Question about ASUS GeForce RTX 4060 DUAL OC EVO

And can we keep it outside the PC and have 2?

Hello,
Can I connect a second graphics card outside my PC?

To connect the graphics card, you need an 8-pin PCIe cable. This cable must be connected to a PCIe socket on your computer's power supply. Make sure your power supply has an 8-pin PCIe socket to supply the graphics card correctly.
