Utilizing the ATX v3.0 power standard, the NZXT C1200 Gold pumps up to 600 watts of power to NVIDIA 40-series graphics cards over a single cable while maintaining highly efficient, low-noise performance.
Next-Gen Power
Provides up to 600W of power to PCIe 5.0 GPUs, such as the NVIDIA GeForce RTX 4090 - over a single 16-pin connector.
Future-Proof Design
Built to handle massive power spikes from next-gen GPUs.
High-Quality Components
Constructed with all Japanese 105C-rated capacitors for the highest standard in performance, reliability, and longevity.
Single Cable Connection
Featuring a single 16-pin connection cable—perfect for 40 Series cards. Installation is easier, safer, and less likely to damage parts without requiring any bulky adapters.
Elite Efficiency
With over 90% efficiency at 50% load, the C1200 reduces energy usage to lower monthly costs and extend your PC's lifespan. No wasted energy - it only draws the power your system needs.
Silent Operation
The 135mm PWM fan with a fluid dynamic bearing runs quietly, even at high loads. Zero Fan Mode shuts it off for total silence when under 40% load.
