Power Supply Unit NZXT C1000 Gold 1000 W

NZXT C1000 Gold 1000 W is an ATX 3.1 compatible power supply unit that provides 1000 watts of continuous power with 80 PLUS Gold efficiency. The fully modular PSU is built with 100% Japanese capacitors, a 135 mm fluid dynamic bearing fan with Zero Fan Mode, and a compact form factor to simplify cable management and improve airflow. It includes a full cable set, a 24-pin ATX motherboard connector, and is rated for input voltages from 100–240 V at 50/60 Hz.

Advantages

The unit offers high efficiency (80 PLUS Gold and Cybenetics Gold), low acoustic noise (Cybenetics A rating and Zero Fan Mode under 50% load), and improved voltage stability thanks to Japanese capacitors. A 12V-2x6 GPU cable supports up to 600 W for NVIDIA GeForce RTX 40 Series cards. The fully modular design and compact dimensions aid clean builds, and a 10-year warranty provides long-term support.

Suitable for

• High-performance gaming PCs with RTX 40 Series GPUs
• Workstations requiring stable 1000 W power delivery
• Compact builds where efficient cable management and airflow are important
• Systems prioritising low noise operation

How to use

Install the PSU into a compatible ATX case following the motherboard and case manufacturer instructions. Connect the 24-pin ATX and required CPU and PCIe cables to the motherboard and components, using only the modular cables needed for your build to reduce clutter. Ensure input voltage on the wall outlet is within 100–240 V and attach all connectors firmly before powering on the system. For GPUs up to NVIDIA GeForce RTX 40 Series, use the 12V-2x6 cable to supply up to 600 W where applicable.

Recommendations

Place the PSU so intake and exhaust are unobstructed to maintain airflow. Use the modular cables provided and route them to minimise interference with case fans. Regularly check cable connections and keep the interior free of dust to preserve efficiency and cooling performance.
