SAMA Black 850W Power Supply - Fully Modular 80 Plus Gold Certified ATX 3.1 & PC vs Redragon RGPS-850W 80+ Gold 850 Watt Power Supply w/Upgraded ATX 3.1 & PCIe 5.1

Price Comparison

The SAMA Black 850W Power Supply is priced at C$89.99, while the Redragon RGPS-850W 80+ Gold Power Supply comes in at C$154.99. This notable price difference of C$65 suggests that the SAMA model may be a more budget-friendly option for consumers looking for quality power supplies. However, the higher price of the Redragon might reflect additional features or performance capabilities that could appeal to more demanding users.

Design and Build Quality

In terms of design, both power supplies feature modern, fully modular designs that promote streamlined cable management. The SAMA Black includes flat cables that enhance airflow and keep builds tidy, which is beneficial for cooling. On the other hand, the Redragon RGPS-850W offers a compact 160mm size, allowing for better chassis compatibility and tidy cable management. Both models also boast the use of high-quality Japanese capacitors, ensuring reliability and stability in power delivery.

Efficiency Ratings

Both power supplies are certified with the 80 PLUS Gold rating, indicating high energy efficiency. The SAMA Black achieves up to 91.15% efficiency at 50% load, which is impressive and contributes to reduced energy waste and lower heat output. The Redragon RGPS-850W also emphasizes energy efficiency, designed to maintain cooler case temperatures and reduce noise. While both units offer excellent efficiency, the SAMA's specific efficiency rating provides a slight edge in quantifiable performance.

Cooling Mechanisms

Cooling is an essential aspect of power supply performance, and both models utilise different approaches. The SAMA Black is equipped with a 120mm ECO fan that features Fluid Dynamic Bearing (FDB) technology, resulting in quiet operation levels as low as ≤20dB-A. In contrast, the Redragon RGPS-850W incorporates a Zero RPM Mode fan that only activates at temperatures above 60℃, promoting silent operation during lower loads. Each model offers effective cooling solutions, but the SAMA may be quieter under load due to its lower noise level.

Compatibility Features

Compatibility is crucial for modern PC builds, and both power supplies are designed to support the latest technology. The SAMA Black is ATX 3.1 and PCIe 5.1 compatible, supporting high-end GPUs like the RTX 3090 Ti and RTX 40 series. Similarly, the Redragon RGPS-850W is also ATX 3.1 and PCIe 5.1 ready, designed for top-tier GPUs including NVIDIA’s 4090 and 4080 series. Both models excel in compatibility, ensuring they can meet the demands of high-performance systems.

Warranty and Reliability

When it comes to warranty, the SAMA Black provides a solid 5-year warranty, which speaks to the manufacturer’s confidence in its durability and performance. The Redragon RGPS-850W does not specify a warranty period in the provided data, potentially leaving users uncertain about long-term reliability. The extended warranty of the SAMA may make it a more attractive option for users prioritising long-term investment in their components.

Aesthetic Features

The Redragon RGPS-850W stands out with its RGB lighting capabilities, offering up to 9 RGB modes with 26 selected colours. This feature allows users to customise their build’s aesthetic, creating a visually appealing setup. In contrast, the SAMA Black focuses more on utility and performance rather than aesthetics, providing a clean and functional design without RGB features. Users seeking a visually striking build may prefer the Redragon, while those prioritising performance may lean towards the SAMA.

Which should you buy?

Choosing between the SAMA Black 850W Power Supply and the Redragon RGPS-850W ultimately depends on your specific needs and budget. The SAMA Black presents a compelling case with its lower price of C$89.99, impressive efficiency ratings, and a solid warranty, making it a great choice for budget-conscious gamers or builders. Conversely, the Redragon RGPS-850W, despite its higher price of C$154.99, offers aesthetic appeal with RGB features and a compact design that may suit certain setups. If you value performance, reliability, and lower costs, the SAMA Black is the way to go. However, if you desire advanced features and aesthetic enhancements, consider the Redragon RGPS-850W.
