A 6+2 cable example is not an EPS12V 4+4 cable. Device location alone is not a reliable identity test.

Can any eight-position cable power a GPU?
Eight positions do not establish cable identity. The 6+2 PCIe example and the 4+4 CPU example have distinct component roles.
What the evidence supports
Read the PCIe designation and the exact device and PSU documentation together.
What not to conclude
CORSAIR warns that incorrect modular cable types can damage hardware. Location on a motherboard is not proof that the cable is EPS.
Keep this check open
The wire assignment of an unlabeled modular cable is not established by this guide.
Before you choose a part
- Identify the device-side power designation.
- Verify the cable against the PSU’s exact compatibility guidance.
- Do not convert a visual resemblance into an installation decision.

Keep the unknown visible.
What this view supports
- A larger group of 6 beside a smaller group of 2
- The component may be a GPU or another device, including a motherboard
What remains unknown
Cavity keying, wire colors, pin maps and compatibility are intentionally not drawn.
Why no physical view? Linked manufacturer exterior image could not be inspected; no guessed physical housing.
The next useful check
Confirm the PCIe label and the exact equipment and PSU manuals. Keep the modular PSU-end wiring decision separate.

PCIe auxiliary power connector section
Identifies legacy 2x3 and 2x4 PCIe auxiliary-power forms and the 12VHPWR form with twelve larger power contacts plus four smaller sideband contacts. Identification/reference scope only. V36 does not convert this source into a universal pinout, fabrication drawing, electrical approval or end-to-end compatibility verdict.
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.
PCIe 6+2 / eight-pin belongs to auxiliary card power
No automatic cross-use follows from the 2×4 silhouette. Intel identifies the PCIe eight-position auxiliary interface as distinct from the processor +12 V connector. A 6+2 assembly is a cable configuration used in the PCIe card-power context, not a license to interchange with EPS/CPU 4+4 or an arbitrary PSU modular port.
Three checks before proceeding
- Confirm graphics-card requirements for count and placement of supplied power leads.
- Trace each GPU lead back to the exact PSU-approved assembly.
- Use maker-approved cables only and do not bridge incompatible outputs.
One mistake to avoid
Deciding CPU/GPU cable type by contact count without reading the PSU cable’s own marking.
Full technical reading, sources and related identities →Claim-specific evidence remains in the canonical record. Concept diagrams do not show any safe wiring or mechanical mating geometry.
The useful distinction
Recognize it. Then verify it.
The legacy PCI Express auxiliary-power family includes an eight-position 2x4 connector form. [C192A]
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. [C192C]
CORSAIR warns that using the incorrect modular PSU cable type may damage hardware and requires cable-type verification before installation. [C192D]
Intel revision 2.11 describes the PCIe 2x4 connection as a board header and a separate cable-plug harness; these are different component roles. [C192E]
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. [C192F]

Make the next check
Check the exact PSU cable type and the board/card connector designation in both manuals.
- 8-pin CPU power versus 8-pin PCIe auxiliary power
- PCIe 8-pin, 12VHPWR and 12V-2x6 auxiliary power
- T08 · Use the exact PSU and motherboard/GPU approved-cable documentation; do not trial-fit or infer PSU-side pinouts.
Existing source inspection and AI review remain distinct from independent technical review. A matching form does not establish a safe connection.
Recorded variant and source limits
- No mating-face orientation or key geometry is inferred from the assignment table.
- The 2x4 add-in-card header may accept a documented 2x3 plug in the Intel design context; this does not authorize arbitrary cable substitutions.
- Modular PSU-side pinouts are outside this profile.
- Intel ATX v3 PSU PCIe 2x4 (150 W) cable plug: Contact numbers per Table 5-5.
- GIGABYTE GP-UD850GM-A PG5 modular PCIe 6+2 cable, VGA (card) end: Drawing on the cited page.
- Intel rev 2.1a PCIe 2x4, 150 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 eight-pin auxiliary connector: NVIDIA Figure 7 board-header drawing and its POSITION #1 INDICATOR; Table 3 supplies the numbered signals. Cable rear view is not established.

Before you connect
What to check
- Identify the exact connector family and variant from the equipment or cable documentation.
- Keep shape, contact count, protocol, electrical rating and device support as separate facts.
- 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.
What is not established
This field note does not approve a connection, adapter, cable assembly, rewiring scheme or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
