8 GPU motherboard : how to boot it ?

[ico7liv2]

Hello,

I need your help. I bought this 8 GPU motherboard :
https://www.ebay.fr/itm/8GPU-DDR3-SATA-Mining-Motherboard-8xPCI-E-Extender-Riser-Card-For-For-BTC-ETH/153069705789?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649&autorefresh=true

I previously used a H81 pro btc, with a gold Enermax Power supply.

So :
I connected all 8pins in the smallest side of the big board

I connected the 6pins in front of the blue PCIe where the motherboard is plugged. I used the 8pins processor connector from the Enermax power supply for that.

I have to notice that the big 24pins ("MAIN" connector) from the power supply that goes usualy to the motherboard, can not be plugged in. So I don't understand how the motherboard could start when I power on the power supply...

look at this How do I run my ATX power supply without a motherboard?

Ok, thanks. I tried that already, but my power supply did a weird stuff. something like start/stop/start/stop in a second.
But maybe, i did not maintain a correct contact with the wire. I did not know that I have to keep the 2 pins together. I will try it again.

Does someone use this motherboard ? Is it the correct way to boot it ?
Doing my investigations, I read people use server power supplies, instead of classic PC power supply as I do.

And regarding the 6pins connectors all around the big card, should I plug them all ? (9 on the longest side, 8 on the small side)
Is a molex adapter (molex>6 pins) with only black (ground) and yellow (12v) wires (no red 5v) is ok ?
Same question with sata>6pins adapters ?

Thanks a lot

you shold plug all 6 pin  left side
all other output for vga

[blackline]

you must use 6 to 8 pin vga cable for do this
i tell you again you must plug power only left side 6 pin power
others for 6 pin output for plug vga power with 6 to 8 pin vga cable (if you use gtx 1060 6pin power then 6 to 6 pin vga cable)
