850 W ATX Gold power supply

The NZXT C850 Gold delivers 850 watts of clean, stable power for high-performance gaming PCs. It carries 80 PLUS Gold certification for optimal efficiency. A fully modular design lets builders connect only the cables they need. Sleeved main cables resist heat damage and fraying.

Suits multi-GPU gaming builds; not for compact cases

This unit suits gaming PCs with multiple GPUs or higher power requirements, including SLI or Crossfire configurations. It supports NVIDIA GPUs up to 3090 and AMD GPUs up to RX 6900 XT. Builders needing a smaller form factor should look elsewhere because the PSU length is 150 mm. Zero RPM fan mode silences the 135 mm fluid-dynamic bearing fan under low-load conditions.

Fits standard ATX cases; frees cable space

The supply fits any case conforming to the ATX standard. Included cables cover a 24-pin ATX connector, two 4+4-pin CPU connectors, three 6+2-pin PCIe connectors, two SATA cables and two peripheral cables. Four 6-32 mounting screws and a US AC power cord are also provided. The 10-year warranty backs the high-quality components inside.

Perguntas sobre este artigo

Do I need an ATX-compatible case to fit this 150 mm long PSU?

Yes, the unit is 150 mm long and built to the ATX form factor, so it fits any case that conforms to the ATX standard.

Can I use the included 6+2-pin PCIe cables with an older graphics card that only needs a 6-pin connector?

Yes, each 6+2-pin cable splits so you can plug in just the 6-pin portion for older GPUs while leaving the extra 2 pins unused.

How do I know the zero-RPM fan mode is actually active?

Under light loads the 135 mm fluid-dynamic bearing fan stops spinning completely; you can verify it is working by confirming the fan stays still during idle or low-power tasks.
