    "Tidy little cable...I could have use extension to address this but that means longer cables to get tidy and I don't trust them much with 300W+...Works great and definitely give the founders cards a better clean look. Most colored extensions for these cards are not correctly pinned out and can make the card run poorly or cause crashes!"
