This is a beta version. You find it on Discord for example.

As a rule, whistling or hum can be emitted by inductors or chokes.

These elements make a sound during operation, but a person hears sounds with a frequency higher of 20 hertz. Read about it online.
If, under load of 90% of the power, the power supply produces stable voltages and there is no burning smell, then I would not worry much.

Mining throughout the years I made tons and tons of mistakes.

1) Keeping wallet.dat files for altcoins on the mining rigs. Ran into so many client wallets which had a virus on them.

2) Using SATA to power the GPU risers.

3) Keeping a motherboard sitting on the cardboard motherboard box, mining for weeks like that.

4) Putting an Antminer outside in the dead of winter. You would think this wouldn’t be an issue however they will crash and when they do, they won’t start mining again until you bring them inside to let thaw out.

5) Keeping a bunch of loud miners in my bedroom and then years later have difficulty sleeping without any fan noise. Need to keep a house fan on inside my room to fall asleep now. If it’s too silent I can’t fall asleep.

6) Instead of using reliable HDD/SSD being cheap and using USB sticks which die a few months later and need to reflash from scratch.

7) Being cheap and instead of getting a proper Network switch I just used old routers and had like 4-5 routers connected in series. Worked fine but tons and tons of CAT5 cable everywhere hanging.

First time using a air compressor to clean my fans. I set the compressor at the max PSI, and pointed at a fan to clean out the dust and it spun maybe at like 10000rpm and completely killed the fan bearing.

There are probably tons more. However these just come to memory.

Thanks for your response, the thing is those rx580 are for selling at 1660$ while the Nvidia 6 GPU 1660 are 1700$ the rx580 seems cheaper here since it's 7 pieces and more hashrate ready but high power consumption Vs those Nvidia, I've decided to go with the Nvidia cards anyway, thank you all.

I thought that server PSU is better than that desktop PC PSU even if they are rated at 80plus gold and others, I've watched some mining youtube videos and they always recommend those server PSU.

Greetings. Who can explain why, after adding 6700xt to the previously working RX478, on the air in Phoenix Miner 5.8c under Windows 10, driver 21.4.1, ping 45-70, Phoenix began pouring stales, (there are no stales on the statistics website 2MINERS.COM) I turn off 6700xt - everything is fine, there are no stales. I don't understand how a new card can do stales?

Whit the old hardware you have now the Windows 10 1709 and an old set of drivers, you should be fine, but for sure you can not found a set of drivers that will support AMD RX66xx cards. I think the Nvidia RTX3xxx series require Windows 10 20H1 or higher too.

Nice information on here, I don't even know that power supplies have premium ones that take less watt power from wall, all I know is better brands but the rating stuff is new, I have a question about 1200 watt power supply, is 1000watt load too much for a 1200watt PSU?.
