Why This Wattage?
Power Calculation
The recommended PSU wattage is calculated based on the total power draw of your CPU (AMD Ryzen 7 5800XT) 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 AMD's Eco Mode in the Ryzen Master software to limit the CPU's TDP and reduce power consumption when maximum performance isn't needed.
Utilize NVIDIA's GeForce Experience to optimize game settings for a balance between visual quality and power efficiency.
Consider undervolting the RTX 5070 slightly using software like MSI Afterburner to reduce power draw without significantly impacting performance.
Special Installation Note
Ensure the 8-pin (6+2) PCIe power connectors are securely connected to the RTX 5070. Although the recommended PSU is 600W, ensure the PSU has sufficient amperage on the 12V rail to accommodate both the CPU and GPU's peak power draw.
Usage Scenarios
High-End Gaming
This PC can handle demanding AAA games at high resolutions (1440p/4K) with smooth frame rates and ray tracing enabled.
Video Editing
Effortlessly edit 4K videos, render complex effects, and enjoy fast export times thanks to the powerful CPU and GPU combination.
AI Development
Train and run machine learning models, experiment with AI algorithms, and develop advanced applications using the GPU's parallel processing power.
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 Thermaltake 600W provides ample, stable power for your 5800XT & RTX 5070, and the 80+ efficiency keeps things running smoothly.
