Price Comparison

When it comes to pricing, the SAMA Black 850W Power Supply is significantly more affordable, retailing at C$89.99, compared to the CORSAIR RM850e, which is priced at C$184.99. This substantial difference of C$95 highlights the SAMA as a budget-friendly option for those looking to build a gaming rig or workstation without breaking the bank. However, while price is a crucial factor, it’s essential to consider the features and performance each unit offers to ensure you get the best value for your money.

Build Quality and Design

Both power supplies feature a fully modular design, allowing you to connect only the necessary cables for your build. The CORSAIR RM850e boasts reliable and efficient performance with its low-noise operation. Its design is complemented by a 120mm rifle bearing fan, which operates quietly even under full load. On the other hand, the SAMA Black 850W Power Supply employs flat cables that enhance cable management, improving airflow within the case. Users seeking a clean aesthetic may prefer the streamlined look of the SAMA, while those prioritising noise reduction might lean toward the CORSAIR.

Certification and Efficiency

The efficiency ratings of both power supplies are noteworthy, with the SAMA Black featuring dual Gold certifications, including 80 PLUS Gold and CYBENETICS Gold. This indicates that it can achieve up to 91.15% efficiency at 50% load, thereby reducing energy waste and heat output. In contrast, while the CORSAIR RM850e is Intel ATX 3.1 certified, specific efficiency ratings are not provided in the data. However, its 105°C-rated capacitors assure users of steady power delivery and dependable performance, making both units reliable choices in terms of efficiency.

Compatibility Features

Compatibility is crucial for any power supply, especially for high-performance builds. The CORSAIR RM850e supports the latest ATX 3.1 power standard and PCIe 5.1 platforms, which are crucial for modern graphics cards. It can withstand transient power excursions from GPUs, making it an excellent choice for gamers and professionals alike. The SAMA Black also meets ATX 3.1 standards and comes equipped with native PCIe 5.1 ports, ensuring seamless compatibility with high-end GPUs like the RTX 3090 Ti and the RTX 40 series. Both products excel in this category, making them suitable for cutting-edge builds.

Cooling Solutions

Cooling is vital for maintaining performance and longevity in power supplies. The CORSAIR RM850e utilises a 120mm rifle bearing fan designed to minimise noise, ensuring quiet operation even under full load. In comparison, the SAMA Black incorporates a 120mm ECO fan with Fluid Dynamic Bearing (FDB) technology, which operates at noise levels as low as ≤20dB-A, providing an exceptionally quiet experience. Both units are designed to keep temperatures down, though the SAMA's cooling technology may offer a slight edge in terms of noise reduction, which is an important factor for many users.

Component Longevity and Warranty

The longevity of a power supply can often be gauged by the quality of its components and the warranty offered. The CORSAIR RM850e features 105°C-rated capacitors, ensuring reliable power and performance over time. However, the SAMA Black not only uses premium Japanese capacitors for stable power delivery but also comes with a 5-year warranty, providing added peace of mind for users concerned about long-term reliability. While both brands are reputable, the extended warranty on the SAMA may appeal to those looking for extra assurance on their investment.

User Experience and Noise Levels

User experience is a critical aspect when selecting a power supply, and both the CORSAIR RM850e and the SAMA Black excel in delivering a positive experience. The CORSAIR is known for its low-noise operation, thanks to its specially calculated fan curve, which keeps noise levels down even during high loads. Conversely, the SAMA Black's ECO fan technology ensures that noise levels remain exceptionally low, making it ideal for quiet builds. Users who prioritise a silent operation may find the SAMA more appealing, while those who appreciate the proven reputation of Corsair might prefer the RM850e.

Which should you buy?

Choosing between the CORSAIR RM850e and the SAMA Black 850W Power Supply ultimately depends on your specific needs and budget. If you're looking for a high-quality, reliable unit and are willing to invest more, the CORSAIR RM850e offers exceptional build quality, low noise levels, and robust performance. Conversely, if budget is your primary concern and you still desire a power supply with great features and efficiency, the SAMA Black is a compelling option at a significantly lower price point. Consider your priorities in terms of performance, noise levels, and warranty to make the best choice for your system.
