What customers say
Customers highly value the NZXT C1000 Gold for its modern compatibility and reliable performance. Full ATX 3.0 compliance and the native PCIe 5.0 connector offer excellent future-proofing for new systems and high-end GPUs. A major highlight is the robust and stable power delivery, ensuring consistent operation under heavy loads. Users consistently praise the unit's quiet operation, noting the fan is virtually silent during typical use, enhancing the overall system experience.

While some modular cables are noted as slightly stiff, this is a minor point against the excellent value provided by its advanced features and dependable performance.
Know before you buy
Yes, the C1000 Gold includes a dedicated 12V-2x6 connector, which is the updated standard for modern high-performance GPUs, allowing for a direct, secure connection without needing adapters.
Zero Fan Mode allows the 135mm fan to stop spinning entirely during low-load tasks, such as web browsing or light office work. This ensures the power supply remains completely silent until the system temperature or power draw increases enough to require active cooling.
Yes, the C1000 is fully modular, meaning every cable can be detached from the power supply unit. This is highly beneficial for cable management, as you only need to plug in the specific cables your build requires, reducing clutter inside your PC case.
Yes, it follows the standard ATX form factor with dimensions of 6.3 x 5.91 x 3.39 inches. It should fit comfortably in any mid-tower or full-tower case designed for standard ATX power supplies.
The 80 PLUS Gold certification indicates that the unit is at least 87% efficient at various load levels. This results in less wasted energy as heat, lower electricity costs, and quieter operation compared to less efficient power supplies.
The unit is built with 100% premium Japanese capacitors, which are widely considered the industry standard for durability and stability. This quality, combined with a 10-year limited warranty, ensures the PSU is designed to last through multiple PC upgrade cycles.
