Dimension Scores
The 1000 watts, 80 PLUS Gold and Cybenetics Gold efficiency, and ATX 3.1 compliance with a 600W 12V-2x6 connector position it for top-tier performance.
Zero Fan Mode provides silent operation under 50% load and it has a Cybenetics A Noise Level rating, but some users report audible fan noise under heavy loads.
Utilizes 100% premium Japanese capacitors for improved hold-up time and minimal ripple noise, backed by a 10-year warranty.
It is fully modular, which aids in cable management, but the stiffness of the cables and the tricky 12V-2x6 connector insertion are drawbacks.
Best For
- Powering high-end gaming PCs equipped with NVIDIA RTX 40 Series GPUs.
- PC builds where low noise levels are prioritized during light to moderate system usage.
- Systems demanding stable and efficient power delivery for demanding CPU and GPU combinations.
- Builders seeking a power supply with a 10-year warranty for long-term reliability.
Not Recommended For
- Ultra-silent PC builds that consistently operate under heavy, sustained loads.
- Budget-constrained builds where a 1000W power supply is significantly more wattage than required.
- Users who frequently swap out or customize their power supply cables with non-standard options.
Watch Out For
- The included cables are stiff, making neat cable management a frustrating experience, especially in smaller cases.
- Inserting the 12V-2x6 cable requires significant force and a confirmed click; improper seating risks damaging the connector.
- Despite the 'low-noise' claims, the fan can become audible under heavy system loads, contradicting expectations for silent operation.
- At 7.87 lbs, this PSU adds considerable weight to a build, which might be a concern for those aiming for a lighter system.
- Proprietary cable connectors mean you're stuck with NZXT's cables if you want to maintain warranty and compatibility, limiting customization.

What Buyers Say
While the NZXT C1000 Gold ATX 3.1 is praised for its robust power delivery and quiet operation at lower loads, a recurring theme in user feedback points to challenges with its physical aspects. Many users find the included cables to be notably stiff, making clean routing a frustrating endeavor. Additionally, the 12V-2x6 connector, crucial for modern GPUs, often requires excessive force to fully seat, leading to concerns about potential damage if not handled carefully. Despite its efficiency certifications, some report the fan becoming audible when the system is under significant stress, which can detract from an otherwise quiet build experience.
“Man, this thing powers my 4090 no problem, but getting those stiff cables to bend where I needed them was a nightmare, and that 12V-2x6 plug felt like I was gonna break something trying to get it in all the way!”
Common Praise
- Delivers stable power for high-wattage GPUs, including NVIDIA RTX 40 Series cards.
- Operates silently during light to moderate system usage due to the Zero Fan Mode.
- Fully modular design simplifies cable routing and reduces internal case clutter.
- High-quality internal components, specifically 100% Japanese capacitors, contribute to reliability.
- The 10-year warranty provides a strong sense of long-term assurance.
- ATX 3.1 compliance and the 12V-2x6 connector are considered future-ready for new GPU generations.
Common Complaints
- The included cables are stiff and difficult to bend, complicating neat cable management.
- The 12V-2x6 connector requires significant force and careful seating to ensure a proper, secure connection.
- Fan noise becomes noticeable when the PSU is under heavy load, despite claims of low noise.
- Proprietary cable connectors limit options for aftermarket cable customization.
- The PSU's weight of 7.87 lbs is heavier than some competitors, which can impact overall build weight.
Ownership Tips
- The white finish looks really clean in a matching build, but it definitely stands out if your other components are black or mismatched.
- You really have to push that 12V-2x6 cable in until you hear a solid click; otherwise, you'll be troubleshooting power issues on your GPU.
- Even with Zero Fan Mode, the fan can spin up quite audibly under sudden, high power draws, breaking the silence unexpectedly.
- The included fully modular cables, while functional, are quite rigid, making tight bends and aesthetic routing a constant battle.
