Power Cable Connectors - Acer Aspire E650 Service Manual

Power Cable Connectors

Please note that the 20-pin and 24-pin power cables can both be connected to the ATX1 connector.
With the 20-pin power cable, just align the 20-pin power cable with the pin one of the ATX1
connector. However, using 20-pin power cable may make the system unbootable or unstable
because of insufficient electricity. A minimum power of 300W is recommended for a fully-configured
system.
