Overview of the MSI MAG A750BE and NZXT C850 Gold Core
The MSI MAG A750BE is a semi-modular power supply priced at $69.99, while the NZXT C850 Gold Core is a fully modular option available for $99.99. This makes the MSI MAG A750BE about 30% cheaper than the NZXT C850 Gold Core. Both power supplies cater to different user needs, with the MSI focusing on efficiency and noise reduction, and the NZXT providing higher efficiency ratings and advanced connectivity options.
Efficiency Ratings
The MSI MAG A750BE boasts an 80 Plus Bronze certification, which ensures a good level of efficiency, typically around 82% or higher at 20%, 50%, and 100% loads. In contrast, the NZXT C850 Gold Core has an 80 Plus Gold certification, indicating its efficiency exceeds 87% at similar load conditions. The higher efficiency of the NZXT unit not only translates to reduced energy consumption but also less heat generation, making it a more suitable choice for high-performance systems.
Modular Design
The MSI MAG A750BE features a semi-modular design, allowing users to connect only the cables they need while keeping the internal layout simpler. This can be beneficial for those building a budget-friendly system with fewer components. On the other hand, the NZXT C850 Gold Core is fully modular, enabling complete customization of cable management. This modularity allows for a cleaner build and easier upgrades, particularly important for performance-driven systems that may require multiple GPU connections.
Cooling and Noise Levels
The MSI MAG A750BE includes a 120mm low-noise fan designed to operate quietly, contributing to a more tranquil computing environment. While exact noise levels aren’t specified, its focus on low noise operation is clear. The NZXT C850 Gold Core, however, takes it a step further with a fluid dynamic bearing fan that features a Zero RPM mode, effectively eliminating fan noise during light workloads. The NZXT is Cybenetics noise certified for near-silent operation at less than 15 dBA, making it a superior choice for users prioritizing a silent setup.
Compatibility and Connectivity
MSI's MAG A750BE is compatible with standard components and provides the essential connections needed for most builds. Conversely, the NZXT C850 Gold Core is ATX 3.1 certified and PCIe 5.1 ready, specifically designed to support next-gen graphics cards, such as those from NVIDIA, with its dual-color 12V-2x6 connector. This forward-thinking design ensures that the NZXT unit can handle the power demands of modern GPUs, making it more future-proof for users looking to upgrade their systems.
Capacitor Quality
The MSI MAG A750BE does not specify capacitor ratings, which can be a concern for those interested in long-term reliability. In contrast, the NZXT C850 Gold Core features premium 105°C-rated capacitors, which are designed to ensure stable performance across a wide range of system loads. High-quality capacitors can significantly impact the overall longevity and reliability of a power supply, making the NZXT a more robust option for demanding setups.
Warranty and Support
The MSI MAG A750BE comes with a 5-year warranty, providing decent coverage for users. However, the NZXT C850 Gold Core offers a more generous 7-year warranty, reflecting the manufacturer’s confidence in their product's durability and performance. A longer warranty can be a decisive factor for consumers, especially in high-stakes environments where system failure can lead to significant downtime.
Which should you buy?
Choosing between the MSI MAG A750BE and the NZXT C850 Gold Core ultimately depends on your specific needs and budget. The MSI MAG A750BE is a solid choice for users looking for a cost-effective power supply that prioritizes low noise and basic efficiency. However, if you require a more advanced, fully modular unit with superior efficiency, better cooling, and future-proofing capabilities, the NZXT C850 Gold Core is worth the additional investment. At $99.99, the NZXT is approximately 30% more expensive but may provide better long-term value for performance-oriented users.
