Super Flower Unleashes 2800W Leadex Titanium PSU: World’s First ATX Power Supply With 4x 12V-2x6 Connectors for Extreme Multi-GPU Builds
Super Flower, the acclaimed Taiwanese power supply manufacturer, unveiled what is now the world’s most powerful consumer-grade ATX PSU: the Leadex 2800W Titanium. Now officially on sale, this PSU offers a whopping 2800W of continuous power and is the first ATX unit in the world to deliver four native 12V-2x6 (16-pin) connectors, making it capable of powering four GeForce RTX 5090 GPUs simultaneously.
Unprecedented Power for Workstation-Class Builds
The Leadex 2800W shatters existing wattage records for desktop PSUs, eclipsing even the SilverStone Hela 2050R Platinum, one of the few other options to break the 2000W barrier. With ATX 3.1 and PCIe 5.1 compliance, this PSU is engineered to meet the demands of next-generation graphics cards such as NVIDIA’s RTX 50-series, specifically the power-hungry RTX 5090.
Though quad-GPU consumer gaming setups have become obsolete, this unit is tailor-made for AI, ML, deep learning, and 3D rendering workstations, where multiple GPUs still reign supreme.
