14. SSI power connectors (24-pin ATXPWR1, 8-pin ATX12V1, 4-pin ATX12V2)
These connectors are for SSI power supply plugs. The power supply plugs
are designed to t these connectors in only one orientation. Orient and rmly
push the connectors down until they completely t.
• For a fully congured system, we recommend that you use an SSI
12 V-compliant power supply unit (PSU) for LGA771-socket Intel
®
Xeon
Dual Core processors (Bensley platform).
• DO NOT forget to connect the 24+8+4-pin power plugs; otherwise, the
system will not boot up.
• Use of a PSU with a higher power output is recommended when conguring
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.
