Disclosed embodiments include a modified M.2 interface that is configured to allow an increased current capacity on power-carrying pins. The power-carrying pins are implemented using an alloy that can sustain current levels in excess of those specified in the M.2 standard while remaining within M.2 standard specified temperature limits. Sockets and corresponding cards in embodiments are modified so that a card requiring the higher current capacity cannot fit into a legacy M.2 standard socket, while a legacy M.2 card can fit into a modified high current M.2 socket. Other embodiments may be described and/or claimed.
