ASRock PRO 750G vs SAMA B850 850W ATX Power Supply

Price Comparison

The SAMA B850 is priced at C$74.99, making it the more affordable option compared to the ASRock PRO 750G, which retails for C$89.94. This C$14.95 difference might appeal to budget-conscious buyers seeking a reliable power supply without compromising too much on performance. Both products offer substantial capabilities, but if price is a critical factor, the SAMA B850 provides excellent value for those who need 850W power without the premium cost associated with the ASRock.

Power Capacity

In terms of power capacity, the SAMA B850 edges out the ASRock PRO 750G with its 850W output compared to ASRock's 750W. This additional 100W can be crucial for high-performance systems, especially those equipped with demanding graphics cards or multiple components. The increased capacity of the SAMA B850 allows for more flexibility in configurations, making it a better option for users who plan to upgrade their systems or run high-end components in the future.

Efficiency Ratings

The ASRock PRO 750G boasts an 80 PLUS Gold certification, achieving up to 90% energy efficiency under typical loads. This significantly reduces energy waste and operating costs, making it an excellent choice for environmentally conscious consumers. On the other hand, the SAMA B850 carries an 80 PLUS Bronze certification, which offers over 85% efficiency at typical load. While both units provide decent efficiency, the ASRock’s higher certification means it could lead to lower electricity bills over time, especially if the power supply is used intensively.

Cooling Solutions

When it comes to cooling, both power supplies feature quiet fan technology, but they differ in their design and cooling efficiency. The ASRock PRO 750G is equipped with a 120mm silent cooling fan designed for low-noise operation while effectively managing heat. In contrast, the SAMA B850 utilizes a temperature-controlled fan that ensures quiet operation as well. However, the ASRock's larger fan may provide better cooling performance for extended use, making it suitable for high-performance gaming or workstation settings.

Compatibility

Both the ASRock PRO 750G and the SAMA B850 are compatible with the latest ATX 3.1 and PCIe 5.1 standards, which is essential for users looking to build a future-proof system. The ASRock features a native 12V-2x6 jack, supporting high-performance graphics cards with up to 450W power delivery. The SAMA B850 also supports high-end GPUs, such as the RTX 4090/50 Series, with its own 450W PCIe 5.1 power delivery. Thus, both units offer excellent compatibility, but the ASRock may have a slight edge with its dedicated connection designed for modern graphics cards.

Warranty and Support

Both power supplies come with a 3-year warranty, providing a solid assurance of reliability and durability. The ASRock PRO 750G, however, also emphasizes its commitment to customer support, encouraging users to reach out directly via Amazon for any questions or assistance. While both brands offer similar warranty periods, ASRock's proactive support could be a deciding factor for those who value customer service.

Aesthetics and Cable Management

In terms of aesthetics and cable management, the SAMA B850 offers sleek black flat cables that improve case airflow and enhance overall system aesthetics. This design can be particularly appealing for users who prioritise a clean and organized build. The ASRock PRO 750G doesn't specify its cable design but focuses more on performance features. While both units are functional, the SAMA B850 might be preferable for those who want an attractive and tidy setup.

Which should you buy?

Choosing between the ASRock PRO 750G and the SAMA B850 comes down to your specific needs and budget. If you're looking for a more powerful unit with higher efficiency and solid customer support, the ASRock PRO 750G is a compelling choice, despite its higher price of C$89.94. However, if you're on a tighter budget and require a reliable power supply that still delivers robust performance, the SAMA B850 is an excellent option at C$74.99, especially with its superior power capacity and aesthetic appeal. Ultimately, both power supplies present strong cases, but your decision should align with your performance needs and financial considerations.
