Less Wires. Less Heat.

Traditional Full 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
  • Draw less wall power which save 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.
