However, after using and testing it in various scenarios with my RX 9070 XT, I can say that it's an excellent PSU. It performs well, is almost silent and the cables are long enough and tidy for my build. They also look great inside my white case. In terms of value for money, this PSU is excellent and comes with all the cables needed for a high-end build. ### ⭐⭐⭐⭐⭐ it’s alr for ur build *by on Reviewed in the United States August 10, 2026* had no problem with it so far ### ⭐⭐⭐⭐⭐ Quiet and ready for those next gen GPUs! *by on Reviewed in the United States June 9, 2025* The NZXT C850 Gold ATX 3.1 is a fantastic power supply—super quiet with zero fan noise under light loads, and fully modular for clean cable management.
