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?

Probably a bad quality psu or too small psu for your gpu setup.

Hard to say, because you did not mention any model info.

...aaand this is a altcoin mining rig. I asked mods to move it to the mining altcoins section.

Wrong section as this needs to be in the "Mining- Altcoins" section.

How did you work out you wattage spec? Did you allow for overhead?

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.

There seems to be a marketing trend for "mining PSUs" claiming 2kW.
There's no such thing as a mining PSU, and there are no 2kW PSUs for 120V.
You need 2 PSUs.

Hopefuly there was no colateral damage.

Next time try spending more dollars on power supply, as a miner you can't cheat power supply for mining, you spend thousands on graphic cards and you can't buy a corsair PSU or other top brand? Get serious mate.

There is always a first time for every new miner, I remember buying a Chinese 2000 watts PSU for my AMD mining rig, this power supply killed 2 GPUs on my watch, since that time I've learned to always stay away from the cheap power supply.

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.

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 :)

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

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!

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

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.

@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.

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?

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.

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.

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.

I found this on Amazon:

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

Use these…

https://www.parallelminer.com/product-category/open-air-mining/

the psu you linked is short on pcie cables

look for evga 1300 watt on italy amazon


https://www.amazon.it/EVGA-SuperNOVA-Modular-Warranty-220-GT-1300-X2/dp/B09JP7QPSV/ref=sr_1_1?

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.

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

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.

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:

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 was thinking the same thing.  Typically you want to leave 15% is what I always heard.  That would mean you wouldn't want to run more than 1700 watts on that PSU.  With 10 GPUs and likely a motherboard running on that, I can't imagine there wouldn't be problems.  Not to mention all the loss from what I can assume is a mess of cables.  I'd definitely get a new GPU going, and it wouldn't be a bad idea to think about replacing the single 2000 watt PSU with 2x 1300 watt PSUs to take some of the load off.  I'm not sure I'd risk hooking the burned PSU back up in any capacity.  You don't want to risk it damaging something else.

If you add the GPUs you plan to buy, these power supplies that you say you will buy will be enough for you. Since there will be 12 GPUs in total, make the distribution so that 6 GPUs are connected to each power supply. Also get from power supply multiplexers.

What do you think?
Thanks again for your great help guys!
:)

that is a good one.

it has six slots or jacks that will take pcie cables or cpu cables.

so 1 cable cpu goes in one slot or jack

and you can use five pcie cables for pcie

it will allow for 5 cables either single or double ended .

you can draw a steady 850-900 watts.

if you have two of them one can do the cpu and five cables for gpus
the other can do all six cables for gpus.

so you can run. 11 gpus each pulling about 150 watts or less.

I got a link for spare pcie cables I will look for it.


https://www.amazon.com/gp/product/B0979Y7F86/ref=ox_sc_act_title_1?smid=A2ZUCH4AFFNDHF&psc=1

they should be good for the hx1200

if i remember the psu will come with 2 cpu cables and 4 pcie cables

so you will need a few of these cables to fully use the psu’s

do you have a kill-a-watt-meter?


https://www.amazon.it/multifunzione-monitoraggio-apparecchiature-elettriche-sovraccarico/dp/B08V4RQZQL/ref=sr_1_16?

they help to know how you are drawing power.

the psu you purchased should stay under 900 watts on the meter for long term runs.

Are you running all these cards on a single motherboard? What type of motherboard you using? You need better air flow in your mining room or shed because those 3070ti generates high temp, should have bought 3070s instead, anyways two 1200watt will do well.

I have a Gigabyte H110-D3A mobo, but i'm using 2 pcie 1 to 4 splitters and i increased the pcie bandwidth to GEN3 in the bios, so i can use almost all the available pcie band for the splitters and so for the gpus.
I know i should get a new mobo for mining, with 12 pcie risers slot, so i can exploit all the power of my gpus.
If you can recommend me a good model to buy, would you give me another help.
Now i'm mining with a reduced gpus power limit, untill i install the new psus, so for now my hashrate has been decreased of about 150mh/s.
At full power, the hashrate of my rig, is at about 550mh/s, with the proper overclock settings for any gpu.
With the new gpus i plan to achive about 680mh/s, but the power consumption will be very high and i have already asked for a power increase of my elettrical system, from 3kw to 6kw, otherwise i wouldn't be able to live in my house anymore.
:D

Ok, my 2000W psu is dead!
Just during a reboot of my rig, anything turned off, but no strange smells.
Then i tried to temporary connect another psu to the mobo only and the system turned on, so it's surely the 2000W psu that stopped working.
Now i have to wait for the new psus to arrive, before restart my rig. :(
Do you think that some of the gpus may be damaged after this issue?
The model of my broken psu is:
"Crypto Mining Xpert 2000W" and it is Chinese because I see several writings with Chinese characters.

maybe your gpus are good. my fingers are crossed for you.

Thank you!
I think the issue has been such as a forced power off, because there wasn't any strange sounds or smells.
Moreover, the mobo is working, so i think there aren't other damages.
I hope i'm right.
But is there a chance all my gpus were killed forever?
Can i check the gpus one by one, connecting them in turn to the working power supply, just to check they power up?
If i see the gpu fans start rolling and the leds light up, does is it a good proof of work?
:o

To check video cards you need a working computer. Run furmark for 15 minutes at maximum settings and after the test you can be sure that the video card is working. Or better run mining on each video card for 15 minutes.

My rig is on HiveOs, so i go for the mining check.
So the gpus can also turn on, but then have problems while working?

If you are doing a video capt check, then you should not start all video cards at once. When I buy a used video card, I always test it on another computer before installing it in a mining farm. I install new video cards without checking.
If you have doubts about the performance of video cards, then it is better to spend a few hours checking them on another PC.

The burnt smell of the power supply warned you. You turned off the system before the system saw a bigger malfunction. I think that there are no problems with the remaining components of the system. When your new power supply arrives, you can control the system by running the GPUs one by one.

Thanks, but which is the differences if, at first glance, i try to start my rig as is and i check if all of my gpus mine whitout issues?
After this easy and straight check, if i notice some differences in the hashrate of some gpus, then and only then i go to deepen, only for that specific gpu.
What do you think?

Yes, i took just this one, because the first buy had a problem with the crypto card and so i looked better down the page and i noticed just that one.
Moreover it's 1300Watt.
Thanks however!

If any of the video cards is faulty, then you can get fireworks after turning on the mining farm. The motherboard for mining is more expensive, so I test video cards on a separate PC. If you think that all your video cards are working, then do as you please.

GPUs are powerful hardware products. These products do not deteriorate immediately. The routers you use to connect the GPUs to the system can cause problems. Therefore, enable each gpu one by one.

The first psu arrived and i spent some hours to assemble everything with only 5 gpus that work as ever, luckily.
Tomorrow the second psu will arrive and i will install the other 5 gpus.
Now i want to know approximately the power consumption of all the system in addition to the gpus, so the mobo, the risers, the ssd, the ram ecc..
So i can have an idea about the total power drain of my rig other than all the 10 gpus.
I took 2 of these:
https://www.amazon.it/gp/product/B09JP7QPSV/ref=ppx_yo_dt_b_asin_image_o01_s00?ie=UTF8&psc=1 (https://www.amazon.it/gp/product/B09JP7QPSV/ref=ppx_yo_dt_b_asin_image_o01_s00?ie=UTF8&psc=1)
I think these psus are perfect and now i have been able to arrange all the cables neatly and not tangled between the gpus.
I only have a doubt about the risers connections, because i used 3 molex connectors located along a single cable, but I have heard that it is better not to go beyond the two cable connectors per single cable.
Right?
However it's confusing because i found in the psu package, 2 molex cable with 4 connectors per cable.
Thanks again!

no no no no no no.

a molex can only do 1 riser safely
2 risers are a risk
3 riser = meltdown

Let me look at that psu a bit more closely

So you have 4 sata cables use one of these on 1 sata cable

https://www.amazon.com/Power-Cable-Adapter-Female-8-inch/dp/B07BQFKTG7/ref=sr_1_3?

so 3 of these packages are nine adapters  you have 2 psu's with 4 sata cables you can do all of those cables

so 4 sata to molex
2 molex    and first psu does 6 risers with 6 cables Should be safe

I stopped my rig as soon as i read your helpfull post!!
So do you mean i can use only 2 sata/molex cable i have per psu(so 4 in total) only for powering 2(so 4 total) gpus?
That is one cable per gpu, despite any sata/molex cable has 4 molex connectors?
So i should buy 3 of that sata to molex adapters, to use the other 3 sata connectors(6 in total with 2 psus) i have per psu, to adapt those cables for the risers molex connection?
Thanks for your quick salvation of my rig!!
:o

Sorry, but this whole rig story here is pure chaos.

Take it easy man, listen to the advices here and don't go with cheap supplies

I had a few components burnt since I started in 2018. Mostly the power cable from PSU to riser. Also the WIFI plug I use at the rigs. If you are able to identify the rig that has smell, check all the electrical components.

Of the mining equipment I have used over the years, the most problematic ones are cable sockets.
Receiving more than 2 terminals from the power supply sata cable.
The poor quality of the extension cords I use on the sata cable.
The poor quality of the socket of the multiplexers I use in Molex sockets.
Self-deteriorating rizers.

Yes man, i learned my lesson.

:|

Ok, i already have enough sata to molex adapters, because i recently bought, 2 packs of 6 risers that had these adapters included in the package.
So i changed my rig connections and now there are 1 molex cable per riser,  so 4 risers powered with molex and 6 risers powered with the 6 pin connectors.
The adapters i found in the risers packages are similar to the ones you linked, but they have the 6 pin connector on one end, instead of the molex one.
So i think they should be even better, right?
Now the rig is going perfectly and a big thank you goes out to all of you that supported me.
:)

Did you ever find out what was the source of smell?

likely he burnt a cap. they stink badly

Yes, i had overloaded my old chinese 2000W psu, powering 10 gpus all together with it.
After a month about, it was melting down.
:o

good that you found out. I have been very careful since I experienced burned smell myself a few occasion. I am a small miner so able to do smell test each day. The large miners probably have better solution. In my case it was electrical adapter and riser in separate occasions.

While the system is running, pay attention to the Gpu fans and check the connection sockets of the cables with your hand. It's usually cold. If heat has started in the cable socket, this will also cause problems. From the heat rate, you can notice this socket before it melts and solve it without problems. When the socket melts and the cables are damaged, you need to try a little harder. When the smell begins to come, the socket heats up and melts so much that it can no longer be saved.

If using Radeon RX 6600 XT and GeForce RTX 3060 Ti, then I would connect these 2 raisers from 1 single power branch, provided that the GeForce RTX 3060 Ti does not consume more than 140 watts. This is bad, but my farms have been working like this for 6 years, but I have high-quality wires and expensive PSUs. For such a number of video cards, it would probably be better to order a ready-made server block for 2 kilowatts for 200-250 dollars.

yeah I was extra cautious as a molex cable  can usually handle 2 lesser power cards. A sata cable not so much

he did get a very good set of power supplies in the 1300 watt EVGA's with enough cables to do his setup safely.

Thanks!
Another gpu is about to arrive and it is a Radeon 6700 XT that has 2 power connectors: 1 8-pin and 1 6-pin.
On my 2 psus, i already used most of the power connectors dedicated to the gpus, but there are other 2 6-pin connectors labeled as "Perif1", "Perif2" and another 8-pin connector labeled as "CPU2".
I wish to know if i can safely use these connectors to power the new 6700 XT, that is the CPU2(8-pin) and one of the 2 PerifX(6-pin) connectors.
Thanks again.

this will work , but be sure you check that it wired correctly.

i test it with a meter.

it will do about 175 watts safely maybe 200 your new card should be okay with it.

Yes i already have 12 of these splitters, so do you mean i can use 1 splitter to connect my 6700 XT to the 8-pin CPU2 connector of one of my psus?
And one of the two 6-pin connectors(labeled as Perif1 and Perif2) to power the riser?

yes all from same psu . but make absolutely sure that you have a cpu to pcie splitter.

if you use the cpu jack on the psu and the cpu cable to the proper splitter it works.

I have one splitter coming to my house today.

it must be  cpu to 2 pcie

not pcie to. 2 pcie

give me about an hour i can check if mine came in today.

But in general, the 8-pin splitters(1 female to 2 males) shouldn't overload the single 8-pin source connector?
If a gpu needs one 8-pin and one 6-pin plugs to be powered, doesn't need more power than a single 8-pin source plug can manage?
So is it safe to use these splitters?

assume he has the right one
assuming it was wired correctly and not defective
a cpu cable should be able to do 225 watts max
spilt it into 2 pcie plugs
have a third cable feed the riser. even a dedicated sata doing only 1 riser.

you should be able to do 175  24/7/365 on the  cpu/pcie adapter
and 50 24/7/365 on the sata to the riser.

or 175+50=225 24/7/365

he said he is doing a 6700 to a 6700xt. if he sets the power correctly it pulls under 175

he should be good

if he wired a nvidia 3090 fuck no he will melt shit.

The CPU to PCIE power adapters just arrived and they work perfectly.
First, i plugged the psu bundle cpu power cable, to the psu itself and then i plugged these new cpu to pcie adapters, to the previous one and they fit perfectly.
So any cpu connector of my psus, gives me 2 8-pin pcie connectors to power a gpu with 2 8-pin power connectors such as my new 6700 XT.
To power the risers too, i have to use another cpu to pcie adapter, using the 6-pin part of another cpu to pcie adapter cable, plugged to another cpu bundle power cable.
Now i buy other 2 more, so i can use all of my psus cpu power connectors, to power the last 12th gpu that is about to arrive.
Thanks!
