EXTreme PowerMass High-Current Connectors

Molex’s high-current board-to-board modular connectors offer multiple power ratings for maximum flexibility

Image of Molex's EXTreme PowerMass™ High-Current Connector Molex’s EXTreme PowerMass connectors are designed to support power supplies and systems that require a very high current transfer in challenging and thermal-constrained spaces. These connectors complement Molex's robust power connector offering.

Intensifying Molex’s approach to provide high current density and a customer-configurable design, these connectors offer a nearly unlimited range of power and signal module design options, providing customer-specific interconnect solutions for AC and DC power requirements. EXTreme PowerMass is a high-current board-to-board modular connector system, providing 350 A per inch.


  • Multiple power ratings (150 A, 80 A, and 40 A) provide maximum flexibility for customer design requirements
  • Die-cast or plastic guides offer rugged blind-mating capabilities
  • Sequential power-blade and signal-pin lengths facilitate post-mate and pre-mate options
  • One of the highest capacity board-to-board power connectors on the market with 350 A per inch current density
  • Press-fit and solder-board termination for easy and reliable PCB mounting options
  • Modules assembled to metal stiffener assures true position and flexible module placement
  • Less than 1 mΩ resistance (plane-to-plane) at end-of-life provides minimum heat generation with maximum current transfer
