Circuit Analysis Continued




A Qualcomm Killer e2201 gaming NIC is provided. Four of the USB 3.0 ports on the backpanel are routed through a NEC/Rensas D720210 which is a 1-to-4 USB 3.0 hub.




An IDT6V49332 is a clock generator which basically helps out with BCLK overclocking. The iTE IT8792E and at least six linear regulators are used to handle the extra pins in the socket; the CPU Mode switch is hooked up to this IC which digitally enables or disables extra pins.




Dual 128Mbit (16MB) BIOS ROMs are provided along with an IT8951E which allows for the addition of USB BIOS recovery in case DualBIOS doesn't work.




The main SuperIO is an IT8620E which monitors and controls voltage, temperature, and fans. It also provides the PS/2 keyboard and mouse ports on the back. A secondary EC is used, the IT8792E, and it helps the SuperIO. Four nuvoTon NCT3941S provide voltage mode fan control of four headers. Four NXP L04083B switch two PCI-E lanes each from the first PCI-E 16x slot to the second.




The RT8288A provides clean 5v power to the four USB DAC-UP ports which are yellow on the back panel. These ports have the ability to work without any power or with clean 5v power. Some USB DACs don't need USB power, just data, and with this system you can cut the power without cutting the data so it doesn't cause unneeded input noise.
