This 550Watt peak power supply uses Active Power Factor Correction (Active PFC) to increase efficiency, resulting in less wasted power for a given workload. We’ve tested several Active PFC supplies from other companies and found that to a unit, they decrease wasted power considerably. It’s good to see this feature reaching a broader audience. Dual-PCI Express video card power connectors are also featured, making this PSU certainly suitable for SLI (or Crossfire) systems.
