SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC vs ASRock PRO 750G

Price Comparison

The SAMA Black 850W Power Supply is priced at C$89.99, while the ASRock PRO 750G comes in slightly lower at C$89.94. Although both products are closely priced, the SAMA offers a higher wattage, making it a more powerful option for users with demanding power needs. This difference could be significant for gamers or professionals seeking to run high-performance components, as the additional wattage may accommodate more intensive setups. Despite the minimal price difference, the power output disparity may influence your purchasing decision based on your system requirements.

Power Output

In terms of power output, the SAMA Black provides a notable 850W, compared to the ASRock PRO's 750W. This 100W advantage means that the SAMA can support more powerful graphics cards and additional components without risk of overloading. If you plan on building a high-performance gaming rig or a workstation with multiple GPUs, the increased capacity of the SAMA may be crucial for maintaining system stability under load. Conversely, the ASRock's 750W can still adequately power medium to high-performance systems, but users with higher demands might find it limiting.

Efficiency Ratings

Both power supplies boast an 80 PLUS Gold certification, but their efficiency levels differ slightly. The SAMA Black claims up to 91.15% efficiency at 50% load, ensuring lower energy waste and reduced heat output. In comparison, the ASRock PRO 750G achieves up to 90% efficiency. While this difference may seem minor, the SAMA's slightly superior efficiency can lead to lower electricity bills and a cooler running system over time, especially during prolonged use. This aspect is particularly beneficial for users focused on energy conservation and long-term savings.

Cooling Solutions

Cooling performance is an essential factor in the longevity of power supplies. The SAMA Black features a 120mm ECO fan with Fluid Dynamic Bearing technology, designed to operate quietly at noise levels as low as 20dB-A. This ensures minimal disruption during gaming or work sessions. In contrast, the ASRock PRO 750G is equipped with a 120mm silent cooling fan, optimized for low-noise operation. While both models focus on quiet performance, the SAMA's advanced bearing technology may offer enhanced reliability and quieter operation under heavy loads, which is an important consideration for noise-sensitive environments.

Compatibility Features

When it comes to compatibility, both power supplies are designed to meet modern standards. The SAMA Black supports ATX 3.1 and PCIe 5.1, making it suitable for the latest GPUs, including the RTX 3090 Ti and the RTX 40 series. The ASRock PRO 750G also complies with ATX 3.1 and PCIe 5.1 standards, ensuring it can power next-generation components effectively. However, the SAMA's native PCIe connectors might offer a slight edge in terms of ease of setup for the latest high-performance graphics cards. This compatibility is vital for users who want to future-proof their builds.

Build Quality and Warranty

In terms of build quality, the SAMA Black is equipped with premium Japanese capacitors, which contribute to stable power delivery and long-term reliability. It also comes with a 5-year warranty, providing added peace of mind for buyers. On the other hand, the ASRock PRO 750G is backed by a 3-year warranty, which, while still respectable, is shorter than that of the SAMA. The use of high-quality components in the SAMA may appeal to users looking for durability and longevity in their power supply, especially for high-performance configurations.

Target Audience

The target audience for these power supplies can significantly influence your choice. The SAMA Black is aimed at gamers and professionals who require a robust power solution for high-performance systems. Its higher wattage and superior efficiency make it an attractive option for heavy users. Conversely, the ASRock PRO 750G is more suited for casual gamers or those with moderate power needs, providing a reliable performance without the demand for extreme wattage. Understanding your specific power requirements will help you decide which product aligns better with your needs.

Which should you buy?

Ultimately, the decision between the SAMA Black 850W Power Supply and the ASRock PRO 750G hinges on your specific needs. If you require higher power output, superior efficiency, and longer warranty coverage, the SAMA Black at C$89.99 is the better option. However, if your power demands are more modest and you prefer a slightly lower price point of C$89.94, the ASRock PRO 750G remains a solid choice. Assess your system requirements and budget to determine which power supply will best serve your needs.
