ATX 3.0 and PCIe 5.0 (12VHPWR) support

Ready for the latest graphics cards. The dedicated 12VHPWR connector delivers stable power without adapters and unnecessary heat buildup.

Quiet operation with Smart Zero Fan

Smart fan control switches the fan off at low load. The result is quieter, more efficient operation without compromise.

80 PLUS Bronze efficiency and DC-DC stability

Efficient power delivery with lower losses and stable voltage rails thanks to a modern DC-DC design for demanding builds.

The Thermaltake Smart BM3 850W is an ideal choice for gaming PCs and high-performance workstations. With 80 PLUS Bronze efficiency, it saves energy and ensures stable power even under heavy load. Modular cabling simplifies cable management and improves case airflow.

The modern ATX 3.0 standard and support for PCIe 5.0 / 12VHPWR allow you to power the latest graphics cards. Smart Zero Fan technology minimizes noise—the fan spins up only at higher temperatures or loads. The DC-DC topology delivers stable voltage rails and greater system reliability.
