Why This Wattage?
Power Calculation
The recommended PSU wattage is calculated based on the total power draw of your CPU (Intel Core i7-13700) and GPU (NVIDIA GeForce RTX 4080 SUPER), plus approximately 100W for other components like motherboard, memory, and storage devices.
Extra Headroom
We add an additional 30% headroom to ensure optimal efficiency, handle power spikes, and allow for future upgrades. This ensures your system runs stable and your PSU operates in its optimal efficiency range.
Efficiency Standards
We recommend power supplies with 80 Plus certification, which represents higher energy efficiency and more reliable performance. Power supplies are most efficient at 50-60% load, so having adequate headroom is important.
Power Efficiency Tips
Enable NVIDIA's DLSS Frame Generation in supported games to boost frame rates without significantly increasing power consumption.
Consider undervolting the RTX 4080 SUPER to reduce power draw and heat output while maintaining similar performance levels.
Ensure XMP is enabled for your RAM to optimize performance; however, this may slightly increase power consumption.
Special Installation Note
Given the RTX 4080 SUPER's power demands, ensure the PSU's PCIe power connectors are securely connected to the GPU, preferably using separate cables from the PSU to avoid overloading a single cable.
Usage Scenarios
AAA Gaming
Effortlessly play the latest AAA games at maximum settings with high refresh rates and ray tracing enabled, providing stunning visuals and smooth gameplay.
Content Creation
Quickly render complex 3D models, edit high-resolution videos, and stream gameplay with ease, leveraging the CPU and GPU power for efficient workflows.
AI Development
Train machine learning models, experiment with AI algorithms, and run demanding simulations, utilizing the GPU's parallel processing capabilities.
Installation Tips
Position Properly
Most cases have a dedicated PSU bay at the bottom. Ensure the PSU fan is facing down if your case has bottom ventilation, allowing it to draw cool air from outside.
Cable Management
With modular PSUs, connect only the cables you need. Route cables behind the motherboard tray when possible for better airflow and cleaner appearance.
Proper Connections
Ensure all power connectors are fully seated and locked. The NVIDIA GeForce RTX 4080 SUPER will require dedicated PCIe power connectors from the PSU.
Test Before Completing
Before fully closing your case, connect the essential components and test that your system boots correctly with the new power supply.
The MSI MAG A650BE provides stable, reliable power for your i7-13700 and RTX 4080 SUPER, giving you headroom with its 650W.
