SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC vs MSI MAG A850GN PCIE5

Overview of the SAMA Black 850W Power Supply

The SAMA Black 850W Power Supply is a fully modular unit that promises excellent efficiency and compatibility with high-end components. Priced at C$89.99, it supports the latest ATX 3.1 standards and comes with PCIe 5.1 ports, making it a suitable choice for modern gaming rigs and workstation builds. The power supply boasts dual Gold certifications, achieving up to 91.15% efficiency at 50% load, which enhances its appeal for energy-conscious users.

Overview of the MSI MAG A850GN PCIE5

The MSI MAG A850GN PCIE5 is a non-modular power supply that offers essential features for gamers and professionals alike, priced at C$99.99. This unit is also ATX 3.1 ready and features native PCIe 5.1 connectors, ensuring compatibility with the latest NVIDIA GeForce RTX 40 and 50 series graphics cards. Additionally, it holds an 80 Plus Gold certification, which signifies high efficiency, although specific efficiency metrics are not disclosed.

Design and Build Quality

The design of the SAMA Black 850W emphasizes a fully modular approach that facilitates streamlined cable management. This design allows users to connect only the necessary cables, resulting in a cleaner build and improved airflow. In contrast, the MSI MAG A850GN features a non-modular design, which may lead to more clutter in the case as all cables are fixed. Both units are built to high standards, but the modular design of the SAMA offers a distinct advantage for users prioritizing aesthetics and airflow.

Efficiency and Performance

Efficiency is a critical factor in power supplies, and the SAMA Black stands out with its ability to achieve up to 91.15% efficiency at 50% load. This not only reduces energy waste but also contributes to lower heat output, potentially prolonging the lifespan of both the power supply and connected components. The MSI MAG A850GN is also 80 Plus Gold certified, ensuring it operates with high efficiency, but does not provide specific performance metrics, making it less transparent than the SAMA model.

Cooling Solutions

Cooling is essential for maintaining system stability, especially under heavy loads. The SAMA Black 850W is equipped with a 120mm ECO fan featuring Fluid Dynamic Bearing (FDB) technology, which allows for quiet operation with noise levels as low as ≤20dB-A. This is particularly beneficial for users who prefer a silent computing environment. The MSI MAG A850GN does not specify the type of cooling fan it uses, which could mean less optimized cooling performance or higher noise levels under load, although it does claim to have industrial-level protections.

Warranty and Reliability

Both power supplies offer a 5-year warranty, which reflects confidence in their reliability and longevity. The SAMA Black 850W is built with premium Japanese capacitors, known for their durability and stable power delivery, further enhancing its reputation for reliability. The MSI MAG A850GN also emphasizes reliability with industrial-level protections, including OVP, OCP, OPP, OTP, and SCP, but lacks the mention of high-quality capacitors, which could be a factor for discerning users.

Price Comparison

At C$89.99, the SAMA Black 850W is the more budget-friendly option compared to the MSI MAG A850GN, which is priced at C$99.99. This C$10 difference may seem minor, but for users working within a fixed budget, it could influence the decision significantly. The additional features and certifications of the SAMA, combined with its lower price, may present a more attractive value proposition.

Which should you buy?

In conclusion, choosing between the SAMA Black 850W Power Supply and the MSI MAG A850GN PCIE5 largely depends on your specific needs and preferences. If you prioritise a fully modular design, superior efficiency, and quiet operation, the SAMA Black at C$89.99 is the better choice. However, if you prefer a more straightforward, compact solution with solid protections, the MSI MAG A850GN, despite its higher price of C$99.99, might suit your needs better. Ultimately, the SAMA Black offers more versatility and performance for its price, making it a strong contender in the power supply market.
