Connectors and I/O

Totally ASUS provided the Maximus IV Extreme with eight angled SATA ports which should be enough for any office PC or gaming system. You'll also find practical onboard power- and reset-buttons. ASUS even thought of a debug display which is very useful if you should once have issues with one of the components in your system. It is quite common that the last PCI-Express x16 slot is also the expansion slot the closest to the bottom edge of the board. That has the consequence that the connectors at this place aren't accessible anymore. With the Maximus IV Extreme, ASUS took this into account and placed the last PCI-Express x16 slot as the second last expansion slot and therefore there wont be any complications.

  

Totally you'll find eight fan headers on the ASUS Maximus IV Extreme which is more than enough, to provide a well equipped midrange or even a high-end-system with fresh air. The fanheaders are located around the CPU and their also spread over the whole board which makes them easily accessible from any position in an enclosure.

  

Looking at external connectors and buttons directly at the back-panel ASUS provided the Maximus IV Extreme with a PS2 mouse/keyboard connector, eight USB 3.0/2.0 ports, tow eSATA ports, two gigabit ethernet ports, a coaxial optical, an analogue audio panel as well as a Clr CMOS button and a RC Bluetooth switch.
