Price Comparison

The SAMA G850 Power Supply is priced at £84.99, significantly higher than the Tecnoware Power Systems Free Silent PRO 650, which retails for just £32.90. This price difference of £52.09 reflects the varying power capacities and features of these two products. The SAMA G850 offers 850W of power, making it suitable for high-performance systems, while the Tecnoware Free Silent PRO 650 provides 650W, catering to mid-range setups. This disparity in price and power output is essential for consumers to consider, particularly when assessing their specific needs for a power supply.

Power Output and Efficiency

The SAMA G850 boasts an impressive 850W output, ideal for demanding gaming setups and workstations. It is certified with an 80 Plus Gold efficiency rating, achieving up to 91.15% efficiency at typical loads. In contrast, the Tecnoware Free Silent PRO 650 provides 650W, which is adequate for less demanding systems using mid-range graphics cards. While the Tecnoware does not specify an efficiency rating, it is designed for stability and efficiency in systems with components such as the GTX 1660 Ti and RTX 3050. The higher wattage of the SAMA G850 allows for more headroom in power delivery, making it a better choice for users with higher performance demands.

Modular Design

The SAMA G850 features a fully modular cable design, allowing users to connect only the cables they need. This design promotes better airflow and cable management, making for cleaner builds and improved aesthetics. In comparison, the Tecnoware Free Silent PRO 650 does not mention a modular design, which may lead to more cluttered setups and potentially hinder airflow. The SAMA's fully modular approach is particularly advantageous for users who prioritise a neat and efficient installation, which is valuable for both practical and aesthetic reasons.

Cooling Solutions

Cooling is a crucial aspect of power supplies, and the SAMA G850 is equipped with a 140mm Fluid Dynamic Bearing (FDB) fan designed to operate quietly while maintaining effective cooling. This feature is complemented by the use of premium Japanese capacitors, ensuring long life and stability. On the other hand, the Tecnoware Free Silent PRO 650 utilises a 12 cm ultra-silent fan with automatic speed adjustment. While both power supplies focus on quiet operation, the larger fan in the SAMA G850 may provide superior cooling performance due to its size and design. This aspect is particularly relevant for users who plan to push their systems to higher performance levels.

Connector Compatibility

In terms of connector options, the SAMA G850 is specifically tailored for the latest graphics cards, including NVIDIA's RTX 50 and 40 Series, featuring a native 12V-2x6 connector. This ensures compatibility with modern, high-performance components. The Tecnoware Free Silent PRO 650, while also supporting a range of graphics cards, provides a different set of connectors, including a 20+4 pin and various SATA connectors. However, for users looking to future-proof their builds or utilise the latest technology, the SAMA G850 offers a more robust solution. The focus on advanced compatibility in the SAMA unit may be a deciding factor for gamers and professionals alike.

Size and Form Factor

The SAMA G850 is compact, measuring 150mm x 150mm x 86mm, making it suitable for a variety of cases without compromising space. The Tecnoware Free Silent PRO 650 has similar dimensions at 14 cm x 15 cm x 8.6 cm. However, the slight differences in dimensions may influence compatibility with specific cases, especially in tighter builds. Users should consider their case dimensions and layout when selecting a power supply, as both units are designed to fit in standard ATX cases.

Safety Features

Safety is paramount in power supply design, and both the SAMA G850 and the Tecnoware Free Silent PRO 650 come equipped with multiple protection features. The SAMA G850 includes protections against overvoltage, overload, short circuits, and more, ensuring a safe operation across varying conditions. Similarly, the Tecnoware unit offers protection systems against power surges, overloads, and short circuits, which are critical for maintaining reliability. While both models prioritise safety, the extensive range of protections in the SAMA G850 may provide added peace of mind for users pushing their systems to the limit.

Which should you buy?

Choosing between the SAMA G850 Power Supply and the Tecnoware Free Silent PRO 650 largely depends on your specific needs and budget. The SAMA G850, with its higher wattage, fully modular design, superior cooling capabilities, and compatibility with the latest graphics cards, is ideal for high-performance gaming and workstation setups. However, it comes at a higher price point of £84.99. In contrast, the Tecnoware Free Silent PRO 650 offers a more budget-friendly option at £32.90, suitable for mid-range systems but with less power and fewer advanced features. Ultimately, if you require a power supply that can support demanding components and provide efficient cooling, the SAMA G850 is the better choice. Conversely, for users with more modest requirements, the Tecnoware Free Silent PRO 650 presents a reliable and economical solution.
