USB 3.0 front-panel 19-pin internal connector

The familiar motherboard USB 3.0 front-panel connector exposes a 19-pin populated internal-header arrangement in Intel’s documented server-board example.

Also called USB 3.0 19-pin header USB 3 front panel header 19-pin USB header internal USB 3 header

This legacy internal USB header is not the same physical interface as the newer USB-IF Key-A front-panel connector for USB Type-C/front-panel use.

Look for

Identify the keyed two-row internal header and verify the motherboard manual; do not force a Key-A cable or external USB plug into this interface.

Recorded variant and source limits
  • Intel’s table groups differential-pair members but does not give V44 a safe basis to assign plus/minus polarity or a physical face-view locator.
  • Motherboard implementation, USB mode, cable construction and front-panel device capability still require exact product documentation.
  • USB3 ICC A - motherboard header (Table 2-1): Figure 2-1 numbering (see connector view_convention).
  • USB3 ICC B - front-panel daughter-card connector (Table 2-2): Contact numbers only; Table 2-3 states the cable joins motherboard pin n to daughter-card pin 20-n.
  • Intel USB3 ICC A (motherboard header): Intel Figure 2-1 numbering.

Use the source-backed form or position count only for identification. Resolve ratings, protocol, direction, wiring, cable construction and exact device support from the relevant equipment and component documentation.

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.

View and evidence limits

Figure 2-1 numbering (see connector view_convention).

  • P263 USB 3.0 19-pin header — **Agree** on 18 of 19 pins in both variants (motherboard and front-panel card) — **Pin 10:** Intel's table labels it "ID" in the signal column but describes over-current protection. Pass A recorded "ID" as verified; pass B marked it unverified because of the conflict. Publish as "ID (Intel's own table also describes it as over-current protection)", not as a settled function.
  • Signal names use the A-side (host) naming; SSRX/SSTX direction perspective is not stated in Table 2-1.
  • The specification covers 19 pins; Figure 2-1 shows an empty bottom-row position under pin 1 and a key on the upper edge, but assigns no number to the empty position and gives no key dimensions in the inspected pages.
  • The figure does not state whether it is a top (mating) view or a solder-side view.
  • No motherboard manual was used; vendor headers may label pin 10 differently.
