SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC vs CORSAIR CX750M

Price Comparison

The SAMA Black 850W Power Supply is priced at C$89.99, while the CORSAIR CX750M costs C$124.99. This makes the SAMA a more budget-friendly option, with a significant price difference of C$35.00. For users looking to save money without compromising on quality, the SAMA provides an attractive entry point into high-efficiency power supplies. However, the higher price of the CORSAIR may reflect additional features or perceived brand value that some users may find worth the extra cost.

Power Output

The SAMA Black offers an impressive 850W of power, making it suitable for high-performance gaming rigs and demanding workstations. In contrast, the CORSAIR CX750M provides 750W of power. While both power supplies support the latest standards, the SAMA's higher wattage allows for more headroom when using power-hungry components, such as the latest GPUs. This makes the SAMA a better choice for users planning to install multiple high-end components in their builds.

Modular Design

Both power supplies feature modular designs, but they differ in their configurations. The SAMA Black offers a fully modular design, allowing users to connect only the cables needed for their specific setup. This can greatly improve cable management and airflow within a PC case. The CORSAIR CX750M, on the other hand, is semi-modular, meaning that while some cables are detachable, the main power cables are permanently attached. This could result in more clutter in cases where not all of the attached cables are necessary, potentially hindering airflow.

Compatibility with Modern Standards

Both power supplies are designed to meet the latest ATX 3.1 and PCIe 5.1 standards, ensuring compatibility with the newest graphics cards, including Nvidia's RTX 40 and 50 series. This feature is crucial for gamers and professionals who want to future-proof their systems. The SAMA Black explicitly states its support for high-end GPUs like the RTX 3090 Ti and RTX 40 series, while the CORSAIR CX750M also assures compatibility with the newest Nvidia GPUs without needing adapters. Users can confidently build their systems knowing that both options will support the modern components they wish to use.

Cooling Solutions

Cooling is vital for maintaining system stability and performance. The SAMA Black is equipped with a 120mm ECO fan that utilises Fluid Dynamic Bearing (FDB) technology, which operates at noise levels as low as 20dB-A. This ensures quiet operation even under heavy loads. In contrast, the CORSAIR CX750M also features a 120mm low-noise fan that runs silently under low and medium loads. While both power supplies prioritise quiet operation, the SAMA's lower noise rating may appeal to users who are particularly sensitive to sound, especially in quiet environments.

Efficiency Ratings

Efficiency is a critical factor in power supply performance, and both units boast high efficiency ratings. The SAMA Black has achieved an 80 PLUS Gold certification, indicating that it can reach up to 91.15% efficiency at 50% load. This not only reduces energy waste but also enhances system stability while prolonging the lifespan of components. The CORSAIR CX750M is also rated for 80 PLUS Gold efficiency, ensuring reliable power delivery. Both options excel in this category, but the SAMA's higher efficiency at a specific load may provide slightly better performance over time.

Build Quality and Warranty

Build quality is essential for ensuring long-term reliability, and both brands offer high-quality components. The SAMA Black is built with premium Japanese capacitors, which are known for their durability and performance. Additionally, it comes with a 5-year warranty, giving users peace of mind about their investment. The CORSAIR CX750M does not specify its capacitor quality but is a reputable brand known for reliability. While it also offers a solid choice, the clear warranty and component quality details from SAMA may give it an edge for reliability-conscious consumers.

Which should you buy?

When deciding between the SAMA Black 850W Power Supply and the CORSAIR CX750M, consider your specific needs. If you're looking for a more affordable option with higher wattage and full modularity, the SAMA is a compelling choice. It is ideal for high-performance builds and boasts excellent efficiency and cooling capabilities. Conversely, if you prefer a well-established brand and can justify the higher price for potentially enhanced support and reliability, the CORSAIR CX750M is also a strong contender. Ultimately, both power supplies offer great features, but the decision hinges on your budget, power requirements, and brand preference.
