NZXT C650 650 Watt Power Supply Unit



The new C Series power supply from NZXT features safe, reliable power while ensuring optimal efficiency and quieter performance. Manufactured with high-quality components and backed by a 10-year warranty, the C Series power supplies deliver both peace of mind and clean, reliable power to your PC gaming system.

  • The modular design lets you use only the cables you need, ensuring easier installation, and less clutter. The sleeved main cables look great and resist heat damage as well as fraying, delivering greater durability and longevity.
  • The C series fits any case conforming to the ATX standard with the C650 supporting NVIDIA GPUs up to 3060 and AMD GPUs up to Vega 64.
  • A push of a button enables Zero RPM Fan mode, silencing the fan under low-load conditions. When needed, the 120mm fluid-dynamic bearing fan spins up to efficiently cool the PSU, keeping your system stable and running through even the most intense gaming session.
  • In addition to world-class service and support, NZXT provides a 10-year warranty for the C Series PSU, so you can enjoy a worry-free gaming experience.
