8-pin CPU power versus 8-pin PCIe auxiliary powerWhat does the PSU cable and motherboard/GPU manual call this connector? Pin count alone is not enough.↗Legacy PCIe auxiliary power versus 12VHPWRIs this the older 2x3/2x4 family or the separate 12+4-contact 12VHPWR form?↗PCIe 8-pin, 12VHPWR and 12V-2x6 auxiliary powerWhich exact GPU auxiliary-power connector family does the PSU and device documentation require? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.↗

Discovery is not a compatibility verdict.
These discovery surfaces route and reorganize facts already represented in the atlas. They do not add electrical ratings, universal pinouts, measured tolerances, exact-device support, wiring approval or an end-to-end compatibility result.
