Antec NeoPower 550 550W ATX12V SLI Certified CrossFire Ready Active PFC Power Supply

  • ATX12V
  • 100 - 240 V
The Antec NeoPower 550 offers super quiet operation and high - up to 85% - efficiency thanks to Active PFC (power form correction). This efficiency factor, along with Antec's innovative "straight-through" airflow path allows the fan to run slower – and quieter – as it exhausts heat from the power supply. As a result, you'll save energy – and money – on your power bills each month. The power supply is backwards compatible with all ATX 12V systems while supporting ATX12V v2.2 and EPS12V systems.
With 550 watts of power at your command, dedicated power circuitry delivers a more reliable – and safer – output to your system's components with voltage feedback circuitry and tighter regulation for improved system stability. Maximum, stable power to your CPU is delivered via three +12V output circuits independently of the other components and dedicated power connector supplies energy to any PCI Express graphics card.
The NeoPower 550 is certified Nvidia SLI-ready. In order to reduce cable clutter, the advanced cable management system lets you use only the cables you need to power your system. All of this is backed by Antec's AQ5 5-year warranty.
