Description

Power up Next-Gen Hardware.
The semi-modular Smart BM3 power supply with 80 PLUS Bronze certification (550W/650W/750W/850W) is designed to meet ATX 3.0 standards. It also features a PCIe Gen 5.0 (12VHPWR) connector to support modern graphics cards. With a generous 5-year warranty, the Smart BM3 series is poised to satisfy the market where value-oriented users are seeking a new power supply with all the latest features.

Fully compatible with Intel ATX 3.0 standards

The Smart BM3 series is fully compliant with Intel ATX 3.0 specifications, supporting up to 200% power output, achieving 60% efficiency at low load, and meeting the required power supply timing standards.

Ready for PCIe Gen 5.0

The Smart BM3 Bronze series features a 16-pin connector to deliver powerful and stable performance, enabling the power supply to natively support next-generation GPUs.
The power listed on the 12VHPWR connector is the recommended power.
The 16-pin PCIe (12VHPWR) connector of the Smart BM3 850W can deliver up to 450W for PCIe 5.0 graphics cards.

Built to meet the latest graphics cards

As the power consumption of graphics cards increases, so does their power demand. The Smart BM3 series is designed to support NVIDIA and AMD graphics cards, supports 8-pin PCIe cables for AMD graphics cards & entry-level RTX 40 series graphics cards, and also features a 1 x 16-pin connector for RTX 40 series cards that require a PCIe Gen 5.0 connector, ready to power the graphics cards according to their different connection methods.

Stay smart, stay quiet

It features a 120mm FDB fan for excellent airflow. Additionally, with the Smart Zero Fan function, the fan will not spin until the load exceeds 20% of the power supply load, minimizing unwanted noise.

High-quality Japanese electrolytic capacitor 105°C/221°F Main Electrolytic Capacitor

The high-quality Japanese main electrolytic capacitor significantly improves the durability of the power supplies and ensures the stability and reliability of the Smart BM3 series.

High current design on a single +12V rail and DC to DC

The powerful single +12V rail can properly provide the power you need for better compatibility. The use of LLC circuit design and DC to DC ensures very stable operation and improved voltage regulation.

Industrial-grade integrated protection

For hardware protection, the Smart BM3 is built with industrial-grade protection: OCP (Over Current Protection), OVP (Over Voltage Protection), UVP (Under Voltage Protection), OPP (Over Power Protection), SCP (Short Circuit Protection), OTP (Over Temperature Protection).

Semi Modular Flat Cable Design

The soft black flat cables come with cable sleeving, designed to make cable installation an easy task, while fully powering the system at optimal voltages.

80 Plus Bronze Certification

Saves energy through high energy efficiency up to 85%. It has been optimized to work with all generations of Intel processors to achieve maximum energy savings.

    Excellent power supply, high quality, compact and functional with a completely silent fan.
    I believe you don't need to spend more money if you are an average user with a PC in the range of 1000-1500 euros. I have a small case and cable management was effortless.
    Bonus points for the total black flexible cables.
