1.14.13ATX Power Connector (ATX1)

This connector is for an ATX Micro-Fit power supply. The plugs from the power sup- ply are designed to fit these connectors in only one orientation. Find the proper orien- tation and push down firmly until the connectors completely fit.

Important notes on the Motherboard Power Requirements

Note! ! Make sure that your ATX 12 V power supply can provide 6 A on the +12 V lead and at least 1A on the +5-volt standby lead (+5 VSB). The minimum recommended wattage is 180 W for a fully config- ured system. The system can become unstable and might experi- ence difficulty powering up if the power supply is inadequate.

!You must install a Power Supply with a higher power rating if you intend to install additional devices.
