Power is fed to the processor through a 12+4 phase VRM design. ASUS uses what they call the DIGI+ VRM, which provides better precision and more control. Users can adjust load-line calibration for both the processor core and the integrated graphics portion, change VRM frequency and control the number of working phases through the BIOS.
Flipping the board over, we found that the underside of the VRM area is also cooled.
The back panel I/O has:
- a total of six USB 2.0 ports (black and red ones),
- two USB 3.0 (blue ones) controlled by a second ASMedia AS1042,
- three display outputs: analog, DVI and HDMI,
- analog audio connectors and optical out via Realtek ALC882,
- an eSATA port controlled by a JMicron JMB362, and
- Intel 82579 Gigabit Ethernet
Other features not mentioned earlier include Bluetooth 2.1 + EDR and LucidLogix Virtu.
LucidLogix Virtu is a software-based solution which dynamically assigns tasks to the appropriate graphics processors available. For example, when a game is detected, the discrete graphics will be called to take over fully. Upon returning to the desktop, the processor's integrated graphics will be used instead. The discrete graphics is put to idle mode to reduce heat and power consumption. When editing videos, Virtu makes it possible where supported formats will be handled by Intel's Quick Sync Video technology for unmatched encoding speeds.
