Why This Wattage?
Power Calculation
The recommended PSU wattage is calculated based on the total power draw of your CPU (Intel Core i5-14500) and GPU (NVIDIA GeForce RTX 5070), 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 power saving features in Windows and NVIDIA control panel to reduce idle power consumption.
Monitor CPU and GPU temperatures to ensure efficient cooling and prevent thermal throttling.
Avoid using unnecessary peripherals or software running in the background to minimize power draw.
Special Installation Note
With the RTX 5070 likely requiring a dedicated PCIe power connector, ensure the selected PSU has the correct number of connectors for the GPU before installation, and that they are firmly seated.
Usage Scenarios
AAA Gaming
The RTX 5070 and i5-14500 can handle the latest AAA titles at high settings with smooth frame rates.
Video Editing
Efficiently edit 1080p and 4K video, render projects quickly, and handle demanding video editing software.
Productivity Powerhouse
Effortlessly multitask with demanding applications, run virtual machines, and handle large datasets with ease.
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 5070 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 A550BN provides reliable 80+ Bronze power for your i5-14500 and RTX 3070, all in a compact, budget-friendly package.
