Chapter 2: Hardware information
8. ATX power connectors (24-pin EATXPWR1, 4-pin ATX12V1)
These connectors are for SSI 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.
• Use of an ATX 12 V Specification 2.0-compliant power supply unit (PSU)
that provides a minimum power of 450 W is recommended for a fully-
configured system.
• Do not forget to connect the 4-pin or 8-pin ATX +12 V power plug;
otherwise, the system will not boot up.
• 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.
• You must install a PSU with a higher power rating if you intend to install
additional devices.
