P368 / PC power / Connector

Miniature four-position floppy-drive power housing

The miniature floppy-drive connector uses a distinct four-position housing; TE 171822-4 is a named wire-to-board receptacle housing and Intel marks the floppy-drive power section historical.

Also called mini floppy drive power Berg-style 4-pin floppy power small 4-pin floppy power AMP 171822-4 example

Equal counts of four contacts do not establish a safe mechanical mate, cable wiring or interchangeable equipment power connection.

Look for

Compare the miniature four-cavity housing, retention feature, and specific part label; a similarly counted full-size peripheral plug is a different system.

The useful distinction

Recognize it. Then verify it.

The miniature floppy-drive connector uses a distinct four-position housing; TE 171822-4 is a named wire-to-board receptacle housing and Intel marks the floppy-drive power section historical. [C368A]

TE identifies a 2.5 mm centerline for 171822-4 rather than the 5.08 mm value on 1-480424-0; matching position count is not a mateability verdict. [C368B]

TE drawing 171822 revision L5 shows a narrow housing with four small rectangular face openings and a central retention feature; the study does not provide contact positions or fitting dimensions. [C368C]

Intel ATX 336521 version 2.01 names AMP 171822-4 in the explicitly historical floppy-drive power-connector subsection headed Do Not Include. This does not impose a current-PSU connector requirement. [C368D]

Before you connect

What to check

  1. Identify the exact connector family and variant from the equipment or cable documentation.
  2. Keep shape, contact count, protocol, electrical rating and device support as separate facts.
  3. Do not force, rewire or adapt a connector from this recognition record; resolve the remaining requirements first.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.
