Why This Wattage?
Power Calculation
The recommended PSU wattage is calculated based on the total power draw of your CPU (Intel Core i5-13400) and GPU (AMD Radeon RX 9070 XT), 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 AMD's Radeon Chill to dynamically adjust frame rates, reducing GPU power consumption during less demanding scenes.
Utilize the power saving modes in Windows and the BIOS to optimize CPU and overall system power usage during idle periods.
Monitor CPU and GPU temperatures; ensure adequate cooling to prevent thermal throttling, which can impact efficiency.
Special Installation Note
Connect the RX 9070 XT to dedicated PCIe power cables directly from the PSU, avoiding daisy-chaining, to ensure stable power delivery and prevent potential issues under heavy load. Consider using two separate 8-pin (6+2 pin) connectors from the PSU.
Usage Scenarios
AAA Gaming
This PC can handle the latest AAA games at high settings and resolutions, delivering smooth and immersive gameplay experiences.
Video Editing
Capable of editing 4K video footage with ease, rendering projects quickly thanks to the powerful CPU and GPU combination.
Productivity Powerhouse
Ideal for demanding tasks like software development, data analysis, and running virtual machines smoothly without performance bottlenecks.
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 AMD Radeon RX 9070 XT 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 ample, reliable 80+ Bronze power for your i5-13400 and RX 7900 XT, ensuring stable gaming performance.
