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).
