Extended Product Information

FAQs

What is the warranty duration for the NZXT C850 Gold Core Power Supply?

The NZXT C850 Gold Core Power Supply comes with a generous 7-year warranty.

Is the NZXT C850 compatible with modern graphics cards?

Yes, the NZXT C850 Gold Core Power Supply features several PCIe cables and supports ATX 3.1 and PCIe 5.1 with a dedicated 12V-2x6 connector designed to support the latest graphics cards.

How efficient is the NZXT C850 Gold Core Power Supply?

The NZXT C850 is 80 PLUS Gold certified and Cybenetics Platinum certified, delivering up to 90% energy efficiency, which leads to reduced energy costs and heat generation.

Does the PSU fan operate quietly?

Yes, it features a 135mm fluid dynamic bearing fan with Zero RPM mode, operating quietly and only spinning up when necessary. It is Cybenetics Lambda A+ certified for low noise levels.

Can I use this PSU in any PC case?

The C850 Gold Core has a compact ATX size (150mm L x 150mm W x 86mm H), designed to fit easily into most standard ATX cases, offering good space for cable management and cooling.

What does ATX 3.1 support mean for my build?

ATX 3.1 support means the PSU is designed to meet the stricter power excursion requirements of modern, high-power components like the latest GPUs, ensuring stable and reliable power delivery.

What is the benefit of a fully modular design?

A fully modular design allows you to connect only the cables you need. This results in a cleaner build, improved airflow within the case, and easier cable management.

Troubleshooting

PSU not powering on

Ensure the power cable is securely connected to both the PSU and the wall outlet. Verify that the PSU switch on the back is in the 'on' position. Check that all internal power cables are firmly seated on the motherboard and PSU.

System instability or random shutdowns

Confirm that the PSU is not overloaded. Ensure all power cables, especially the CPU and GPU power connectors, are properly seated. Check for any firmware updates for your motherboard or GPU that might improve power management.

Excessive fan noise

The fan features Zero RPM mode and only spins under load. If noise is constant, check if the PSU is under unexpectedly high load. Ensure there is adequate airflow around the PSU and case to prevent it from running too hot.

Components not detected after installation

Double-check all modular cable connections to the PSU and the components. Ensure you are using the correct cables for each component (e.g., PCIe for GPU, EPS for CPU).

Pros and Cons

Pros

  • High efficiency (80 PLUS Gold and Cybenetics Platinum)
  • Supports the latest standards (ATX 3.1, PCIe 5.1)
  • Quiet operation with Zero RPM mode
  • Fully modular for clean builds
  • Compact design for wider case compatibility
  • Reliable power delivery for demanding components

Cons

  • Higher cost compared to non-modular or lower-efficiency PSUs
  • Specific connector for PCIe 5.1 might require adapter for older GPUs
  • The compact size might be less ideal for extremely large enthusiast cases
  • No explicit mention of specific cable lengths, which can impact routing in larger builds

Setup, Compatibility & Care

Setup:

  1. Ensure the PC is powered off and unplugged from the wall.
  2. Open the PC case and locate the PSU mounting area.
  3. Install the NZXT C850 Gold Core PSU using the provided screws.
  4. Connect only the necessary modular cables to the PSU and your components (motherboard, CPU, GPU, storage drives, etc.).
  5. Use the dual-colour 12V-2x6 connector for compatible PCIe 5.1 GPUs. For GPUs requiring standard 8-pin PCIe power, use the appropriate included cables.
  6. Route cables neatly using the case's built-in management features.
  7. Close the case and connect the power cord.

Compatibility:

  • Motherboards: Compatible with standard ATX motherboards.
  • CPUs: Supports modern CPUs requiring standard EPS connectors.
  • GPUs: Fully compatible with PCIe 5.1 GPUs via the 12V-2x6 connector. Also supports most previous-generation GPUs that use standard 8-pin PCIe power connectors (up to three 8-pin PCIe cables are available).
  • Cases: Designed for standard ATX cases with dimensions of 150mm (L) x 150mm (W) x 86mm (H).

Care:

  • Keep the PSU vents clear of dust and obstructions to ensure proper airflow.
  • Periodically clean the PSU fan and surrounding area using compressed air or a soft brush.
  • Avoid overloading the PSU beyond its 850W capacity.
  • Do not attempt to open the PSU casing, as this can be dangerous and will void the warranty.
