High density plus (HD+) card edge power connectors reportedly deliver the highest current density of any card edge power connectors.

Capable of supporting power supplies up to 3kW. Designed to enable systems with increasing power requirements in next-generation data centers. Deliver current density at 15A/2.54mm and support 2000-3000W power supplies for data center equipment. Have 1.27mm signal contact pitch and 5.08mm power contact pitch with a working voltage of 60V DC. Offer low contact resistance due to dual-layer design of DC power contacts and pass-through pins, which provide multiple mating/contact points to the PCB.
