If your psu is modular, don't forget to unplug and check the socket that connects to the psu.
Using 1 cable for a 3090 might burn the connector to the psu, that's the cons of modular psu, a socket connection has a more probabilty to fuck up..good quantity of pcie cables start with 1000w and above. Personally, my minimum watts for psu is 1200w.

I have 4 PCIe connectors on the PSU.
Each cable splits to 2 8 Pins.
I have 2 cables (4 x 8 Pin) to the EVGA 3090.
3 of them are in the card and one powers the riser.
I have 1 cable (2 x 8 Pin) to the Zotac 3090.
They are both in the card.
I run a Molex for the riser.
That‘s pretty hefty, I know.
Almost 70 watts from the molex and 230 watts from a single 8 Pin to the PSU.
The Zotac 3070 sits right on the board with the last 8 Pin cable and has got the 2 x 8 Pin in the card
Did you decide to do this yourself or did another miner give you advice?Each cable splits to 2 8 Pins.

You need to connect 2 RTX 3090 video cards and raisers (6 pins) to your 850 w power supply, and for the motherboard and RTX 3070 it is enough to use a 600 watt power supply and for this video card you can use a molex raiser (although it is better to use a 6 pin raiser)
Here is the solution to your problem.
Yes, I already ordered a Seasonic Prime TX 1000.
I will run both PSUs together so even if all cards go to stock I will not have any problems.
But the availbility is very bad and it will be shipped in 2 weeks from now.

The psu is weak for that setup.
Spare psu can easily eliminate the doubt.

Very interesting after crash rig shouldnt consuming so high power like 700watts. it will consume some power but after 5-10min later should go down. Can you try another miner?
If psu cant handle it will just turn off, in your case it is not turning off it just continues consuming power.

Today it was gone again, but this time it restarted and was only consuming the 50w idle.
I guess a card crashed, restarted and was taking 100% PL and shut off the PSU.

I was not too lazy and counted the number of 8 pin connectors for connecting these three video cards. I counted 7 8 pin connectors.
I also don't understand which raisers are used and how they are connected.
For RTS 3090 6 pin raisers should be used. For such a mining farm, I would use a server power supply with the required number of connectors.

I run the following cards:
Zotac RTX 3090 Trinity @ +1150 Mem, 302W, 121 MH/s - on a riser
EVGA RTX 3090 Kingpin @ +1000 Mem, -200 Core, 285W, 119 MH/s - on a riser
Zotac RTX 3070 Twin Edge @ +1200 Mem, -100 Core, 130W, 61 MH/s - on a x16 Board Slot
In total that’s only 717 watts on 12V. The PSU is rated to 840 on 12V.
The rest of the system is about 50 watts.
So about 767 watts in total. 840 watts atw.
As soon as I lower the power limits the cards will not run stable or drop by 15 MH/s if I reduce 1% PL.

Check your risers and riser cables
Good point, but what should cause the mentioned problems?
Maybe I really need a monitor so I can see what the system looks like after crashing.
At the moment I can not connect, so I won‘t see what‘s going on.

recently i have a two or three failed risers on separate rigs, different timeframe.
sometimes the card(with riser problem) is not hot to touch unlike the other cards in the rig....sometimes cards with different light color when idle and running shows where the card with issue is..
on the mining pool i have a view of the number of workers, if the number of workers goes down i check what rig it is. if it is a reoccurring or suspicious to me if there is a problem, i remote view for 24/7 that specific rig so i can catch whatever is the issue.---note: this is on a separate monitor-not my main monitor.
tip: you can jam pack your pool monitor/ surveillance / remote view in a single monitor by window-sizing, putting one on top of the other (get creative).
That psu can not do 840 watts 24/7/365
It freezes the system nuff said.
Now 1st question is what are several 30xx cards?
is it 3x 3090 cards
is it 3x 3080 cards
is it 4x 3070 cards
is it 4x 3060ti cards
is it 4x 3060 cards
I do not know if you simple have great clocks but 1 card to many or
I can tell you right here right now windows drops power settings goes to TDP and it does it at random.
Been doing it since 2012 when I mined btc with amd 5770
does it with nvidia
does it with amd.
So to help you
tell us all your gpus
tell us your clocks
we can figure if you are clocked perfectly fine but have an extra card and the psu turns off due to thermals.
or we can figure if you are getting runaway tdp on 1 or more cards and the psu turns off due to thermals
I wish I had money for every over taxed system I read about on all the posts I have read I would be rich.
No ATX runs 24/7/365 at 840 of 850 for a long time.

And you spend more than $ 500 on a new power supply unit without knowing that it will help.
I wanted to build an other system and needed it anyways.
But it has 3 weeks delivery time
Check your risers and riser cables
Good point, but what should cause the mentioned problems?
This happens if you have to much OC, the driver do a reset and that is the reason why you can´t connect to the system via teamviewer.
Why?
I can‘t even connect. It‘s not like I get a black screen.

I guess it has something to do with Windows or the miner freezes.
That would explain why there is still a lot of power draw and why there is no internet connection or why I can not connect with Teamviewer.
I already ordered a Seasonic Prime TX 1000.
Let‘s see if the system is more stable with more power.
I don't understand your logic. You can turn off 1 video card and check the performance of the mining farm with less electricity consumption. If this helps, then of course it is worth buying a more powerful power supply unit or a second power supply unit for 500-600 watts + a synchronizer for starting power supplies.That would explain why there is still a lot of power draw and why there is no internet connection or why I can not connect with Teamviewer.

"Several" 30xx GPUs means ? 6 ? on a 850 Watt power supply?
I would go for more than 1000 Watt, even when you dont need it always.
If possible go for a 1200 / 1250 Watt.
Stay in using less than 80%.

When I changed to HiveOS, all my problems were solved, no more freezes or crashes
Windows 10 updates are horrible and there's always something to fix, and even if you stop the updates, the system continue to update after some time
But try HiveOS, it's simple, you can burn on a flashstick or in an small SSD, in a few minutes you're mining, and after the config, your system can run stable
