Thermaltake Smart BM3 750W 80 PLUS Bronze Semi-Modular Power Supply
Thermaltake Smart BM3 750W 80 PLUS Bronze Semi-Modular Power Supply The Thermaltake Smart BM3 750W 80+ Bronze is a highly reliable, next-generation semi-modular power supply unit designed to deliver clean, efficient, and consistent power to modern gaming desktops, custom workstations, and daily computing setups. Fully built to comply with the latest ATX 3.0 standards and native PCIe 5.0 graphics interface requirements, this 750-watt power unit supplies a robust power foundation capable of handling real-time power excursions and high GPU power spikes from current and next-gen PC hardware. Featuring official 80 PLUS Bronze energy certification, the Smart BM3 750W guarantees up to 85% operational efficiency under typical real-world system loads. It incorporates a premium 105°C main Japanese electrolytic capacitor for enhanced electrical longevity and operational stability. Designed with a convenient semi-modular flat cable system, a powerful single +12V rail, and a silent 120mm Fluid Dynamic Bearing (FDB) cooling fan equipped with Smart Zero Fan technology, the Thermaltake Smart BM3 750W serves as an exceptional, future-proof power solution for modern PC builders. Native ATX 3.0 Standards & PCIe 5.0 12VHPWR Connector Ready Native 16-Pin Power Connector Built for Modern High-Performance Graphics Cards As high-performance graphics processing units require greater power capacity during demanding gaming scenes and rendering tasks, meeting updated hardware specifications is essential. The Thermaltake Smart BM3 750W is designed to comply fully with ATX 3.0 guidelines, supporting up to 200% total power excursion headroom and delivering rapid power response times without system interruption or unexpected power cutoffs. Outfitted with a native 16-pin 12VHPWR (12+4 pin) PCIe 5.0 power connector, this unit delivers up to 450W of continuous power directly to high-draw graphics cards using a single clean cable. This eliminates the need for legacy adapter cables, reducing clutter inside the case and ensuring stable current distribution. 80 PLUS Bronze Energy Efficiency & Main Japanese 105°C Capacitor High Electrical Conversion Rate with Extended Component Durability and Low Heat Output Certified under the official 80 PLUS Bronze energy standard, the Smart BM3 750W achieves up to 85% energy conversion efficiency under normal operating loads (20% to 100% capacity). Efficient power conversion ensures that less electricity drawn from the wall outlet is converted into waste heat, keeping internal chassis temperatures down and reducing overall power consumption. Furthermore, the unit features a high-grade primary Japanese main capacitor rated for operation up to 105°C (221°F). This premium component ensures reliable power output, high heat resistance, and long-term durability even under sustained heavy-load computing sessions. 120mm FDB Fan with Smart Zero Fan Silent Operation Mode Whisper-Quiet 0dB Acoustic Performance paired with Intelligent Internal Cooling To maintain low operational noise without compromising component cooling, the Smart BM3 750W utilizes a 120mm Fluid Dynamic Bearing (FDB) fan. Known for its low friction, reduced vibration, and long service life, the FDB fan delivers steady airflow across internal heatsinks and power rails during heavy processing tasks. Integrated with a physical Smart Zero Fan switch on the rear panel, users can activate a dead-silent 0dB operational mode. When enabled, the cooling fan remains completely stationary when total power loads are under 20%, allowing for silent, distraction-free performance during light desktop tasks like browsing, typing, or listening to music. Semi-Modular Flat Cable Design & Full Industrial Protection Suite Streamlined Cable Routing, Improved Internal Airflow, and Comprehensive Circuit Defense The semi-modular cable setup keeps essential system power lines attached (24-pin ATX and CPU EPS) while offering flexible, detachable modular flat black cables for peripheral connections and graphics expansion cards. This design simplifies cable management, eliminates unused cable clutter behind motherboard trays, and ensures unobstructed airflow through your desktop chassis. To safeguard your valuable computer components against unforeseen power hazards, the Smart BM3 750W includes a full suite of industrial-grade electrical protections: Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Over Current Protection (OCP), and Over Temperature Protection (OTP).
