12V-2x6 is a 16-circuit PCIe CEM5 wire-to-board power connector system with 12 power circuits and 4 signal circuits in the documented Molex implementation.
Also called 12V-2x6 PCIe CEM5 12V2x6 12V2x6 16-circuit GPU power
The cited 12V-2x6 example is a board header, not an approval for an arbitrary cable or PSU.
Verify the 12V-2x6 designation rather than assuming every 16-contact GPU-power plug is the earlier 12VHPWR form, and follow the exact PSU/GPU documentation.

No. The cited Molex 2191161161 is a specifically identified 12V-2x6 board header. A generic 16-contact shape is not that product identity.
The exact Molex part description establishes a header with 12 power and 4 signal circuits.
An unmarked cable end is not identified as that board header by counting contacts.
Revision-specific contact geometry and a complete cable/device power result remain unverified.
C260A (private workspace) — Molex identifies part 2191161161 as a PCIe CEM5 12V-2x6 header with 16 circuits, configured as 12 power and 4 signal circuits.
V43 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction, protocol guarantee or end-to-end compatibility proof. S280
C260B (private workspace) — Molex specifies 2191161161 as a right-angle, male, shrouded three-row 12V-2x6 header with 16 circuits arranged as 12 power plus 4 signal, a 3.00 mm mating pitch, polarization to the mating part and first-mate/last-break behavior.
V44 component-level mechanical/interface boundary only; no 12VHPWR pin-map carryover, safe-power calculation, insertion-depth approval, cable-bend rule or installation approval. S291
C193A (private workspace) — Intel describes the 12VHPWR auxiliary-power connector form as twelve larger power contacts plus four smaller sideband contacts and distinguishes it from legacy 2x3/2x4 PCIe forms.
V36 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction or end-to-end compatibility proof. S199
Manufacturer evidence is not an independent review, wiring assignment or hardware test.

Part details and PCIe CEM5 12V2x6 product specification
Identifies a 16-circuit PCIe CEM5 12V-2x6 header with 12 power and 4 signal circuits. V43 does not generalize current capacity or approve cabling. Identification/reference scope only. V43 does not convert this source into a universal pinout, fabrication drawing, electrical approval, protocol guarantee or end-to-end compatibility verdict.
Part details and product customer drawing 2191160001-SD
Engineering-scoped inspection of Molex 2191161161: 16 circuits arranged as 12 power plus 4 signal, three rows, 3.00 mm mating pitch, right-angle male shrouded header, polarization and first-mate/last-break property. V44 does not copy a 12VHPWR logical pinout onto 12V-2x6, does not calculate safe power, and does not publish insertion-depth, bend-radius or assembly approval.
Canonical evidence is retained separately. Existing claim dates are unchanged; only new V118 claims have a new inspection date. No live electrical, energized probing, forced mating or optical-port inspection is recommended.
No. Intel’s ATX design-guide revision history identifies 12V-2x6 as the successor to the 12VHPWR PCB header, with revised engagement of power and sideband contacts. Intel says the cable-plug side remained compatible with the new header definition. This is not permission to reuse a damaged connector, mix modular PSU leads, or assume a GPU supports a particular sustained power level.

The useful distinction
12V-2x6 is a 16-circuit PCIe CEM5 wire-to-board power connector system with 12 power circuits and 4 signal circuits in the documented Molex implementation. [C260A]
Intel revision 2.11 locates longer power contacts and shorter sideband contacts in the revised 12V-2x6 PCB header. [C260C]
Intel revision 2.11 describes an additional 12V-2x6 PCB header in a modular power supply when using a double-ended 12V-2x6 cable. [C260D]
Molex lists keying to the mating part as No and polarization to the mating part as Yes for 2191161161; those separately named fields should not be collapsed into one physical-keying claim. [C260E]
PC internals · a documented check
The cited Intel revision locates the contact-length changes in the PCB header: longer power contacts and shorter sideband contacts. It distinguishes H++ from the earlier H+ marking. That is not a cable-condition or whole-system approval. C260C · C193C
| Check | Documented distinction | Boundary |
|---|---|---|
| Earlier designation | Intel distinguishes H+ as the previously defined 12VHPWR connector. C193A · C193C | Twelve power contacts plus four sideband contacts alone do not identify the revised header. |
| Revised board header | The 12V-2x6 PCB header changes power and sideband engagement lengths. C260C | Do not relabel a cable plug as the PCB component that contains that change. |
| PSU-side role | The cited guide describes another 12V-2x6 PCB header for a double-ended cable at a modular PSU. C260D | This is a defined configuration, not a claim about every modular supply. |
| Cable provenance | The PSU maker’s cable-type restrictions remain a separate check. C192D | A generation label does not approve an arbitrary modular cable. |
