I think it’s not just in graphic cards but also in appliances in your home. There are reasons why there is specific specifications within device and there is always a power rating that it requires and you should follow and not overload it. I think you just follow the appropriate amount of graphic cards in a single PSU and you are good too.
The max usage of a power supply must not exceed 80% that means if you have an 800watt power supply you must use up to 640 watts only, this will prolong the life of the PSU, also use a watt meter to measure the exact power draw to be sure of what you are using.

I don’t see how it’s possible to hook up 10 GPUs to a 1000 watt PSU.
Maybe with a 1600Watt PSU it’s possible if you can rewrite some pins but most 1000 Watts won’t have 10 PCIe connectors to power all the GPUs. The max is like 4 or 6, maybe 8 on some with series split ends.
Most likely what happened here wasn’t the under powered PSU but some wire melted because he connected it in series. Very possible with those PCIe plugs with 2 connectors but one wire running back to the PSU.
You are wrong sir, I counted the graphic cards myself he used those 6 to 8 pin cable extenders and the motherboard are those builds that need no risers some called them riserless motherboards. PSU with just 6 Pcie 6pin plugs can be extended to 12 using 6pin (female) to 2x 8pin extender.

If you can spend thousands of dollars on GPU please always do the same for power supplies to avoid burning down your home, someone I knew put 10 GPUs on a 1000watt power supply and wires melted together which started a fire and did tremendous damage to his farm, the house was safe by the help of neighbours but not the rigs.
Do NOT MANAGE POWER SUPPLY, IF IS NOT ENOUGH TO DO THE JOB RUN FEW GPU's instead.

You are right, it is very important to really look at this issue because it's not just setting it up and you are good to go, you also have to look at the power and how it will not be overloaded because it is very dangerous. And in this example it causes a fire and then it burn and it cost huge money as well.
Or better yet, consult a license electrical engineer in your place to look and see how you can avoid overload.
And still worth to pay them good money, at least you will be safe and your business can continue.
that 1000% true if you guys plays on mining subforum that cause of fire its because chep PSU or electrical misconfiguration. so you better buys PSU with rating if you unsure with the rating you can always check https://www.clearesult.com/80plus/
Good PSU is expensive but it provide security and efficiency so still worth the money and u gonna use psu for long time period even more longer than GPU used for mining

I am pretty sure this is a common knowledge to everyone building their own Gaming PCs as well as building their own mining rig. Avoid every single generic power supplies also out there. I never built a mining rig, but back then I used a cheap PSU for my PC and the ATX cord to my motherboard just got fried and it was sparking. It was hell of an experience, but good thing I still manage to save my rig. I feared that my CPU was about to get crisped to death along with my Motherboard.
When I see a PSU with a ketchup-mustard cable, I sometimes assume that it is a bad PSU just coming from my experience.

I agree with @blockman if you are going to start a mining farm/rig you shouldn't be cheap with the components including the Power Supply Unit (PSU) just like what happened if you tried to save some bucks buying a PSU that is not capable of handling multiple powerful GPU it will only cost much problem in the future and cost a lot of money too.
It will really be a huge problem if you're trying to save a lot of money for your PSU and buys the cheaper ones. That's why even in PC setups, I'd try to be at the best with it and don't save from it because it's like the brain and heart of the system units that we use and the same goes for the mining rigs. There are situations that they've tried to save and eventually, as you've said, they encounter a heavier problem that has been costly to them due to the PSU of their choice.
Also, avoid fake power supplies from China, they are brandless and have cheap cable quality, I had one that killed my RX vega 56 two years ago, you can't cheap out on power supplies it's what keeps your GPU safe when working.

The power supply shouldn't be compromised if you own a mining farm/rig. It's actually one of the most delicate and important parts of the rig when you mine.
You shouldn't also be cheap spending with it because it can literally destroy all of the components of your mining rig. I'm not a miner but I've also seen a lot of miners telling the same thing about PSU.

If its true PSU overload the system will shut itself down but I'm guessing this person use a SATA cable to connect to the gpu? They easily start a fire that's why I said this, this cable is bad for powering a GPU.
I think the one that is responsible for that is the owner of the mining farm or rig since all of the miners know how to compute the power of the the GPU and what PSU they are going to use I always have 20%-30% allowance in my PSU to avoid things like this. I also think the miner didn't know what he is doing and probably need someone to help him next time to build a good, safe and efficient mining farm or rig.
