Family reference
Distinguish internal PC power forms by keyed connector family and documented role. Similar contact counts do not make CPU, GPU and main-power connectors interchangeable.

Recognition & reference
Recognition illustrations are not to scale or fabrication drawings. The label-led symbols below, where present, are not interface geometry. Read the illustration limits in each exact reference; equal image boxes do not establish equal physical sizes.
Computer-generated illustrationP189 / PC power / Connector form
A 24-position shell is not enough to approve a power supply, motherboard or rewiring scheme.
Computer-generated illustrationP190 / PC power / Connector form
An eight-position PC power shell can be confused with PCIe auxiliary power; keying and device documentation matter.
Computer-generated illustrationP191 / PC power / Connector form
A PCIe auxiliary-power connector is not a general-purpose keyed DC connector.
Computer-generated illustrationP192 / PC power / Connector form
This eight-position PC power form is not interchangeable with every 8-pin CPU-power connector.
Computer-generated illustrationP193 / PC power / Connector form
The newer 16-contact form is a separate connector family from the older 2x3 and 2x4 PCIe auxiliary connectors.
Recognition illustration · not to scaleP260 / PC power / Connector form
Physical family recognition never establishes safe GPU power delivery. Cable construction, PSU/device requirements, seating and the exact specification remain safety-critical.
Computer-generated illustrationP367 / PC power / Connector form
Equal counts of four contacts do not establish a safe mechanical mate, cable wiring or interchangeable equipment power connection.
Computer-generated illustrationP368 / PC power / Connector form
Equal counts of four contacts do not establish a safe mechanical mate, cable wiring or interchangeable equipment power connection.
