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 fit these connectors in only one orientation. Orient and firmly push the connectors down until they completely fit. • For a fully configured 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 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.
