ModPC’s pins complete the Female PSU / ATX / EPS / PCI power connector. When rebuilding the connectors in your system often the original metal pins cannot be reused. These pins are the optimal supplement for the connectors & couplings, and can also be used to generally replace worn-out pins.
Installation is quick and easy: the pins are simply put on a bared lead end & then fixated by compression of the holding sleeves of the pin with pliers. The installed pin can then simply be inserted into the plastic connector and will lock into place.
