Title: 6 GPU Mining Rig Restarts 6x RX 580 Gigabyte Post by: crypticj on May 08, 2017, 04:09:05 PM 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 https://preview.ibb.co/nvisgQ/20170508_105933.jpg (https://ibb.co/kiXUT5) best image uploading site (https://imgbb.com/) https://preview.ibb.co/hKUyMQ/20170508_105938.jpg (https://ibb.co/kQf51Q) best image uploading site (https://imgbb.com/) 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.

What is this type of psu? I do not know ... 1200w for $ 50?

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?

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? |
