Short, direct adapter cable that converts four 8‑pin female GPU power inputs into a single 16‑pin PCB 5.0 (12+4Pin) 12V connector. Designed to deliver up to 600W and fit modern ‑end GPUs such as the RTX4090 and RTX4080. Key benefits Consolidates four 8‑pin GPU power plugs into one 16‑pin PCB 5.0 connector so you can use a single 16P power input on compatible systems and GPUs. 16AWG wiring supports current delivery for demanding GPUs (up to 600W per product specification). Compact 13CM length with 16P down bend orientation keeps routing tidy and supports clean cable management inside tight cases. What this cable does for you Solves compatibility and cable‑routing problems when adapting multiple 8‑pin GPU power leads to a PCB 5.0 12+4Pin 16‑pin input. Reduces clutter by consolidating four separate 8‑pin connections into a single, space‑efficient 16‑pin connection. Helps maintain a professional internal layout and proper connector orientation with the down bend 16P design. Key attributes Connector type: 4 x 8‑pin female (GPU side) to PCB 5.0 12+4Pin 16‑pin (12V). Wire gauge: 16AWG. Power rating: 600W (as specified). Length: 13CM. Orientation: 16P down bend for low‑profile routing. Compatibility: Suitable for RTX4090 and RTX4080 GPUs (matches the 16‑pin 12V input). Two practical use cases Upgrading to a GPU with a single 16‑pin 12V input: Use this adapter to combine existing 4×8‑pin power cables from your PSU into the single 16‑pin PCB 5.0 connector required by RTX4090/4080 class cards. Cable replacement or case rework: When reworking or downsizing a PC build, use the 13CM down‑bend adapter to route power cleanly behind the GPU and maintain a compact profile without running multiple separate cables. Notes and recommendations Verify your PSU can safely provide the required power for your GPU configuration before using the adapter. Ensure all connectors are fully seated and secured; follow GPU and PSU manufacturer guidelines for power connections. This product corresponds to the specification and features listed: 16AWG, 4×8Pin female to PCB 5.0 12+4Pin 12V 600W 16Pin, 13CM length, 16P down bend, suitable for RTX4090 and RTX4080.
