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.
ATX12V and EPS12V CompatibleCompatible with the ATX12V v2.2 and EPS12V standards, the Antec NeoPower 550 provides maximum power stability to drive the latest Intel and AMD processors as well as other components for desktop and server computer systems.
550W Maximum PowerA maximum power of 550W delivers safe, reliable output for average gaming computer systems.
Highly EfficientProviding up to 85% power efficiency, the Antec NeoPower 550 power supply saves energy and may even reduce your electric bill!
Dual PCI-E ConnectorsWith two 6-pin PCI-E connectors, the Antec NeoPower 550 is ideal for building up a SLI or CrossFire gaming system.
Modular Cable DesignThe modular cable design allows use of only the cables you need resulting in improved internal airflow and reduced system clutter.
NVIDIA SLI CertifiedThe Antec NeoPower 550 power supply has gone through a series of rigorous NVIDIA SLI certification tests for maximum system stability when building NVIDIA SLI PCs.

Highly efficient (upto 85%), one super-silent 80mm fan keeps Neo HE cool; less than 18dBA noise level. Advanced Cable Management System improves internal airflow and reduces system clutter by allowing you to use only the cables you need. Universal Input with Active PFC: Use anywhere in the world without worrying about input voltages; Active PFC improves voltage stability and delivers environmentally-friendlier power. Dedicated Power Circuitry: Delivers safer, more reliable output to your system’s delicate components. Includes dedicated voltage outputs, triple +12V output circuits, voltage feedback circuitry, and tighter ±3% regulation for improved system stability. ATX12V v2.2 and EPS12V compliant; backward compatible with all ATX12V systems. Three +12V output circuits provide maximum stable power for the CPU independently of the other peripherals. Accurate power rating allows Neo HE to deliver its full rated power, 24 hours a day rated at 50ºC. Low-speed 80mm fan delivers whisper-quiet cooling and ensures quiet operation by varying fan speed in response to load and conditions. SATA connectors for your Serial ATA drives. Industrial grade protection circuitry prevents damage resulting from short circuits (SCP), under voltage protection (UVP), power overloads (OPP), excessive current (OCP) and excessive voltages (OVP).
