Gigabyte P750BS 80 Plus Bronze Non Modular 750w Power Supply Unit vs SAMA G850 Power Supply - 850W Fully Modular 80 Plus Gold Certified ATX 3.1 & PCI

Price Comparison

The Gigabyte P750BS is priced at £57.55, while the SAMA G850 costs £84.99. This significant price difference of £27.44 indicates that the Gigabyte model is a more budget-friendly option for users seeking a reliable power supply. While the SAMA offers higher wattage and additional features, the Gigabyte provides solid performance at a lower cost, making it an attractive choice for those on a tighter budget. When evaluating price alone, the Gigabyte P750BS stands out as the more economical option without sacrificing essential functionality.

Efficiency Ratings

The SAMA G850 boasts an impressive 80 Plus Gold certification, achieving up to 91.15% efficiency at typical loads. In contrast, the Gigabyte P750BS is 80 Plus Bronze certified, which indicates it operates with slightly lower efficiency. This difference in efficiency ratings signifies that the SAMA G850 is designed to waste less power and generate less heat, which is crucial for energy-conscious users. For those prioritising performance and energy savings, the SAMA G850 is the superior choice based on its higher efficiency standard.

Modular Design

One of the standout features of the SAMA G850 is its fully modular cable design, which allows users to connect only the cables they need. This not only enhances airflow but also improves cable management and overall aesthetics in high-end builds. The Gigabyte P750BS, on the other hand, is non-modular, meaning all cables are permanently attached. This can result in a cluttered interior and may complicate upgrades or maintenance. If a clean and organised build is a priority, the SAMA G850’s modularity makes it the better option.

Cooling Systems

The SAMA G850 features a silent 140mm Fluid Dynamic Bearing (FDB) fan, designed to provide efficient cooling while minimising noise. This is a significant advantage for users who demand a quiet computing environment. The Gigabyte P750BS, while equipped with a 120mm Silent FDB fan, may not perform as effectively in terms of cooling due to its smaller size. Users looking for superior thermal management should consider the SAMA G850, as its larger fan can contribute to better airflow and quieter operation.

Protection Features

Both power supplies come equipped with multiple protection features to ensure safe operation. The SAMA G850 includes OVP, OCP, OTP, OPP, SCP, UVP, and SIP protections, which provide a comprehensive safety net against various electrical issues. The Gigabyte P750BS also offers OVP, OPP, SCP, UVP, OCP, and OTP protection, though the SAMA’s inclusion of SIP (Surge Impact Protection) adds an extra layer of safety. For users prioritising comprehensive protection, the SAMA G850 is the more robust choice.

Compatibility with New Technologies

The SAMA G850 is compliant with the latest ATX 3.1 standard and features a native 12V-2x6 connector specifically for NVIDIA GeForce RTX 50 and 40 Series GPUs. This positions it as a forward-thinking option for gamers and professionals using high-performance graphics cards. The Gigabyte P750BS does not mention compatibility with such advanced standards or connectors. If future-proofing is a key consideration, particularly for users planning on high-end builds, the SAMA G850 is clearly the superior choice.

Build Quality and Components

The SAMA G850 is constructed with premium Japanese capacitors, ensuring long life and stability, which is essential for maintaining consistent performance over time. The Gigabyte P750BS, while designed for durability, does not specify the type of components used. Users who are keen on longevity and reliability in their power supply could lean towards the SAMA G850 due to its high-quality components, which may lead to enhanced performance and reduced failure rates.

Which should you buy?

Choosing between the Gigabyte P750BS and the SAMA G850 ultimately depends on your specific needs and budget. If you are looking for a cost-effective solution that delivers reliable performance, the Gigabyte P750BS at £57.55 is a solid choice. However, for those who seek higher efficiency, modularity, and advanced features, the SAMA G850, priced at £84.99, offers superior performance and future-proofing capabilities. Therefore, for users prioritising quality and features over price, the SAMA G850 emerges as the clear winner.
