Recorded variant and source limits
No mating-face orientation or key geometry is inferred from the assignment table.
This profile is not a modular PSU-side pinout and is not a substitute for the power-supply manufacturer documentation.
Intel rev 2.1a PCIe 2x3, 75 W: Numbered assignments only. The retrieved Intel section supplies a table but no numbered mating-face or wire-side drawing; spatial orientation is UNVERIFIED. Do not mirror these numbers onto an unidentified cable end.
NVIDIA GRID K2 six-pin auxiliary connector: Use NVIDIA Figure 6 board connector drawing and its explicit #1 PIN and #4 PIN callouts. Table 2 defines numbers. No cable wire-side mapping established.
C191E / S570 separately describes the six-position PCIe connector body and the two-position detachable portion of a 6+2 cable end. The two-position portion is context only; it is not a second position count for this six-position form. Exact part, key geometry and cable assembly remain unresolved.
Intel documents a 2x3 PCIe add-in-card auxiliary-power connector form in the cited ATX design guide.
