Thermaltake and SilverStone Launch Over 3000W PSUs Supporting Up to Four RTX 5090 GPUs

• July 22, 2026

Thermaltake and SilverStone have recently unveiled new power supply units (PSUs) aimed at high-performance workstations featuring multiple powerful graphics cards. These PSUs are built to deliver extreme power levels to support demanding multi-GPU setups, specifically accommodating configurations with up to four NVIDIA GeForce RTX 5090 graphics cards.

Power Solutions for Multi-GPU Workstations

The Thermaltake AX 3200W and SilverStone HELA 3000Rz represent the latest additions in the realm of ultra-high wattage power supplies. The AX 3200W model from Thermaltake is capable of delivering up to 3200 watts of power, while SilverStone’s HELA 3000Rz offers a 3000-watt output. Both units are designed with workstations and professional-grade computing in mind, where multiple GPUs are frequently deployed to handle tasks such as rendering, AI workloads, and complex simulations.

Each power supply features four dedicated 12V power connectors configured as 2×6 pin connectors. This setup ensures that the power supplies can reliably feed multiple high-end graphics cards, which often require substantial power overhead. The four connectors on each unit theoretically provide enough power capacity and physical connectors to run as many as four GeForce RTX 5090 GPUs simultaneously without compromise.

As graphics cards like the RTX 5090 push the boundaries of performance and power consumption, the availability of PSUs capable of supporting multiple cards at these scales is critical for professional users building custom workstations. These new power supplies by Thermaltake and SilverStone respond to the growing demand for reliable, high-capacity power sources in such setups.

Details regarding pricing, exact specifications beyond wattage and connector count, and availability timelines were not disclosed at the time of the announcement. However, the introduction of these models indicates a continued trend toward supporting advanced GPU configurations with sufficiently robust power infrastructures.

Thermaltake and SilverStone’s new PSUs demonstrate the ongoing evolution in power supply solutions tailored specifically for users who require beyond-standard wattage capabilities and connectivity for the latest generation of high-performance graphics hardware.
