it has 5 pcie cables that come from the unit.  they split into 7 cables.

and the unit has 8 gpus.

try and run  8 gpus with 5 cables = overload and melt downs.

no one should use the psu for the panda miner it should be used on a low load item  800 watts max that would be 160 watts for each of the 5 cables that may be okay
