Why This Wattage?
Power Calculation
The recommended PSU wattage is calculated based on the total power draw of your CPU (AMD Ryzen 7 9800X3D) 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 Windows/OS power saving features when not gaming to reduce power consumption and heat output.
Close background applications when gaming to free up system resources and reduce power consumption.
Schedule regular dust cleaning to maintain efficient cooling and lower power requirements.
Special Installation Note
When connecting your AMD Radeon RX 9070 XT, use separate PCIe power cables directly from the PSU rather than daisy-chained connectors for better power delivery stability.
Usage Scenarios
1440p Gaming
Enjoy smooth 1440p gaming experience at high settings in most modern games.
Content Creation
Handle video editing and streaming at 1080p with good performance.
Productivity
Great for multitasking with several applications open simultaneously.
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.
