Count the role, not just the contacts.

Four power-connector labels are separated by documented application and example scope. This is a reading chart, not a pinout or installation guide.

EPS12V / CPU C190C · C190D

Example scope: CORSAIR article example

C190C / P190

CORSAIR illustrates the CPU-power cable role with an EPS12V 4+4 arrangement; the split is an example, not a requirement for every EPS cable.

Cable-division concept only; exact face geometry was not inspected.

Original claim verification: 2026-10-11. Status: source_checked. No independent hardware approval.

C190D / P190

CORSAIR warns that Type 3 and Type 4 modular PSU cables are not compatible with Type 5 power supplies.

This separate PSU-end check is not resolved by identifying an EPS12V component-end connector.

Original claim verification: 2026-10-11. Status: source_checked. No independent hardware approval.

PCIe eight-position auxiliary C192C · C192D

Example scope: CORSAIR article example

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.

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

Original claim verification: 2026-10-11. Status: source_checked. No independent hardware approval.

C192D / P192

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

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