650 W ATX 3.0 power supply

The Thermaltake Smart BM3 delivers 650 W of continuous power for modern desktop builds. It meets the Intel ATX 3.0 standard and carries 80 PLUS Bronze certification at 115 V input. A 120 mm FDB fan and a 105°C Japanese main capacitor support reliable operation.

Native 12+4 pin PCIe 5.0 connector

A single 12VHPWR connector rated for 300 W plugs directly into current-generation graphics cards without an adapter. Four additional 6+2 pin PCIe connectors remain available for other expansion cards or accessories.

Semi-modular cabling in a 150 mm chassis

Fixed 24-pin ATX and EPS cables simplify the core install while peripheral cables attach only as needed. The 150 mm depth fits most mid-tower cases and leaves room for cable routing behind the motherboard tray.
