• Power fluctuations can cause frequent crashes during intensive tasks like gaming, rendering, or machine learning.

Protecting Your Hardware:

• A PSU that’s underpowered or of low quality can overload, potentially damaging your GPU, motherboard, or other components.

Longevity of Components:

• Using a reliable PSU ensures stable power delivery, which prolongs the lifespan of your expensive hardware investments.

Recommended PSU Wattage for the RTX 5090 and RTX 4090

Given the high power demands of these GPUs, here’s a breakdown of the minimum PSU requirements:

GPU	Estimated TDP (Thermal Design Power)	Recommended PSU Wattage
RTX 4090	450W	850W (minimum)
RTX 5090	500W+ (rumored)	1,000W or higher

Why the RTX 5090 Needs More Power:

• The higher CUDA core count and enhanced memory bandwidth increase the power draw.
• Users upgrading to the RTX 5090 should check their current PSU wattage and consider upgrading to at least a 1,000W PSU for stable and reliable performance.

Compatibility and Upgrade Options

If you’re considering either GPU, here’s how to ensure compatibility with your current system:

Check PSU Wattage:

• Open your PC case and check the label on your PSU to confirm its wattage and efficiency rating.

Look for 80+ Certification:

• Ensure your PSU is 80+ Gold certified or higher for better energy efficiency and power stability.

Ensure Proper Connectors:

• Both the RTX 5090 and RTX 4090 require PCIe 5.0 12VHPWR connectors (also known as 12-pin connectors).
• Older PSUs may not have this, so you may need to upgrade to a newer model with native support or use NVIDIA’s included adapter (though native support is preferred for reliability).

Future-Proofing Your PSU:

• If you’re investing in a PSU upgrade, consider going beyond the recommended wattage for future-proofing, especially if you plan to overclock your GPU or add other high-power components like additional SSDs, RAM, or cooling systems.
