Redragon RGPS-850W 80+ Gold vs SAMA White 650W Power Supply - Fully Modular 80

Price Comparison

When comparing the Redragon RGPS-850W and the SAMA White 650W power supplies, the SAMA White is significantly more affordable, priced at $62.99 compared to the Redragon RGPS-850W, which costs $124.99. This makes the SAMA about 50% cheaper than the Redragon, which could be a deciding factor for budget-conscious consumers. The price difference highlights that while both power supplies carry an 80 Plus Gold certification, consumers may need to consider whether the extra capability of the Redragon justifies its higher price.

Power Output

The Redragon RGPS-850W provides a robust 850 watts, making it ideal for high-performance gaming rigs and demanding applications. In contrast, the SAMA White delivers 650 watts, which is still suitable for mid-range builds but may limit performance with high-end components like the latest GPUs. This 200-watt difference means that the Redragon RGPS-850W can accommodate more powerful graphics cards, providing greater flexibility for future upgrades, particularly if you're planning to use GPUs from the Nvidia RTX 30 or 40 series.

Efficiency Ratings

Both power supplies boast an 80 Plus Gold certification, which indicates that they operate efficiently, with the SAMA White achieving up to 91.15% efficiency at 50% load. The Redragon RGPS-850W also emphasizes energy efficiency, leading to cooler case temperatures and reduced noise. While both power supplies are designed for efficiency, the SAMA's higher efficiency rating at a specific load can contribute to lower energy bills over time, making it a smart choice for environmentally-conscious users.

Cooling Solutions

The Redragon RGPS-850W features a smart ECO low-noise RGB fan that only operates when temperatures exceed 60℃, ensuring a quieter operation during normal use. On the other hand, the SAMA White uses a 120mm ECO fan with Fluid Dynamic Bearing (FDB) technology, which operates at noise levels as low as 20dB-A. If noise levels are a primary concern, the SAMA may be the better option, as its design focuses specifically on achieving quiet operation, making it suitable for both gaming and professional environments.

Build Quality

In terms of build quality, both power supplies utilize premium materials. The Redragon RGPS-850W is built with 100% Japanese capacitors, which are known for reliability and durability, ensuring stable power delivery. Similarly, the SAMA White also features high-quality Japanese capacitors, contributing to its stability and long-term reliability. Both brands emphasize the importance of quality components, making them trustworthy choices for users looking for longevity in their power supplies.

Modular Design

The Redragon RGPS-850W and the SAMA White both offer fully modular designs, allowing users to connect only the cables they need, which promotes better cable management and airflow. The SAMA White's flat cables are specifically designed to enhance airflow and simplify the installation process, while the Redragon’s modular cables also aim to reduce clutter. This shared feature is important for users who prioritize a clean and organized build, especially in compact cases where space is at a premium.

Compatibility with Modern GPUs

Both power supplies are designed to support the latest graphics cards. The Redragon RGPS-850W is ATX 3.1 and PCIe 5.1 ready, allowing for compatibility with high-performance GPUs like the Nvidia RTX 40 series. The SAMA White also meets these standards and is capable of supporting GPUs up to the RTX 40 series. However, the Redragon's higher wattage and additional features, such as the included 12VHPWR cable, position it as a more future-proof option for users planning to utilize top-tier graphics hardware.

Which should you buy?

Deciding between the Redragon RGPS-850W and the SAMA White 650W power supplies ultimately comes down to your specific needs and budget. If you require a higher wattage for demanding builds and appreciate features like RGB lighting and a smart cooling fan, the Redragon RGPS-850W may be worth the investment at $124.99. However, if you're looking for a budget-friendly option that still offers excellent efficiency and modularity, the SAMA White at $62.99 provides solid performance without breaking the bank. Each power supply has its strengths, so consider your configuration and future upgrade plans when making your choice.
