Question about ASUS TUF RTX 5070 O12G GAMING

So, do I also have to pay attention if I want to install a new power supply?

The "TUF RTX 5070 O12G GAMING (12 GB)" graphics card is equipped with a PCI Express 5.0 connection. This interface is generally compatible with modern motherboards, including the Intel B660 series. However, you should make sure that your motherboard supports the PCI Express 5.0 slot and can provide enough power, as the graphics card has a recommended power supply of 750 watts. If your motherboard fulfils these requirements, the graphics card should work without any problems.
