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=1I 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!

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!!

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.

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.

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

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.

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.

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.
