Product identity

The Thermaltake Smart BM3 delivers 750 W through an ATX 3.0 compatible, semi-modular design. It includes a 120 mm FDB fan, active PFC and a 105°C Japanese main capacitor. The unit carries 80 PLUS Bronze certification at 115 Vac input and a full protection suite.

Who it suits

Builders moving to PCIe 5.0 graphics will appreciate the native 12+4pin connector rated for 300 W alongside four 6+2pin cables. The 150 mm depth fits most mid-tower cases, while semi-modular cabling keeps unused leads out of the airflow path. Systems needing fully modular cables or higher efficiency ratings should consider other models.

Build integration

A single 120 mm fan handles cooling, so case ventilation should allow rear exhaust. The compact 150 mm length frees space behind the motherboard tray for cable routing. DC-to-DC topology and a single high-amperage +12 V rail simplify GPU power distribution without extra adapters.

Perguntas sobre este artigo

What case clearance do I need for the 150 mm length?

The unit measures 150 mm deep so your case must provide at least that much clearance from the rear panel to any drive cage or motherboard tray.

Will the single 12+4pin connector feed a PCIe 5.0 graphics card while the four 6+2pin cables run older GPUs?

Yes, the native 12+4pin delivers up to 300 W for a Gen 5 card and the four 6+2pin connectors remain available for additional GPUs or peripherals.

How can I confirm the fan is operating correctly after installation?

The 120 mm FDB fan spins at startup; listen for smooth rotation and verify the PSU passes its 100-150 msec power-good signal and holds voltage for more than 17 msec during a brief power loss.
