Price Comparison
When considering price, the NZXT C850 Gold Core is about 10% cheaper than the MSI MPG A850GS, retailing at $99.99 compared to MSI's $110.99. This cost difference could be significant for budget-conscious consumers. While both power supplies are positioned in the same market segment, the lower price of the NZXT model may appeal to users looking to maximize value without sacrificing performance.
Power Efficiency
Both the MSI MPG A850GS and the NZXT C850 Gold Core are 80 Plus Gold certified, ensuring high energy efficiency. This certification means that both units operate at least 87% efficient at 20% and 100% loads. However, the NZXT unit boasts Cybenetics Platinum efficiency, which indicates even better performance in reducing energy waste and heat generation, especially under demanding loads. This could lead to lower electricity bills over time, making the NZXT potentially more cost-effective in the long run.
Modular Design
The MSI MPG A850GS and NZXT C850 Gold Core are both fully modular, allowing users to connect only the cables they need. This feature is essential for maintaining a clean and organized build, enhancing airflow and aesthetics. The MSI unit, however, doesn't specify additional cable features, while the NZXT model includes embossed cables that are flexible and durable, which can make installation and routing easier.
Cooling and Noise Levels
In terms of cooling and noise, the NZXT C850 Gold Core has a notable advantage with its 135 mm fluid dynamic bearing fan that operates in Zero RPM mode during light workloads. This feature allows for near-silent operation, rated at less than 15 dBA. On the other hand, the MSI MPG A850GS does not specify a fan's noise level, making it unclear how it compares in quiet operation. For users who prioritize a silent gaming experience, the NZXT's advanced cooling technology may be more appealing.
Compatibility
Both power supplies are designed to support the latest generation of graphics cards with PCIe 5.1 and dual 12V-2x6 connectors. However, the NZXT C850 Gold Core explicitly mentions compatibility with modern NVIDIA graphics cards and the ability to support up to three 8-pin PCIe cables. This could provide more flexibility for high-end builds, especially for users who may want to upgrade their graphics in the future.
Warranty and Reliability
The MSI MPG A850GS comes with a robust 10-year warranty, which reflects the manufacturer's confidence in its product's durability and reliability. In contrast, the NZXT C850 Gold Core offers a 7-year warranty. While both warranties are substantial, the longer warranty for the MSI unit may provide peace of mind for those concerned about long-term performance and support.
Customer Trust and Brand Reputation
Both MSI and NZXT are well-respected brands in the gaming community, known for producing reliable components. However, MSI is particularly recognized for its gaming-oriented products, while NZXT is famous for its case designs and cooling solutions. The choice between these brands may come down to personal preference or previous experiences with either company's products.
Which should you buy?
The decision between the MSI MPG A850GS and the NZXT C850 Gold Core ultimately depends on your specific needs. If you're looking for a slightly more affordable option with excellent cooling and silent operation, the NZXT C850 Gold Core is a compelling choice. On the other hand, if you value a longer warranty and prefer a brand with a strong gaming reputation, the MSI MPG A850GS may be worth the extra investment. Both power supplies provide excellent performance, but your priorities will guide the best choice for your setup.
