Thermaltake introduced the Smart BM2 line of mainstream, semi-modular power supplies. Available in mid-range capacities of 450 W (model: PS-SPD-0450MNFABx-1), 550 W (PS-SPD-0550MNFABx-1), 650 W (PS-SPD-0650MNFABx), and 750 W (PS-SPD-0750MNFABx), these PSUs feature single +12 V rail designs with 80 Plus Bronze efficiency, DC-to-DC switching, APFC, Japanese main capacitors, and most common electrical protections, against over/under-voltage, overload, overheat, and short-circuit.

As semi-modular PSUs, the Smart BM2 comes with fixed 24-pin ATX, fixed 8-pin EPS, and an additional 4+4 pin EPS fixed connector, on all four models. The 450 W and 550 W models offer two 6+2 pin PCIe power connectors, while the 650 W and 750 W models offer four. The 450 W, 550 W, and 650 W models offer six SATA power connectors, while the 750 W model tops it up with nine. All models offer four Molex and a Berg. Black, flat cables are offered on all models, including for the fixed connectors. A 140 mm fan is used to cool the PSU, on all four models. Thermaltake is backing the Smart BM2 series with 5-year warranties. The company didn't reveal pricing.
