How they differ

Legacy PCIe auxiliary power, 12VHPWR and the revised 12V-2x6 header are distinct identification scopes.

Intel separates the older PCIe form from the power-plus-sideband 12VHPWR family. S199 · S199
Intel identifies H+ with the earlier connector and H++ with the revised PCB connector; keep the marking and revision statement with its source. S561
The revised contact-length features belong to the PCB header. P260 cable-housing gallery views are not header-revision evidence and are omitted from these general comparison pictures. S280 · S561

What this comparison does not establish: A connector family, count or cable picture does not approve a particular PSU/GPU cable assembly. S561 · S489

Choose the next check

Read exact PSU/GPU and component revision documentation; do not choose a live-power connection by an illustration.

Mini DisplayPort shape also appeared on Thunderbolt 1/2 products, so function still needs device evidence.DVI-D dual-link vs DVI-I dual-linkDVI-D and DVI-I use related shells but have different contact arrangements. The analog-contact area is a key physical distinction.

S563 · Molex 2191161161 — exact part fields and drawing boundary

Molex · Manufacturer / product-owner domain · inspected 2026-10-12 · due 2027-01-10

Within inspection window

Scoped support: The part-specific text lists keying and polarization as separate fields. The page alone does not establish an inspected drawing revision or authorize borrowing geometry from a differently numbered image. Earlier canonical source observations are retained, not overwritten.

Not established / limitations: No independent review, wiring, current rating, mating or fabrication approval. Retrieval status and document revision retained.

Locator: Exact part 2191161161: first-mate/last-break, keying, polarization, orientation, circuit configuration and mounting fields. Linked image path ends 2191160161; image bytes and exact drawing remained unavailable.

Trace 12 claims to their source records

C192A · P192

Intel documents a 2x4 PCIe add-in-card auxiliary-power connector form in the cited ATX design guide.

Claim scope: V36 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction or end-to-end compatibility proof.

Source links: S199 · Evidence trail → (private workspace)

C192C · P192

CORSAIR describes the eight-position PCIe cable end as a 6+2 arrangement and distinguishes it from EPS12V; some motherboards also use PCIe power connectors.

Claim scope: Do not infer cable role solely from the equipment category or position count.

Source links: S474 · Evidence trail → (private workspace)

C192D · P192

CORSAIR warns that using the incorrect modular PSU cable type may damage hardware and requires cable-type verification before installation.

Claim scope: The component-end PCIe role is separate from exact CORSAIR PSU cable compatibility; no cross-brand pinout is inferred.

Source links: S489 · Evidence trail → (private workspace)

C192E · P192

Intel revision 2.11 describes the PCIe 2x4 connection as a board header and a separate cable-plug harness; these are different component roles.

Claim scope: Printed page 59 only. The guide-specific connection description is not a PSU-side socket assignment or permission to reuse an unknown cable.

Source links: S561 · Evidence trail → (private workspace)

C192F · P192

CORSAIR documents PCIe-power inputs on some motherboards as well as graphics cards; mounting on a motherboard does not by itself identify an EPS12V input.

Claim scope: The final clause is an identification inference from the explicit counterexample, not a claim about every motherboard.

C193A · P193

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.

Claim scope: V36 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction or end-to-end compatibility proof.

Source links: S199 · Evidence trail → (private workspace)

C193C · P193

Intel revision 2.11 identifies H+ with the previously defined 12VHPWR connector and distinguishes the revised 12V-2x6 PCB connector with H++.

Claim scope: Printed page 63. A label comparison is not an assessment of an actual cable, seating, available power or exact manufacturer part.

Source links: S561 · Evidence trail → (private workspace)

C193D · P193

Intel version 2.01 describes two original 12VHPWR housing options differentiated by sideband-contact protection.

Claim scope: Historical text only; neither option’s geometry was visually inspected in this round. A later 12V-2x6 illustration is not substituted.

C260A · P260

Molex identifies part 2191161161 as a PCIe CEM5 12V-2x6 header with 16 circuits, configured as 12 power and 4 signal circuits.

Claim scope: V43 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction, protocol guarantee or end-to-end compatibility proof.

Source links: S280 · Evidence trail → (private workspace)

C260C · P260

Intel revision 2.11 locates longer power contacts and shorter sideband contacts in the revised 12V-2x6 PCB header.

Claim scope: Printed page 63, qualitative difference only. No contact lengths, dimensional tolerance, unknown-part classification or seating verdict is supplied.

Source links: S561 · Evidence trail → (private workspace)

C260D · P260

Intel revision 2.11 describes an additional 12V-2x6 PCB header in a modular power supply when using a double-ended 12V-2x6 cable.

Claim scope: Printed page 63. This described arrangement does not mean every PSU provides that interface or accepts an arbitrary cable.

C260E · P260

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.

Claim scope: Exact text fields only, including their naming distinction. Uninspected geometry and mating suitability remain unknown; inherited generation observations are not silently revised.
