Is it Safe to Use a GPU Cable Extender with Missing Pins?

It's generally not recommended to use a GPU cable when it's missing pins. Some people might say it's okay for lower models, but there's a real risk—especially if you plan to upgrade in the future and might forget that the cable is defective. You're better off returning it for a full replacement.

I completely agree with the other responses. Using a cable with missing pins can lead to power issues or failures, which could damage your components. It's always best to play it safe—return that cable!
