New 3000W Asus PSU Handles 4 RTX 5090s in a Single PC

Powering a multi-GPU configuration has traditionally been a challenge for PC enthusiasts, especially with the rising power demands of modern graphics cards like Nvidia’s RTX 5090. Asus recently unveiled a groundbreaking 3000W power supply unit (PSU) designed to seamlessly support up to four RTX 5090 GPUs in a single computer system. This new powerhouse redefines what’s possible in gaming, rendering, and deep learning rigs, enabling unprecedented GPU density and performance.

Introducing the Asus 3000W PSU: Power Meets Efficiency

The new 3000W Asus PSU is engineered for high-end multi-GPU builds and workstation PCs requiring massive electrical power. With efficiency rated at 80 Plus Titanium certification, this PSU ensures maximum energy conversion while minimizing heat and electricity consumption.

• Power Output: 3000 watts continuous, peaking at 3200 watts
• Modularity: Fully modular cables tailored for clean builds and easy installation
• Connectors: Exclusive support for up to 4 PCIe 16-pin connectors for RTX 5090 GPUs
• Cooling System: Advanced dual-fan design with smart sensor control to keep temps low
• Protections: Over-voltage, under-voltage, over-current, short-circuit, and thermal shutdown safeguards

Why You Need a 3000W PSU for 4 RTX 5090 GPUs

The RTX 5090 cards are the latest flagship GPUs from Nvidia, known for their incredible performance but also high power draw. Each RTX 5090 can consume up to 600 watts under full load, meaning four of them could collectively demand up to 2400W just for the GPUs alone.

Considering additional power consumption from the CPU, motherboard, drives, cooling systems, and peripherals, a 3000W PSU becomes essential for stable operation. Under-powering a multi-GPU setup can lead to instability, crashes, or hardware damage, which no enthusiast or professional wants.

Key Benefits of Using the Asus 3000W PSU with 4 RTX 5090s

• Stable Power Delivery: Ensures consistent energy supply to all GPUs for sustained high performance during gaming or rendering.
• Future-Proofing: Designed with headroom for future power demands or added components without needing an upgrade.
• Improved Overclocking Potential: Stable and clean power allows enthusiasts to push GPUs further safely.
• Reduced Cable Clutter: Fully modular cables reduce internal airflow obstruction and heat buildup.
• High Efficiency: Reduces electricity bills and environmental impact thanks to 80 Plus Titanium certification.
