My rig is actualy mining again and i only reduced the power limit in HiveOs.
So the psu is working and i think i turned off the rig in time, when the situation was getting worse.
The 2000W psu is not overload now, but if i touch it in a specific side area, it is very hot, but only in that specific area of the right side, not entirely hot.
The psu fan is working too, because i feel the hot air coming out from the back of the psu.
This is the gpu list of my rig:

2X GeForce GTX 1080
1X Radeon RX 6600 XT
2X GeForce RTX 3060 Ti
3X GeForce RTX 3070 Ti
2X Radeon RX 6800 XT

Do you think if i buy 2 1200W psus, these will be adequate for a 12 gpus rig?
I will take another 2 gpus in few days.

wow, excellent rig!!

I'm not a mining expert, but as I have quite a bit of knowledge in this area, I'd like to share it with you

I performed some calculations on the consumption of your rig
(2) GTX 1080 = 360w
(1) RX 6600 xt = 160w
(2) RTX 3060 ti = 400w
(3) RTX 3070 ti = 870
(2) RX 6800 xt = 600W
TOTAL = 2390w <<< (gpus only)
Source: https://www.whatpsu.com/gpu

I don't know what the next gpus you will buy will be, I can't give you the exact consumption of your rig

I think it's interesting and valid, you buy a PSU of extreme quality, because your rig will consume a lot of energy.

I believe 2x Corsair AX 1500i (80 plus Titanium) will be a good choice. I believe these psus are expensive, but it will be a great purchase and it is also an excellent quality product.

I believe that there are members who have a much deeper knowledge than me in relation to mining, I think it's interesting that you also receive feedback from others users.

ps: these calculations I made are an ESTIMATE, it's not the EXACT consumption you will need.

I found this one that seems more interesting and is branded 'Cooler Master'.
It's a bit cheaper too and it has 50W more power:

@SamaritanMan, could you share with us the brand and model of your PSU? What vgas are you using for mining? (brand/model)

Have you tried reconnecting the power supply or your computer? It worked? Is it still smelling bad?
If practically NOTHING lit up, if the fans don't spin, you can be sure that your power supply is damaged... I believe that a capacitor or some component inside the power supply "exploded" and is not working.

The energy of your home is "pure"? Or does it fluctuate a lot? (in the sense of not flickering/oscillating)

If your home's energy fluctuates a lot, if you don't use a quality power strip and if your power supply is of low quality (no 80plus seal, no PFC), I have no doubt that this could compromise ALL your equipment.

I would like to share a advice, regarding the PSU, don't save, this is one of the main components of a computer, because depending on the situation, a poor quality PSU can compromise your entire computer.

From my experience, try to get a good quality PSU, with PFC and 80 PLUS seal, some brands I recommend are Corsair, EVGA, Cooler Master, Seasonic etc.

It seems perfect for my needs and the price is acceptable too.
Do you think it is a good bought?

Just buy 2 of these PSUs and your rig will be good to run.

the evga has six pcie slots

the be quiet has 4 pcie slots

I don't know what that means. The BeQuiet has 6 "PCIe connectors", probably using 4 cables ~~just like the EVGA does~~.
The EVGA has 8 8 pin GPU connectors on 6 cables.

Ok guys!
I had made a mistake in writing, because it was late.

I wanted to ask if it is better for me to keep my 2000W psu(if it's not damaged) and let it working toghether with a new one a have to buy, among the ones you adviced to buy.
So i will have a rig with 2 psus, the one i already have(2000W) and the new one i have to buy(maybe a 1000W Corsair).
Can these different psus work right together?
Or is it better to have 2 identical psus?

If the PSU was producing the smell it's probably damaged in addition to whatever other issues it has. Proceed with caution.
Don't cheap out and risk damaging your GPUs, better to get 2 new high quality PSUs. They don't need to be identical brands or sizes.

They don't need to be identical brands but don't mix and match their cables as the pinouts can be different and you could fry something.

Thank you everybody!
I try to buy it from Amazon, because i'm Prime and i don't pay any fee.
I'm from Italy
Do you think i can take the 2000W psu i already have and use it toghether with this new one i'm going to buy?
Or it's better to buy 2 of the same psu?

It was more profitable for me to buy 2 power supplies of 1000 watt CORSAIR RMX much cheaper than 1 power supply for 2000 watts. If you need a powerful power supply, then it is better to buy a used server power supply converted for mining. It's much cheaper. The server block is much noisier.

Does the psu's cooling fan return normally.

To test this, disconnect the power cables of the Gpu and half of the system from the system and run the system one at half power.

If you see that it is working normally in this case, check the oc settings of the GPUs. The gpu oc may not be running at the values you want, but at full power.

If Buddha is normal. Restart the system as a 10 gpu and observe it.Make sure that your power supply is at least 80% bronze.

Hi everybody,
i have a 10 gpus mining rig by 3 months and it is running 24/7 without any issues.
It has a 2000W power supply and it should be adequate according to the numbers of total wattage consumption, but today, i noticed a strage burning smell, so I immediately turned off the rig and the power supply was incredibly hot.
So i think if i hadn't been near the rig, everything would have burned out!
What do you think could have happened?
Do you think that the gpus could be damaged or only the power supply?

'The right to privacy matters'

if you are usa based look for this pair.

https://www.evga.com/products/product.aspx?pn=220-GP-1300-X1

1300 watts each for the evga and they will allow a constant 950-1050 watts each

https://www.bestbuy.com/site/corsair-rmx-series-rm1000x-80-plus-gold-fully-modular-atx-power-supply-black/6459246.p?skuId=6459246

these corsair will allow 800 watts each

Since you want to move to 12 cards I would look for the evga as they have more over head.

if you order direct from evga website here is a 10% code

Using Associate Code (VDN2319M4O569J4)

so 200 + 200 = 400 - 40 = 360 plus tax and free shipping.

pretty much should be what you need.

Note that code does not belong to me.

it is this guy's. https://forums.evga.com/Profile/4067763/ enewt

Oh thank you so much guys!
So do you thing i had better to completely stop mining untill i have 2 brand new quality psus?
While we're at it, could you recommend me directly a model for the 2 psus that I will have to buy?
I have a 10 gpus rig and i'm planning to add 2 more gpus in a while.
For now, i found another 750W psu and i move one of the 10 gpus(one of the most power hungry) to this one, so i reduced the power amount of about 200W from the big psu.
However, if i touch one side of the big psu, i can't keep my hand more than 2 seconds.
It is very hot, but not so hot as yesterday, when i felt a buring smell.
So i think i can go on with my mining and i'm only reduced the max power limit of the most consuming gpus.
Do you think i had better stop mining?
Thanks again!

yeah a 2000 watt atx psu can not do 2000 watts 24/7/365

my guess is you pushed the psu too hard. Most 2000 watt atx psu are shitty fake chinese crap.

even a really good expensive 1600 watt atx like the EVGA 1600g or 1600p or 1600t can do maybe 1300 watts 24/7/365 or 75-80%

a cheap 2000 watt chinese garbage atx will do around 1400 watts for a while. and 1000 watts for a long time.

let us know the make and model of your psu and how much power you did on it. I am giving thanks for your follow up in advance.

This is something that I've been sharing with people, do not use 100% or even 90% of total capacity
I think 80% is the sweet spot to use with safety and best efficiency of most gold rated PSUs
Buying a PSU with 5 or 10 years warranty and reading some reviews before buying is essential to be sure manufacturer is using reliable components
This is for ATXs PSUs

Another mistake to avoid is using too much adaptors, and specially the cheapest ones

And last but not least important, do not forget that all your GPUs can go to default settings at the same time with some driver error / overclock error and you'll have a peak of power

@SamaritanMan please share with us the model os PSU you were using, and your cable management

My cooling system in the power supply broke down, and then the transistors exploded. Transistors are mounted on aluminum heatsinks because they get very hot and need constant cooling. I replaced only the power supply and the mining farm started working. Maybe it's a coincidence, but the cougar's power supply worked a little longer than the warranty period

You can buy cheap risers and get away with it, you can buy cheap HDD, RAM and others but do not try it with a power supply, this is what will keep your GPUs in good shape while working and making money for you.
