NZXT C1000 Gold ATX 3.1 (1000W)
An enthusiast-tier 1000W unit, the NZXT C1000 Gold is fully modular, 80 Plus Gold rated, and carries the native 12V-2x6 connector for RTX 50 Series cards. It is a sensible value pick for single-GPU Blackwell builds and quieter systems leaning on its Japanese capacitors. With no notable drawbacks, the main question is simply whether you need a full kilowatt.

Verdict
Best for
- 1000W Gold value builds
- RTX 50 Series single-GPU systems
- quiet builds with Japanese caps
Who should skip this
- RTX 5090-class builds — 1000W is tight for the top GPU tier; a 1200W gives safer transient headroom
- Mainstream single-GPU rigs — a 5070-class build runs fine on 850W for less money
- Silence-absolute builders — value Gold units don't match premium boards' idle/load acoustics
