1.8 Power Supply

1.8.1 ATX Power Connectors: ATX1, PWR1
These ATX power connectors provide connections from power supply unit (PSU) to the mainboard.
Both connectors need to be installed in order for the mainboard to function properly. The power
supply plugs are designed to fit with these ATX power connectors in one orientation only. To connect
these power supply plugs; find the proper orientation first, and then push down the power supply
plugs firmly until the connectors are completely fit.
If you'd like to use the 20-pin ATX power supply, please align the 20-pin power connector from PSU
to pin 1 & pin 13 of "ATX1". There is also a foolproof design on pin 11, 12, 23, & 24 to avoid wrong
installation.
1. It is recommended that you use a power supply unit (PSU) that complies with ATX
12V specification 2.0 (or later version) and provides a minimum power of 500W. If
you are planning to fully load the slots and/or use a PCI-E x16 graphic card, a power
supply with minimum power of 600W or more might be needed.
2. Do not forget to connect the 4-pin "PWR" power plug; otherwise, the system will
not boot.
3. 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 if the power supply is inadequate.
