Hi guys,

Sorry if I am posting on the wrong section.

Below is my set up.

Asus Prime X370 Pro Motherboard - with the latest bios update
AMD A8-9600 processor
4GB Ram
3 x GTX 950
1 x GTX 1060
500W PSU x 2
Win 10 64 bit

I have not overclocked. The only changes I have done are to increase the fan speed.
I am able to mine with 2 GPUs. All my problems come when I try with 3 or more.
I am facing a few issues with my setup.

1. I am unable to get all 4 cards detected. I have confirmed that all risers and cards are working.
   I have changed the PCIE lane to 2x. Disabled on board audio in bios.
   Apart from these changes I believe that the mobo doesn't provide any more additional things to changes. Am I overlooking something?
   At max I am able to get only 3 GPUs detected. Is this because my CPU is an A8 instead of a Ryzen? Could it be blocking out some PCI lanes?

2. Even with 3 GPUs when I attempt to mine, my computer freezes, the screen blurs out and restarts. I have ensured that all the latest drivers are on the machine. Happens with nicehash and EWBF. (Those are the only 2 I tried). Can't be a heat issue or OC issue. Could it be due to the PSU? I have plugged in a second PSU when I am attempting with 3 or more GPUs.
I have one of those wattage meters plugged in and even when mining with 2 GPUs it shows around 240 watts usage. So I doubt that the PSU is unable to handle a 3rd GPU. But I have the 3rd and 4th plugged in to a second 500w PSU.

Any help is greatly appreciated.

Greetings sir
Have you already installed all the cards driver? If yes then increase the power / wattage of the supply.

You can move it (control at lower left) to technical support - you will get more help there.

Hi, do you mean to change the PSU or change power given to the GPU?
If it's to the GPU, may I know how it is to be done?

All GPU drivers are the latest.

Got it sorted out.
Plugged in one 850W PSU instead of the 2 500w PSU it things worked like a charm.
Although why it didn't work with the 2 PSU's I will never know.
