POuW requires GPUs with good processors and ram with many lanes and usually 8x to 16x PCIe bus speeds.
It makes me wonder how things like dynex are real with all the GPUs are on 1x speeds.
The "POuW" stuff people actually pay for like on vast.ai are very expensive.
The administration of rental services recommends setting the stock settings for the video card and specifying the characteristics of the equipment. Not all tasks require 8x to 16x PCIe bus speeds. If you bought an expensive motherboard for this, then it will be a plus for renting out, but so far it is not profitable. In most cases, mining farms mine cryptocurrencies and are not rented for useful computing.
