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

[JayDDee]

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.

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?

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

@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.

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.

[SamaritanMan]

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.

[OgNasty]

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

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.

Ok i bought this:

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.

[SamaritanMan]

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.

[SamaritanMan]

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.

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?

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.

[SamaritanMan]

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.

[verbakalim]

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.
