9.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.

Z97M-PLUS ATX power connectors

• For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12V Specification 2.3 (or later version) and provides a minimum power of 350 W.

• DO NOT forget to connect the 4-pin/8-pin EATX12V power plug. Otherwise, the system will not boot.

• We recommend that you use a PSU with a higher power output when configuring a system with more power-consuming devices. The system may become unstable or may not boot up if the power is inadequate.

• If you want to use two high-end PCI Express x16 cards, use a PSU with 1000W power or above to ensure the system stability.

• 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.

10. LPT connector (26-1 pin LPT)

The LPT (Line Printing Terminal) connector supports devices such as a printer. LPT standardizes as IEEE 1284, which is the parallel port interface on IBM PC-compatible computers.
