• DO NOT forget to connect the 4-pin ATX +12 V power plug; otherwise, the system will
not boot.
• We recommend that you use a power supply unit (PSU) with a higher power output
when configuring a system with more power-consuming devices when you intend to
install additional devices. The system may become unstable or may not boot up if the
power is inadequate.
• Ensure that your PSU can provide at least the minimum power required by your system.
• If you intent to use a PSU with 20-pin and 4-pin power plugs, ensure that the 20-pin
power plug can provide at least 15A on +12V and that the PSU has a minimum power
rating of 350 W. The system may become unstable or may not boot up if the power is
inadequate.
10. Speaker connector (4- pin SPEAKER)
