The question states that the computer is using an AT motherboard. This means that the power connection is provided by the P8 and P9 connectors from the power supply. These connectors typically each have 4 black wires for ground at one edge of the connector. When these connectors are installed properly, the black wires in each connector will be next to each other in the middle.
