This PCIE 5.0 12VHPWR power adapter cable converts three standard PCIE 8pin PSU power outputs into a 16pin (12+4Pin) male connector for modern highpower graphics cards. It allows you to use traditional power supplies to power RTX 3090Ti, 4070Ti, 4080, 4090 and other GPUs equipped with 12+4pin power interface, without replacing your whole power supply unit.
Built with highquality tinnedcopper conductors, this cable minimizes voltage loss and heat buildup, maintaining consistent power delivery when GPU runs heavy gaming, rendering and computing tasks. Molded locking connectors clip firmly onto graphicscard and PSU power sockets, effectively preventing intermittent power disconnection caused by case vibration or cable stress inside computer chassis.
Flexible cable body supports convenient internal routing, helping you arrange clean cable layout inside ATX and midtower PC cases. Each 8pin female port connects to separate PSU PCIE 8pin power cables for balanced current distribution. No driver or firmware setup required, direct plugandplay for desktop hardware assembly and GPU upgrade projects.
Important prepurchase note: Each 8pin power input should connect to independent PSU PCIE cable; daisychaining multiple ports on one single PSU cable is not recommended, which may trigger overheating risk. Please confirm your graphics card adopts 12+4pin 12VHPWR interface, this cable is NOT compatible with oldstyle 12pin GPU. Actual power capacity is subject to your powersupply rated output. Check PSU power rating before installation to avoid hardware damage
