Efficiency and Wattage Comparison
Efficiency Rating
The EVGA SuperNOVA holds the 80 Plus Titanium certification, which is the highest standard available for consumer power supplies. This rating ensures that the unit maintains at least 94% efficiency at 115VAC and 96% at 220-240VAC under typical loads. In contrast, the MSI MAG A850GL carries the 80 Plus Gold certification. While Gold is still an excellent standard for energy savings, Titanium represents a tier above in terms of conversion efficiency. If your priority is minimizing energy waste during peak operation, the EVGA model offers a clear technical advantage in certification level.
Wattage Output
Power capacity differs significantly between these two units. The MSI MAG provides 850W of continuous power, which is sufficient for most high-end gaming builds. The EVGA SuperNOVA delivers 1600W, making it suitable for extreme workstations or systems with multiple high-draw components. You need to choose based on your system's total power draw. The MSI unit is likely overkill for average users, while the EVGA may be excessive for standard gaming PCs unless you are planning heavy overclocking or professional rendering tasks.
ATX Version
The MSI MAG A850GL supports the ATX 3.1 standard, which is the latest revision for PC power supply specifications. This version ensures compatibility with modern motherboards and the latest PCIe 5.1 standards. The EVGA SuperNOVA data does not explicitly list its ATX version compliance. While it is a high-end unit, you should verify its specific version compatibility with your motherboard if you require strict adherence to the newest ATX 3.1 guidelines. The MSI unit offers a confirmed advantage in modern specification support.
PCIe Connector Type
For graphics card connections, the MSI MAG includes the 12V-2x6 connector, which is the required interface for PCIe 5.1 graphics cards. This allows you to connect the latest GPUs without needing adapters. The EVGA SuperNOVA data does not specify its PCIe connector type. If you are building a new system with the latest NVIDIA or AMD graphics cards, the MSI unit provides direct compatibility. The EVGA unit may require adapters or older connectors, which could complicate cable management for new builds.
Dimensions and Size
Physical dimensions vary greatly due to the different wattage and internal designs. The MSI MAG is more compact, measuring 8.75 inches in width and 12 inches in length. The EVGA SuperNOVA is wider at 14.5 inches but shorter in length at 3.4 inches. You must check your PC case to ensure the PSU fits. The MSI unit may fit better in standard mid-tower cases, while the EVGA’s unique shape requires a case with specific clearance for its wider profile. Both are fully modular, but space planning is essential.
Which PSU fits your build needs
Gamers with mid-range GPUs needing modern connectors
The MSI MAG 850W supports ATX 3.1 and PCIe 5.1 standards. It includes a native 12V-2x6 connector, simplifying connections for modern graphics cards. Its compact dimensions fit smaller cases better than larger units. The 10-year warranty provides long-term reliability for gaming systems.
