3. USB connector (10-1 pin USB45, USB7/8, USB9/10, USB11/12)
These connectors are for USB 2.0 ports. Connect the optional USB module cable to any of
these connectors and then install the module to a slot opening at the back of the system
chassis. These USB connectors comply with USB 2.0 specification that supports up to 480
Mbps connection speed.
4. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
These connectors are for ATX power supply plugs. The power supply plugs are designed to
fit these connectors in only one orientation. Find the proper orientation and push down
firmly until the connectors completely fit.
 Do not forget to connect the 4-pin ATX +12 V power plug;
otherwise, the system will not boot.
 Use of a PSU with a higher power output is recommended when
configuring a system with more power-consuming devices. The
system may become unstable or may not boot up if the power is
inadequate.
 Make sure that your power supply unit (PSU) can provide at
least the minimum power required by your system. See the
table below for details.
