Sama K650 650W 80+ Bronze ATX 2.52 Non-Modular Power Supply (Black) (K0650-BKBFWA25-US)

This 650W power supply unit is designed to deliver reliable performance for standard desktop systems, featuring an ATX 2.52 form factor and a non-modular cable design. It comes in a compact 140 × 150 × 86 mm chassis with a clean black finish, making it suitable for most mid-tower builds. Certified with 80 PLUS Bronze efficiency, it achieves over 85% efficiency at typical (50%) load, helping reduce energy waste and heat output. With a mean time between failures (MTBF) of 100,000 hours, it is built for long-term stability.

Cooling is handled by a 120 mm sleeve-bearing fan, providing adequate airflow while maintaining relatively quiet operation. The unit supports a wide AC input range of 100–240V, ensuring compatibility across different regions. Internally, it utilizes an advanced topology combining APFC, Half-Bridge LLC, synchronous rectification (SR), and DC-DC conversion for stable and efficient power delivery. Multiple protection features are included—UVP, OVP, OCP, OPP, NLP, and SCP—safeguarding both the power supply and connected components. It operates within a temperature range of 0–40°C.
