Internal connectors

1. ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)
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.
VANGUARD B85 ATX power connectors
• We recommend that you use an ATX 12V Specification 2.0-compliant power supply
unit (PSU) with a minimum of 300W power rating. This PSU type has 24-pin and 4-pin
power plugs.
• DO NOT forget to connect the 4-pin/8-pin ATX +12V power plug. Otherwise, the
system will not boot up.
• We recommend that you use a PSU with higher power output when configuring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
• If you are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at http://support.asus.
com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details.
2. Digital audio connector (4-1 pin SPDIF_OUT)
This connector is for an additional Sony/Philips Digital Interface (S/PDIF) port. Connect
the S/PDIF Out module cable to this connector, then install the module to a slot
opening at the back of the system chassis.
