• Power Failure Recovery

When power returns after an AC power failure, you may choose to either power-on the system

manually or let the system power-on automatically.

• USB

The system board supports the new USB 3.0. It is capable of running at a maximum transmis-

sion speed of up to 5 Gbit/s (625 MB/s) and is faster than USB 2.0 (480 Mbit/s, or 60 MB/s)

and USB 1.1 (12Mb/s). USB 3.0 reduces the time required for data transmission, reduces

power consumption, and is backward compatible with USB 2.0. It is a marked improvement

in device transfer speeds between your computer and a wide range of simultaneously

accessible external Plug and Play peripherals.

Important:

The 5V_standby power source of your power supply must support ≥720mA.

• Wake-On-USB (optional)

This function allows you to use a USB keyboard or USB mouse to wake up a system from the

S3 (STR - Suspend To RAM) state.

• RTC Timer

The RTC installed on the system board allows your system to automatically power-on on the

set date and time.

• ACPI STR

The system board is designed to meet the ACPI (Advanced Configuration and Power Interface)

specification. ACPI has energy saving features that enables PCs to implement Power Manage-

ment and Plug-and-Play with operating systems that support OS Direct Power Management.

ACPI when enabled in the Power Management Setup will allow you to use the Suspend to RAM

function

With the Suspend to RAM function enabled, you can power-off the system at once by pressing

the power button or selecting “Standby” when you shut down Windows® without having to

go through the sometimes tiresome process of closing files, applications and operating system.

This is because the system is capable of storing all programs and data files during the entire

operating session into RAM (Random Access Memory) when it powers-off. The operating ses-

sion will resume exactly where you left off the next time you power-on the system.

Important:

If you are using the Wake-On-USB Keyboard/Mouse function for 2 USB ports, the

5V_standby power source of your power supply must support ≥1.5A. For 3 or more

USB ports, the 5V_standby power source of your power supply must support ≥2A.

• Wake-On-LAN

This feature allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. It is

supported via the onboard LAN port or via a PCIe LAN card that uses the PCIe PME (Power

Management Event) signal. However, if your system is in the Suspend mode, you can power-

on the system only through an IRQ or DMA interrupt.

Important:

The 5V_standby power source of your power supply must support ≥720mA.
