Modular Cable Pinouts

Cable Compatibility: EVGA & Corsair

DANGEROUS — INCOMPATIBLE

DANGER! Mixing cables between EVGA and Corsair modular power supplies will cause immediate short circuiting and hardware failure.

❌ EVGA and Corsair modular ports are pin-incompatible. Mixing cables will likely trigger over-current/short-circuit protection or cause permanent hardware damage.

Why Mixing modular cables is dangerous

Unlike the component-facing side of modular cables (which are standardized ATX connections), the connector slots on the physical power supply housing vary widely across brands and individual PSU generations. Manufacturers like Corsair and Seasonic route ground, 12V, 5V, and 3.3V power rails to different pins on the PSU ports. If you plug a cable wired for Seasonic into a Corsair power supply, it can send 12V down a ground wire, instantly destroying connected RAM, motherboard components, or GPUs.
