SSI power connectors (24-pin ATXPWR1, 8-pin ATX12V1) SSI power connectors (24-pin ATXPWR1, 8-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 SSI 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. By default, four ATX12V1 connector pins are covered to prevent incorrent insertion of a 4-pin ATX +12V power plug. Remove this cover when using a PSU with an 8-pin ATX +12V power plug. Do not forget to connect the 4-pin or 8-pin ATX +12 V power plug; 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.
