SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC vs be quiet! Power Zone 2 850W ATX 3.1 PSU

Price Comparison

The SAMA Black 850W Power Supply is priced at C$89.99, making it significantly more affordable than the be quiet! Power Zone 2, which retails for C$187.50. This price difference of C$97.51 may be crucial for budget-conscious consumers looking to build or upgrade their systems. While both units deliver 850W of power, the SAMA offers a more cost-effective solution without compromising on essential features, while the be quiet! model targets users willing to invest more for premium efficiency and performance.

Efficiency Ratings

Efficiency is a critical factor in power supplies, and here, the be quiet! Power Zone 2 outshines the SAMA Black. The Power Zone 2 boasts an impressive 80 PLUS Platinum certification, achieving an energy efficiency rating of up to 94.1%, compared to the SAMA's 80 PLUS Gold certification, which achieves up to 91.15% efficiency at 50% load. This means that while both units are efficient, the Power Zone 2 is designed to waste less energy, leading to lower electricity bills and cooler operation, making it a suitable choice for high-performance systems.

Cooling Solutions

Cooling capabilities are essential for maintaining system stability and performance under load. The SAMA Black features a 120mm ECO fan with Fluid Dynamic Bearing technology, achieving noise levels as low as ≤20dB-A. In contrast, the be quiet! Power Zone 2 employs a larger 140mm Pure Wings 3 fan with semi-passive zero-RPM cooling. This means that under low loads, the fan completely shuts off, resulting in silent operation. When both units are under heavy load, the larger fan of the Power Zone 2 is designed to provide more efficient cooling, which could be an advantage for users running demanding applications.

Build Quality and Components

Build quality is paramount in power supplies, and both brands take different approaches. The SAMA Black prides itself on using premium Japanese capacitors, ensuring stable power delivery and long-term reliability, backed by a 5-year warranty. In comparison, the be quiet! Power Zone 2 focuses on German engineering and quality, which is evident in its design and components. While both products promise durability, the choice may come down to brand loyalty or preference for specific manufacturing standards.

Compatibility with Modern Hardware

Both power supplies are designed with ATX 3.1 standards, ensuring compatibility with the latest components. The SAMA Black includes native PCIe 5.1 ports and cables, making it suitable for high-end GPUs like the RTX 3090 Ti and RTX 40 series. Meanwhile, the be quiet! Power Zone 2 also features native integration of the 12V-2x6 connector for next-generation graphics cards, alongside three PCIe 6+2-pin connectors for current models. This makes both units future-proof; however, the be quiet! model may provide a more versatile solution for users planning to upgrade frequently.

Noise Levels

Noise levels are an important consideration, especially for users who prefer a quiet environment. With the SAMA Black operating at ≤20dB-A under load, it is designed to be one of the quieter options available. Meanwhile, the be quiet! Power Zone 2’s semi-passive cooling system means that the fan does not operate at all under low loads, contributing to an even quieter experience. For users prioritizing silence, the Power Zone 2 may be the preferable option, particularly during light usage.

Warranty and Support

Warranty can be a decisive factor for consumers concerned about long-term reliability. The SAMA Black offers a solid 5-year warranty, reassuring buyers of its durability. The be quiet! Power Zone 2 does not specify its warranty period in the provided data, which could leave potential buyers uncertain about long-term support. A well-defined warranty often reflects confidence in the product's longevity and performance, making the SAMA a safer bet in this aspect.

Which should you buy?

Ultimately, the choice between the SAMA Black 850W Power Supply and the be quiet! Power Zone 2 850W ATX 3.1 PSU depends on your individual needs and budget. If you're looking for an economical option that still meets modern power requirements, the SAMA Black at C$89.99 provides excellent value with good efficiency and reliable components. However, if your focus is on maximum efficiency, silent operation, and premium features, the be quiet! Power Zone 2, despite its higher price of C$187.50, may be worth the investment for high-performance builds.
