Power Cable - AOpen MX64 User Manual

2.3 Connectors

2.3.1 Power Cable

The ATX power supply uses a 20-pin connector as shown below. Make sure
you plug in the cable in the right direction.
2.3.2 Fan
The CPU fan connectors are marked as CPUFAN1 and CPUFAN2 on the
system board. You can plug the CPU fan cable to both the 2-pin fan
connector CPUFAN2 and the 3-pin fan connector CPUFAN1. And FAN
connector can be used to connect housing fan. Note that only CPUFAN1 and
FAN support the fan monitoring function, because 3-pin fan has an extra pin
called SENSE, which periodically sends fan signal out.
Hardware Installation
Caution: Make sure that the power supply is
off before connecting or disconnecting the
power cable.
