2.10 – Installing the Power Supply
There are two power connectors on your Thunder K8SR.
The Thunder K8SR
requires
an EPS12V (24-pin + 8-pin) or ATX12V power
supply to boot. EPS12V power supplies are strongly recommended for dual CPU
configurations.
Please be aware that ATX 2.x and ATXGES power supplies are
not
compatible
with the board and can damage the motherboard and/or CPU(s).
Disconnect power supply from electrical outlet
Connect the EPS12V 8-pin power connector
Connect the EPS12V 24-pin power connector
Connect power cable to power supply to power outlet
Make sure you have connected both connectors before attempting to apply
power to the board.
