Specifically designed for RTX 4090 and 4080 graphics cards, this ATX 3.0 12+4 pin power adapter converts four 8‑pin PCIe power cables into a single 12+4 pin connector. The 180° angled plug eases cable routing, reduces stress on the GPU power socket, and provides a clean, reliable power interface for next‑generation GPUs when used with ATX 3.0 power supplies that support 12+4 pin connections. Key benefits Power current-generation GPUs without replacing your PSU: lets RTX 4090 and 4080 cards be powered from an ATX 3.0 supply using four existing 8‑pin PCIe cables. Cleaner, safer cable routing: the 180° angled connector allows routing behind the motherboard tray or in tight spaces, reducing cable clutter and minimizing strain on the GPU socket. Simple retrofit/upgrade path: converts standard PCIe cables to the 12+4 pin GPU interface, simplifying system upgrades or retrofits. Reliable connection and durability: insulated wiring and secure, well‑fitting connectors help ensure stable power delivery to the graphics card. Key attributes Functionality: Converts 4 × 8‑pin PCIe power outputs into 1 × 12+4 pin ATX 3.0 GPU power connector for RTX 4090/4080. Compatibility: Intended for use with ATX 3.0 power supplies that provide 12+4 pin support and standard 8‑pin PCIe power cables. Size and design: Compact adapter with a 180° angled 12+4 pin plug for flexible installation in cramped or complex case layouts. Material and build: Insulated wiring and quality connectors for a reliable, secure interface between PSU cables and the GPU. Performance: Conforms to ATX 3.0 configuration requirements to support stable power delivery to compatible GPUs. Practical use scenarios Upgrading a PC: Use your existing 4 × 8‑pin PCIe cables from an ATX 3.0 PSU to power a newly installed RTX 4090 or 4080 without replacing the power supply. Small or tight cases: Route the angled connector behind the motherboard tray or into narrow cable channels to reduce visible cable bulk and improve airflow. System maintenance and modular builds: Create a clean, reconfigurable power layout that makes future GPU swaps or troubleshooting easier. Notes Use only with ATX 3.0 power supplies that support the 12+4 pin standard. Ensure all four 8‑pin PCIe cables are connected and secured to provide proper power distribution to the GPU.
