Add2psu problems. Cant run the rig with 2 psu. Help pls.

[Vanila]

Hello everyone, im quite new in mining. i Have a rig on Asus z170 motherboard, intel i7 6700k (took it from my gaming pc as a motherboard). 4 videocards gtx 1070. 1 psu is  Corsair 750w and the second one is Be quite pure power 9 -600w.

The problem is that im running now on 750w 3x 1070. I bought a add2psu to synchronise both psus but, when i connect everything and run the rig- i have nothing on the monitor but the rig is actually working. I see black screen with white stripes in the top left corner as always and then it just turns to black.

Im sure that i connected everything as it must be- Main psu holds motherboard with 24pin and cpu, ssd drive, 2 risers and 2 cards in it, the third card is in the motherboard.

What i coud do wrong and how can i run my rig? Cause its rly frustrating after waiting 10 days for that add2psu and my 4-th card is still waiting for nothing...

Thanks for reading all this. Im not mothertangue so im sorry if i did any mistakes in what i wrote.

If your system is up and running, then I don't there is any problem with dual PSU setup.Try to use USB riser for all the cards and give it a go, make sure you have made necessary bios settings to run all four GPUs perfectly. Try it again and you'll get them working anyhow.

It has nothing to do with 2nd PSU.

Connect your display to the GPU that's in the topmost x16 PCIe slot.

Did you check integrated gpu signal? Are you using unpowered risers?

Hi guys, i got some results, you were wright, its not 2psu problem, i coud run the system with 3 cards. Something is with BIOS on the motherboard as someone said. What shoud i do with bios to make it work? I heard about restarting it by tooking off the battery. But then i need to setup the bios , any guide for how to do this? Thanks a lot.
