Biostar Tb85 question.

[Vwgtiturbo1]

I put together my rig and started with 1 gpu and no issue thus far. Now for me to get power to my other 3 gpus on my mobo do I need to use the 2 molex plugs on the mobo? They read "auxpwr1" and "auxpwr2".. Now sure if I need to plug them to my psh to get my other gpus working. Thanks

You don't need to connect, I have been running 6 GPUs without any additional power to the motherboard.

Agreed, there should not be any need for the molex plugs on the motherboard. I have 2 of these TB85s with 6 GPUs and am not using those plugins (using powered risers for all GPUs of course).
