How to Choose
Add up your CPU TDP and GPU TDP, then add 150-200W for overhead, fans, drives, and transient spikes. For a single RTX 5090 build, 1000W minimum. For dual-GPU LLM rigs, 1200-1600W. 80 Plus Gold is the sweet spot for price and efficiency. Fully modular PSUs make cable management much easier. Check that your case supports the PSU form factor (ATX is standard).
