THERMALTAKE Smart BX1 550W 80 Plus Bronze Non Modular ATX 2.0 Power Supply ( 550W ) ( DC To DC Version )

The Thermaltake Smart BX1 550W is a non-modular ATX 2.0 power supply designed for value-oriented PC builders who need dependable, efficient power delivery without compromise. Carrying the 80 PLUS Bronze certification, this unit meets the 80 PLUS Bronze efficiency standard at 115 Vac input, helping reduce wasted energy and lower heat output inside your case. At the heart of the cooling system sits a 120mm hydraulic bearing fan with intelligent RPM control. The fan adjusts its speed in response to internal temperatures, keeping the PSU quiet during light loads while ramping up only when thermal conditions demand it. The result is a power supply that operates unobtrusively in everyday desktop and gaming workloads. The Smart BX1 550W uses a DC-to-DC circuit design to derive the minor rails from the primary +12V rail. This topology improves voltage regulation and load stability compared to traditional group-regulated designs, making it a sound choice for modern processors and graphics cards that draw fluctuating current. The single high-amperage +12V rail supports a wide range of system configurations. Six layers of hardware protection are built in: Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP). These safeguards are designed to shut the unit down safely before damage can reach connected components. The black, low-profile cable set helps with routing in compact and mid-tower cases, reducing obstruction to chassis airflow. Two PCI-E 6+2 pin connectors are included, supporting single-GPU builds. Thermaltake backs the Smart BX1 550W with a 5-year warranty and the unit carries multiple safety certifications including CE, UKCA, LVD, FCC, ICES, TUV, CB, cTUVus, and BSMI.
