Hey Guys,

I see if we can collective solve the issue that I am having.
Rig Specs
1 600W Thermaltek PSU for MOBO and 1 GPU
1 1200 HP DPS 1200FB 94% platinum powersupply with 6-xrev Adapter 8 6pin to 6+2(pin) cables.
1 Gigabyte 990FXA UD3 REv5
1 Sempron Processor
6x RX580 4gb gigabyte

Here is the issue 1 gpu works fine with thermaltake and I stress tested it for 24 hours. When I plug in other 5 [I have tried doing 1 at a time checked risers cables etc] the miner restarts.

so as soon as i switch to 2 GPU [1 on thermaltake and 1 on 1200W PSU] the system restarts as soon as miner starts.
Let me know your thoughts
could it be related to GPU not getting enough power from the HP 1200w psu?


Thank you.

A lot of those HP PSU's won't do 1200W on 110v, they need higher voltage circuits, so they top out at 900W. With 5 x 580's on there with no undervolting you might be maxing out that HP PSU if it's plugged into a normal wall socket. It's just a guess!

Thanks I tried 1 RX 580 plugged into the PSU and even that restarts the system when miner starts?

Ah, so not a load issue.  Hmmm, not sure, I'll reply if any other ideas pop into my mind.

Thanks thats what I figured its not a load issue however the Board has 8 6pin to 6+2 Pin connector could it be that 1200w / 8 = 150w per connector is not enough  (to power RX 580) even when you plug in just 1?
