Monoprice 12VHPWR 16-pin 90-degree adapter cable 5.9in Type A

Monoprice 12VHPWR 90° Type A adapter

This 12VHPWR 16-pin right-angle adapter connects a PCIe 5.0 power cable to compatible GeForce RTX 3090 Ti, 4070 Ti, 4080 and 4090 graphics cards. The Type A orientation routes the cable toward the backplate or cooler side depending on the specific model listed. It extends the connection by 5.9 inches using 16 AWG and 24 AWG tinned copper conductors rated for 600 W. The male-to-female design preserves the native 12+4 pin socket on the GPU.

Check GPU orientation before ordering

Verify that your exact card model appears in the Type A compatibility list, which includes specific AORUS Master, ASUS Strix and TUF, GIGABYTE Gaming OC and WINDFORCE, NVIDIA Founders Edition, and MSI Gaming X Trio, Suprim, Suprim Liquid X and Suprim X variants. The 90-degree bend direction is fixed; an incorrect orientation will prevent a secure fit or strain the connector. Ensure your power supply provides a native 12VHPWR or 12+4 pin source, as this adapter does not convert from older 8-pin connectors.

Thermals noise and power in normal use

The 16 AWG power conductors and alloy copper terminals are rated for 50 amps continuous current, supporting the full 600 W specification without excessive voltage drop. Tinned copper wiring resists oxidation, maintaining stable contact resistance over time. The short 5.9-inch length minimises resistive losses and keeps cable clutter low, aiding airflow around the GPU power input. No active cooling or moving parts are present, so the adapter adds zero acoustic noise to the system.
