Features

XFX 850W Power Supply

SolidLink™ Power Supplies
Less Wires. Less Heat.

XFX 850W Power Supply

SolidLink Fully Modular PSUs don't have as many primary wires - instead we use pin lag that directly connects to the connector's daughter board.

XFX 850W Power Supply

Traditional fully modular PSUs tend to have a bundle of cables which are connected to the connector daughter board which generate heat causing Wattage loss.

SolidLink™ Technology Difference

  • Drastically reduces the lost Wattage
  • Draws less wall power which saves you money
  • Replaces traditional wired connections with direct pin-to-port connections
  • Reduces heat generated by wires
  • Reduces lost Wattage giving you clean, consistent high quality voltage

Hybrid mode when activated, allows your fan to stay off when your computer is idle but turns on automatically when the PSU needs it.
