Hi I am wondering is it possible to connect the PCIe risers to PSU2 and also all the GPUs are connected to PSU2(around 4 GPUs), The main PSU1 just powers the mainboard right now, because the rig is around 90cm in length i started from PSU2 side and the cards are installed nearest PSU2.

So basically the PSU2 powers the PCIe risers and 8/6 pin connectors and all cards. I think maybe powering the PCIe risers from PSU1. And try to power the GPU 1-2-3-4 from PSU1 and the rest from PSU2.

All the risers are powered from PSU2 and the GPUs also.

The cards seem not to start. Only 1 card started.

PSU 1 and PSU2 are soldered on green and black and powers on together.
Please advice.

In windows device manager it shows only 1 card. And also in ccminer.

Rig has place for around 11 cards

Mobo: ASrock H110 Btc+
GPUs: Nvidia 1060-1070-1080

That is a serious Build you got there. If you think its a PSU issue do as you were stating unplug everyone of them. Slowly hook each one up at a time and boot up the PC each time to see if they start and if Windows will Recognize the GPU's. Keep doing it till you get a Failure. If you do then yeah it could very well be a PSU issue.

So for instance hook up Card#1 and boot it up see if it starts. Then see if windows sees it. Turn off pc
Hook up card#1 and #2 and repeat the process and continue the hook up process.
