SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC vs CORSAIR RM Series

Introduction to Power Supplies

When it comes to powering your PC, choosing the right power supply can make a significant difference in performance and reliability. In this comparison, we will look at the SAMA Black 850W Power Supply and the CORSAIR RM Series. Both products boast features designed to enhance your system's functionality, but they cater to different user needs and budgets.

Price Comparison

The SAMA Black 850W Power Supply is priced at a competitive C$89.99, making it an attractive choice for budget-conscious consumers. In contrast, the CORSAIR RM Series comes in at a higher price point of C$179.00. This difference of C$89.01 could influence your decision if you are looking for a cost-effective solution versus a premium offering. While the SAMA provides significant value for its price, the CORSAIR may justify its cost through additional features and brand reputation.

Design and Build Quality

The SAMA Black 850W Power Supply features a fully modular design, allowing users to connect only the cables needed for their specific builds. This streamlines cable management and improves airflow, which is essential for maintaining optimal cooling performance. On the other hand, the CORSAIR RM Series also adopts a fully modular approach, ensuring that users can avoid unnecessary clutter in their systems. Both power supplies are designed for modern builds, but the SAMA specifically highlights its flat cables for easier management, which could be a deciding factor for those prioritising aesthetics in their setups.

Cooling Solutions

Cooling capabilities are crucial for any power supply. The SAMA Black 850W is equipped with a 120mm ECO fan featuring Fluid Dynamic Bearing (FDB) technology, operating at noise levels as low as ≤20dB-A. This means it prioritises quiet operation, even under heavy loads. In comparison, the CORSAIR RM Series uses a 140mm rifle-bearing fan, designed to keep fan noise minimal, even at full load. Notably, it also includes a Zero RPM fan mode for silent operation during low to medium loads. Both power supplies offer effective cooling solutions, but the SAMA may have the edge in terms of ultra-quiet performance.

Efficiency Ratings

Efficiency is a critical consideration for power supplies, as it directly impacts energy consumption and system stability. The SAMA Black 850W boasts an 80 PLUS Gold certification, achieving up to 91.15% efficiency at 50% load. This level of efficiency minimizes energy waste and heat output, which can prolong component lifespan. In contrast, while the CORSAIR RM Series is also fully modular and aims for high performance, the specific efficiency rating isn't provided in the product data. However, the mention of industrial-grade, 105°C-rated capacitors suggests a focus on reliability and solid electrical performance.

Compatibility and Connection Options

When it comes to compatibility, the SAMA Black 850W supports the latest ATX 3.1 standards and comes with native PCIe 5.1 ports and cables. This makes it ideal for high-end GPUs like the RTX 3090 Ti and the RTX 40 series, ensuring peak performance for gamers and professionals alike. The CORSAIR RM Series, while not detailing specific GPU compatibility, mentions triple EPS12V connectors, which generally indicates good compatibility with modern graphics cards and motherboards. The emphasis on connection options in both models ensures users can build systems that meet their performance needs.

Warranty and Longevity

The SAMA Black 850W provides a 5-year warranty, reflecting the manufacturer's confidence in the product's longevity and reliability. This is a significant consideration for consumers looking for long-term investments in their PC builds. The CORSAIR RM Series does not explicitly mention a warranty period in the data provided, which might be a concern for some buyers. A robust warranty can offer peace of mind, especially for those investing in higher-end components.

Which should you buy?

Ultimately, the choice between the SAMA Black 850W Power Supply and the CORSAIR RM Series boils down to individual needs and budget considerations. The SAMA offers excellent value for money, with a lower price and strong efficiency ratings, making it a solid choice for budget builders. Conversely, the CORSAIR RM Series, while more expensive, may appeal to those prioritising brand reputation and premium features like the Zero RPM fan mode. Both power supplies are well-equipped for modern setups, but the best choice depends on your specific requirements and how much you’re willing to invest in your PC build.
