cooling solution is a 120 mm hydraulic bearing fan with intelligent RPM controls. This bearing type is known for quiet operation and extended service life, keeping acoustics low during everyday tasks while ramping up only when thermals demand it. The power supply uses Japanese main capacitors for voltage stability, and its single +12V rail design simplifies power delivery to demanding components such as discrete graphics cards. Two PCI-E 6+2-pin connectors are included, supporting a broad range of modern GPUs. Ripple noise is kept tightly in check — below 80 mV on the +12V rail and below 40 mV on the +5V and +3.3V rails across the full load range — helping sensitive components operate reliably over time. Active PFC ensures a high power factor across the supported universal input voltage range of 100 V to 240 V, making the unit compatible with Indian mains as well as international outlets. Safety certifications include CE, CB, TUV, UL, FCC, and BSMI, covering major global markets. Thermaltake backs the Smart BX1 550W with a 5-year warranty and lists a minimum MTBF of 100,000 hours.
