FIELD REFERENCE / MAIN & AUXILIARY POWER

Identify the role.
Then identify the cable.

A motherboard connector, an auxiliary-power cable and a bare housing answer different questions. Keep each identity attached to its evidence.

01 / ROLE

What is being powered?

Main motherboard power and add-in-card auxiliary power are not interchangeable jobs.

02 / CABLE

Which power supply is it for?

The equipment-end shape is not evidence that a modular cable matches a different PSU.

03 / COMPONENT

What is actually pictured?

The named 24-position housing shown here is not identified as a complete ATX harness.

ROLE / CABLE TYPE / HOUSING / EVIDENCE
