MINI 12 PIN DESIGNED FOR RTX 30 SERIES Specifically engineered for NVIDIA GeForce RTX 30 Series Founders Edition graphics cards (3090/3080/3070/3060/3050) that feature the Mini 12 Pin power port. This cable provides a direct connection from your modular PSU to your GPU without the bulky adapter that comes in the box. CRITICAL NOT 12VHPWR / NOT FOR RTX 40/50 SERIES This cable features the original Mini 12 Pin connector used on RTX 30 Series GPUs. While it physically fits 12VHPWR ports (RTX 40/50 Series), it lacks the 4 sense pins required for proper power negotiation on newer GPUs. For RTX 40/50 Series, please use a 12VHPWR (12+4 pin) cable. EXACT COMPATIBILITY SELECT YOUR PSU BRAND CRITICAL: EVGA and Seasonic use different pinouts on the PSU side. Please select the correct version for your power supply.
