CORSAIR SF850 vs SAMA G850 Power Supply - 850W Fully Modular 80 Plus Gold Certified ATX 3.1 & PCI

Price Comparison

When comparing the prices of the CORSAIR SF850 and the SAMA G850 Power Supply, there's a significant difference. The CORSAIR SF850 is priced at £149.99, while the SAMA G850 is notably more affordable at £84.99. This represents a price difference of £65, making the SAMA G850 a more budget-friendly option. For users who are looking to save money without compromising too much on performance, the SAMA G850 offers a compelling choice. However, potential buyers should consider what features justify the higher cost of the CORSAIR SF850.

Efficiency Ratings

Efficiency is a critical factor when selecting a power supply, and in this regard, the two products differ. The CORSAIR SF850 boasts an impressive 80 PLUS Platinum rating, indicating superior energy efficiency and low power waste. In contrast, the SAMA G850 is rated at 80 PLUS Gold, achieving up to 91.15% efficiency at typical load. While both power supplies maintain high efficiency levels, the CORSAIR’s Platinum rating suggests it will perform slightly better, particularly in energy-intensive scenarios. This may lead to lower electricity bills over time, making it a more attractive proposition for users who value efficiency.

Modular Design

Both the CORSAIR SF850 and the SAMA G850 offer fully modular designs, allowing users to use only the cables they need. This feature enhances cable management and airflow within the case, fostering a neater build. The CORSAIR SF850 uses Type-5 Micro-Fit connectors, which are designed to take up less space, while the SAMA G850 features a native 12V-2x6 connector, specifically aimed at supporting NVIDIA GeForce RTX 50 and 40 Series GPUs. This flexibility means both units cater well to custom builds, but the specific connector types may influence compatibility with certain components.

Cooling Solutions

Cooling is essential for maintaining the longevity of components, and both power supplies have their unique cooling systems. The CORSAIR SF850 is equipped with a 92mm PWM cooling fan, designed for powerful yet low-noise operation thanks to its fluid dynamic bearing. Meanwhile, the SAMA G850 features a larger 140mm ECO fan with a similar fluid dynamic bearing, ensuring quieter operation and effective cooling. The larger fan in the SAMA G850 may provide better airflow, which could be beneficial for high-performance builds. However, users should keep in mind the specific cooling needs of their systems when selecting between these two options.

Build Quality and Components

The build quality of a power supply is paramount for reliability and performance. The CORSAIR SF850 employs 105°C rated Japanese capacitors, which are known for their durability and reliability under heavy loads. On the other hand, the SAMA G850 also utilises premium Japanese capacitors, ensuring stability and long life for its components. While both units incorporate high-quality materials, the specific temperature rating in the CORSAIR model may suggest a slight edge in handling extreme conditions, which could be a deciding factor for users who push their systems to the limit.

Compliance and Compatibility

Compliance with industry standards ensures that power supplies function safely and effectively with modern hardware. The CORSAIR SF850 is ATX 3.1 compliant and PCIe 5.1 ready, allowing it to support the latest platforms and graphics cards without issues. The SAMA G850 also meets the ATX 3.1 standard and includes a native 12V-2x6 connector for compatibility with NVIDIA's latest GPUs. This parity in compliance means both products are suitable for contemporary builds, but the added readiness of the CORSAIR for potential future upgrades may appeal to tech enthusiasts.

User Experience and Feedback

User experience can greatly influence the decision-making process when purchasing a power supply. The CORSAIR SF850 is often praised for its exceptional build quality and low noise levels, catering to users who prioritise a silent operation. Conversely, the SAMA G850 receives positive remarks for its value for money, particularly given its competitive pricing and solid performance metrics. Users looking for a cost-effective solution without sacrificing too much on performance may find the SAMA G850 to be a more attractive option, while those willing to invest more for premium features might lean towards the CORSAIR SF850.

Which should you buy?

In conclusion, the choice between the CORSAIR SF850 and the SAMA G850 Power Supply ultimately depends on your specific needs and budget. The CORSAIR SF850 offers superior efficiency with its 80 PLUS Platinum rating, robust build quality, and exceptional cooling capabilities, making it an ideal choice for high-performance builds. However, if you are looking for a more economical option that still delivers solid performance and essential features, the SAMA G850 at £84.99 presents an excellent value. Consider your priorities—whether it’s efficiency, cooling, or budget—before making a decision.
