Features:

Drawn from the user manual and packaging this information is common to all three power supplies.

  • DC to DC Convertor Design - Provides superior dynamic response, greater system stability and maximizes the 12VDC rail output.
  • Conductive Polymer Aluminum Solid Electrolytic Capacitors - Ensures operational stability at extreme conditions.
  • Active Power Factor Correction [99% PF Typical] - The "active" solution is the professional solution to power factor correction to reduce line loss and power distortion.
  • High +12V Output - Enhances +12V current capability increases utilization possibilities and ensures there is enough power to support the system's +12V hungry components.
  • Ultra Ventilation [Grid Structure] - Grid ventilation holes designed to optimize airflow for improved cooling and reduced noise.
  • Multi-GPU Technologies Supported - 6-Pin & 8-Pin PCI-E connectors to support all GPU platforms.
  • All-in-One DC Cabling Design - Supports PC, IPC, workstations and server systems.
  • Universal AC Input [Full Range] - Plug and run safely anywhere in the world.
  • 5 Year Limited Warranty** - Our commitment to superior quality.

**European customers must register their product on www.xfxforce.co.uk within 30 days of purchase to upgrade their standard 3 year warranty to a 5 year extended warranty.
