Overview

The NZXT C1000 PSU (2022 model, part number PA-0G1BB-US) is a fully modular ATX power supply unit rated at 1000W with 80PLUS GOLD certification. It features black sleeved cables and a matte black finish, allowing for clean cable management inside the PC case. This unit is designed to pair with high-end graphics cards such as the NVIDIA GeForce RTX 30 series and AMD Radeon RX 6000 series. A microcontroller (MCU) based protection mechanism continuously monitors current, voltage, and output wattage to ensure stable and reliable power delivery. With a 1000W capacity, this PSU provides ample headroom for high-end gaming PCs and creative workstations. Its efficiency exceeds the 80PLUS GOLD standard by up to 2% at 50% load, resulting in lower heat dissipation and quieter operation.

Compatibility Guide

The NZXT C1000 PSU conforms to the standard ATX form factor and fits most mid-tower and full-tower cases. Its depth is approximately 160mm, so cases with generous cable management space are recommended. Connectors include: ATX 24-pin (main), EPS 12V 4+4-pin (CPU), PCIe 6+2-pin (GPU), SATA, and peripheral (Molex). Being fully modular, unused cables can be detached to improve airflow and aesthetics. It is compatible with ATX, Micro-ATX, and Mini-ITX motherboards. However, some compact Mini-ITX cases may not accommodate a 160mm deep PSU, so always verify the case's PSU clearance before purchasing.

Product Info

The NZXT C1000 PSU (2022) was released in 2022 and sits in the mid-to-high tier of the power supply market. It carries 80PLUS GOLD certification, with a claimed efficiency of over 92% at 50% load. The unit is backed by a 10-year warranty, offering long-term peace of mind. Positioned competitively within the 1000W 80PLUS GOLD segment, it offers excellent value for builders assembling high-end gaming rigs. The fully modular design and black sleeved cables appeal to enthusiasts who prioritize both performance and aesthetics.

Best Use Cases

High-end gaming PC builders: Ideal for systems with NVIDIA GeForce RTX 3080/3090 or AMD Radeon RX 6800 XT/6900 XT, providing ample power headroom even with overclocking. Creative workstation users: For video editing, 3D rendering, or other sustained high-load tasks, the 80PLUS GOLD efficiency keeps heat and noise in check. * Cable management enthusiasts: The fully modular design and black sleeved cables make it easy to achieve a clean, professional-looking build.

Things to Consider

With a 1000W capacity, this PSU is overkill for mid-range builds (e.g., RTX 4060 + Core i5). A 750W or 850W unit would be more cost-effective for such configurations. This unit does not support the ATX 3.0 or ATX 3.1 standards. It lacks a native 12VHPWR / 12V-2x6 connector, so users of the latest GeForce RTX 40 or RTX 50 series GPUs will need to use the included PCIe 6+2-pin cables along with the GPU's bundled adapter. Always check your case's PSU clearance before purchase, as some compact cases may not accommodate the 160mm depth of this unit.
