ASUS CROSSHAIR V FORMULA-Z 1-43
Chapter 1
• For a fully configured system, we recommend that you use a power supply unit
(PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a
minimum power of 350 W.
• Do not forget to connect the 4-pin/8-pin EATX12 V power plug. Otherwise, the system
will not boot.
• Connect the 4-pin EZ_PLUG power plugs to ensure sufficient power supply when you
install multiple graphics cards.
• 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 or more 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.

(24-pin EATXPWR; 8-pin EATX12V_1; 4-pin EATX12V_2; 4-pin EZ_PLUG)
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
