Onboard and Included Features
The I/O panel is always an interesting part of the motherboard as it dictates what connectivity options will be available. Starting at the left we have a single HDMI and Display Port connection. If you are using a K edition processor these will be active, next to that you will find three USB 2.0 ports. These are followed by four USB 3.2 Gen 1 ports with one being Type-C along with a single USB 3.2 Gen 2x2 Type-C variations. Network is handled by a single onboard 2.5Gb Ethernet and onboard WiFi 6E and Bluetooth.
The onboard audio found on the ROG Strix B660-I is pretty amazing and features the ROG SupremeFX 7.1-Channel High Definition Audio CODEC S1220A supporting High quality 120 dB SNR stereo playback output and 113 dB SNR recording input (Line-in). Premium audio capacitors help to maintain clean signals while a Savitech SV3H712 AMP handles the amplification.
One of the benefits to upgrading to a specialized motherboard is that not only do you get more features onboard but also in-box. The ASUS STRIX B660-I WiFi comes with a number of nice accessories including what you see below.
As expected, the included documentation is excellent and describes everything you will need to know when setting up this motherboard and the conditions required to make every component work.
