SAMA B850 850W ATX Power Supply vs Redragon RGPS-850W 80+ Gold 850 Watt Power Supply w/Upgraded ATX 3.1 & PCIe 5.1

Price Comparison

The SAMA B850 850W ATX Power Supply is priced at C$74.99, while the Redragon RGPS-850W 80+ Gold 850 Watt Power Supply is significantly higher at C$154.99. This represents a price difference of C$80.00, making the SAMA a more budget-friendly option. For users who are price-sensitive or are building a system on a tighter budget, the SAMA offers excellent value without compromising on essential features. However, the higher price of the Redragon may reflect its advanced features and certifications, appealing to users who are willing to invest more for enhanced performance and efficiency.

Efficiency and Certification

Efficiency is a crucial factor for power supplies, and in this comparison, the Redragon RGPS-850W stands out with an 80 Plus Gold certification, indicating higher energy efficiency compared to the SAMA B850, which is 80 Plus Bronze certified. The Redragon’s Gold certification ensures over 90% efficiency at typical loads, leading to lower electricity costs and cooler operating temperatures. In contrast, the SAMA achieves over 85% efficiency. While both power supplies support high-end GPUs, the Redragon's superior efficiency could be a deciding factor for users looking to optimise their energy consumption and reduce overall system heat.

Cooling Performance

Cooling performance is essential for maintaining system stability, and both power supplies feature intelligent cooling solutions. The SAMA B850 utilises a quiet fan cooling system that operates based on temperature control, ensuring low noise levels while effectively cooling the unit during operation. The Redragon RGPS-850W, however, takes this a step further with its Zero RPM Mode, where the fan only activates when the temperature exceeds 60°C. This feature can result in a quieter computing environment during light usage. Users who prioritise silent operation may favour the Redragon for its advanced fan management.

Compatibility with Modern Hardware

Both power supplies are designed to support modern hardware, including the latest motherboards and high-end GPUs. The SAMA B850 is ATX 3.1 and PCIe 5.1 ready, supporting graphics cards such as the RTX 4090/50 Series with a substantial 450W PCIe power delivery. The Redragon RGPS-850W also features ATX 3.1 and PCIe 5.1 readiness, but it offers enhanced performance for the latest GPUs, including a 200% total power excursion and 300% GPU power excursion capabilities. For users building high-performance systems with the latest components, the Redragon’s specifications may provide an edge.

Build Quality and Reliability

Build quality and reliability are paramount for power supplies, and here the Redragon RGPS-850W excels with its use of 100% Japanese capacitors. This choice contributes to greater reliability and durability, ensuring stable performance even under heavy loads. In contrast, the SAMA B850 does not specify the materials used in its construction, which could be a consideration for users prioritising long-term reliability. For gamers and professionals who demand unwavering performance, the Redragon may be the preferred choice due to its quality components.

Aesthetic Appeal

Aesthetics can play a significant role in a PC build, and both power supplies offer unique design elements. The SAMA B850 features sleek black flat cables that not only enhance cable management but also improve airflow within the case, creating a clean look. The Redragon RGPS-850W, on the other hand, includes an RGB lighting feature with up to 9 modes and 26 colour options, allowing users to customise their build's illumination. For those who enjoy personalising their setup, the visual appeal of the Redragon might be more enticing, while the SAMA caters to users seeking a more understated design.

Warranty and Protection Features

Warranty and protection features are crucial for peace of mind when investing in hardware. The SAMA B850 comes with a 3-year warranty and includes multiple protections such as Over Voltage Protection (OVP), Over Current Protection (OCP), Over Power Protection (OPP), and Short Circuit Protection (SCP). The Redragon RGPS-850W also offers similar protections and is equipped with advanced safety features to ensure stable operation. While both power supplies provide solid warranties, the choice might rest on the overall quality perception of the brands and their service reliability.

Which should you buy?

Ultimately, the choice between the SAMA B850 and the Redragon RGPS-850W will depend on your specific needs and budget. If you are looking for a cost-effective solution that still provides solid performance for standard builds, the SAMA B850 at C$74.99 is an attractive option. However, if you are aiming for a high-performance system with advanced cooling, higher efficiency, and aesthetic customisation, the Redragon RGPS-850W at C$154.99 offers significant advantages that may justify the additional expense. Consider your priorities—whether it’s budget, efficiency, aesthetics, or build quality—when making your decision.
