Price Comparison

The MSI MAG A750GLS is priced at $89.99, making it about 28% cheaper than the Redragon RGPS-850W, which retails for $124.99. This notable price difference may influence budget-conscious buyers who are looking for a quality power supply without overspending. The MSI offering provides a solid option for those wanting a reliable performance while saving money, especially considering its robust features and long warranty. On the other hand, the higher price of the Redragon does come with additional wattage and features, which may justify the cost for users needing more power and advanced capabilities.

Power Output

When it comes to power output, the Redragon RGPS-850W has the upper hand with an impressive 850 watts, compared to the MSI MAG A750GLS's 750 watts. This 100-watt difference makes the Redragon suitable for high-performance setups, especially those utilizing multiple GPUs or demanding components. The MSI model, while slightly lower in output, is still capable of powering high-energy devices effectively, especially with its native 12V-2x6 connectors that support PCIe 5.1 GPUs. Users with moderate gaming or computing needs may find the 750 watts sufficient, while enthusiasts may lean toward the additional wattage offered by the Redragon.

Efficiency Ratings

Both power supplies hold an 80 PLUS Gold certification, meaning they operate with up to 90% efficiency. This efficiency ensures that both models provide excellent performance while minimizing wasted energy and heat generation. The MSI MAG A750GLS emphasizes its low-noise operation, making it an attractive choice for users who prioritize quiet performance. The Redragon RGPS-850W also boasts a smart ECO low-noise RGB fan that only activates under certain temperature conditions, providing both efficiency and quieter operation. This similarity in efficiency ratings indicates that both products are designed to meet the needs of gamers and professionals seeking reliable power solutions.

Build Quality and Components

The MSI MAG A750GLS features a durable design with an LLC half-bridge and DC-to-DC converter, ensuring a reliable output with multiple protection features. In contrast, the Redragon RGPS-850W is built with 100% Japanese capacitors, which are known for their reliability and durability. This choice of components means that the Redragon may offer superior longevity and stability under load. Both models come with fully modular cables, which enhance cable management and airflow within cases, but the Redragon's use of flat cables could provide a slight edge in tidiness. Users looking for long-term reliability may favor the Redragon due to its high-quality components.

Size and Compatibility

The MSI MAG A750GLS is compact, measuring 150 mm in length and width, allowing it to fit comfortably in most PC cases. The smaller size can be advantageous for builds with limited space. However, the Redragon RGPS-850W is slightly larger at 160 mm, which may limit its compatibility with tighter cases. That said, its larger size allows for more robust cooling solutions, which could be beneficial for high-performance setups. Gamers and builders with spacious cases may not find the size to be a significant issue, but those with compact setups may prefer the MSI model for its smaller footprint.

Features and Functionality

The Redragon RGPS-850W comes equipped with multiple advanced features, including RGB lighting and a Zero RPM mode for its fan, which operates silently until temperatures reach 60°C. This feature enhances the overall user experience by providing visual appeal and energy efficiency. The MSI MAG A750GLS, while lacking RGB features, focuses on essential performance with its native 12V-2x6 connectors and low-noise operation. Users who appreciate aesthetics and customizable lighting may lean toward the Redragon, while those prioritizing straightforward functionality might prefer the MSI.

Warranty and Support

The MSI MAG A750GLS offers an impressive 10-year warranty, reflecting the manufacturer's confidence in the product's durability and reliability. This extended warranty can provide peace of mind for users investing in a power supply. In comparison, the Redragon RGPS-850W does not specify its warranty period, which could be a consideration for potential buyers. A longer warranty often indicates a commitment to quality, so the MSI's 10-year coverage may sway users toward its purchase, especially for those concerned about long-term performance.

Which should you buy?

The decision between the MSI MAG A750GLS and the Redragon RGPS-850W ultimately hinges on individual needs and preferences. If budget is a primary concern, the MSI model at $89.99 offers excellent value with its solid performance and long warranty. For users who require higher wattage and advanced features like RGB lighting, the Redragon RGPS-850W, despite its higher price of $124.99, presents a more powerful option with enhanced capabilities. Consider your specific power requirements, aesthetic preferences, and budget constraints to make the best choice for your setup.
