Building a 2400W Multi-GPU Workstation: Reliability of Dual PSU Setups
Generic_Name_Here · reddit · 2026-08-02
A developer is building a 'render monster' workstation packed with GPUs (like RTX Pro 6000s and 5090s) aiming for a total of 2,400W of graphics power, paired with a Threadripper Pro 9975WX.
Limited by 110V wall power, standard high-wattage single PSUs (like the 2500W models) are not an option. The author asks the community for advice on the safety and reliability of dual PSU configurations, hoping to avoid janky crypto-mining rigs and ensure stability for expensive hardware.
