sigh You guys were all right. It is a power issue. I am a stubborn son of a bitch.
Thanks for making me see the light… I will be fixing this.

It’s hard to accept something when you’re frustrated and it can appear to be something it’s not. It’s all part of troubleshooting. I’m an extremely technical person but I still learn almost every day. Thanks for letting us know.

Use bminer you will get a higher hashrate with Equihash.
I used a 1000 watt EVGA Platinum for 4 1080’s at stock power levels and it turned off after 3 days so I assumed it was overloaded. It wouldn’t turn back on until it was unplugged for quite awhile. So I replaced it with a 1200 watt Corsair and it has been fine so far. I have a 850 watt Seasonic that wouldn’t even run 3 1080’s by itself. It also shut off after a couple of days. Both power supplies are running fine now with 1 less card on them. I also though have a 850 watt EVGA that is running 3 1080’s and a GS4400/Z270 setup. So some power supplies are either overrated or vary in the power they can put out.
The moral of the story is subtract at least 20% off the power rating of the power supply when comparing it to the TDP of the cards you are using for what you will be drawing off it for 24/7 usage.
Hi guys,
This was a really interesting convo. I actually need to get a few things confirmed. I have 6 EVGA 1070 and two EVGA 1070 ti in a rig. Currently the MB, the tis and one 1070 are powered by an EVGA 850 G2 (PSU1) and the other 5 1070s are powered by another EVGA 850 G2 (PSU2). The board is the Asus Prime Z270, Processor is Pentium G4400, memory is Corsair Vengeance and storage is Sandisk 240 SSD.
I had to RMA the 1070 on PSU1 and just got it back. So, with just the board and the tis I’ve measure that the PSU1 at 300w with my Kill a Watt and PSU2 at 540. On whattomine.com I’ve put my cards and they say Equihash will consume 960w, which I assume is just the GPUs.
I wanted to consolidate in one PSU and purchased an EVGA 1200w P2. Per this conversation, I would like to confirm that I probably will have crashes on peaks if I go through with this?
Thanks!
I don’t think 1200 will be enough. I think you would need a 1600 to put them all on one power supply. I am surprised you could run 5 1070’s with one 850 watt power supply and it not shut off after awhile.
Hey guys, the problem was fixed by powering the risers on a different rail on the PSU and driving the power limit down a few percentiles. My power meter shows a 1000 W draw, with all 6 cards mining wonderfully.
