Price Comparison
The SAMA B850 is priced at C$74.99, making it significantly more affordable than the CORSAIR CX750M, which retails for C$124.99. This means the SAMA B850 is C$50 cheaper, which could be a decisive factor for budget-conscious consumers. Despite the price difference, both power supplies offer features that justify their respective costs. The SAMA B850 provides a cost-effective solution for those looking for efficient power supply options without breaking the bank.
Power Capacity
The SAMA B850 delivers a robust 850W of power, ideal for high-performance setups, particularly those using advanced graphics cards like the RTX 4090 and 50 Series. In contrast, the CORSAIR CX750M offers a maximum of 750W, which is still substantial but falls short of the SAMA's capacity. The extra 100W from the SAMA could be beneficial for users planning to upgrade their systems or run power-hungry components. This makes the SAMA B850 a more future-proof option for gamers and power users alike.
Efficiency Ratings
In terms of efficiency, the SAMA B850 boasts an 80 PLUS Bronze certification, ensuring over 85% efficiency at typical loads. This feature helps reduce electricity costs, making it an economical choice in the long run. Meanwhile, the CORSAIR CX750M also adheres to the latest ATX 3.1 and PCIe 5.1 standards, but its efficiency rating isn't specified in the available data. However, the SAMA B850's clear efficiency rating provides a more transparent expectation for consumers concerned about energy consumption.
Cooling Performance
The SAMA B850 includes a temperature-controlled fan that operates quietly while ensuring optimal cooling performance, which is essential for maintaining system stability during intense workloads. On the other hand, the CORSAIR CX750M features a 120mm low-noise fan designed to run silently under low to medium loads. Both power supplies prioritise quiet operation, but the SAMA B850 specifically highlights its cooling efficiency, which could be a plus for users who value a silent PC experience.
Design and Aesthetics
The SAMA B850 is equipped with sleek black flat cables that not only facilitate easy cable management but also enhance overall system aesthetics and airflow within the case. In comparison, the CORSAIR CX750M features a semi-modular design, allowing users to connect only the cables they need. While both designs offer practical benefits, the SAMA B850’s focus on aesthetics and airflow may appeal more to users prioritising a clean build.
Warranty and Protection Features
When it comes to warranty and protection, the SAMA B850 offers a 3-year warranty along with multiple protection features, including OVP, OCP, OPP, and SCP. This comprehensive protection plan offers peace of mind for users. The CORSAIR CX750M does not specify its warranty terms in the provided data, which could be a potential drawback for consumers who seek assurance regarding their purchase. In terms of long-term reliability, the SAMA B850 stands out by clearly outlining its protection features.
Compatibility
Both the SAMA B850 and the CORSAIR CX750M are ATX 3.1 and PCIe 5.1 ready, ensuring compatibility with the latest motherboards and high-end GPUs. The SAMA B850 explicitly mentions its capability to support cutting-edge GPUs with up to 450W of PCIe 5.1 power delivery. The CORSAIR CX750M also supports the newest Nvidia RTX 50-series GPUs without needing adapters, making it versatile for current and future builds. This compatibility factor is crucial for those wanting to invest in a power supply that will remain relevant as technology evolves.
Which should you buy?
Ultimately, the choice between the SAMA B850 and the CORSAIR CX750M boils down to individual needs and budget. The SAMA B850 stands out with its lower price point of C$74.99, higher power capacity of 850W, and clear efficiency rating, making it a strong contender for users seeking value and performance. Conversely, the CORSAIR CX750M, priced at C$124.99, offers a solid semi-modular design and compatibility with the latest GPU standards, appealing to those who might prefer a more established brand. If budget and power capacity are your primary concerns, the SAMA B850 is the clear winner. However, if you are willing to invest a bit more for brand reputation and modular capabilities, then the CORSAIR CX750M could be the better choice for you.
