Mining rig GPU hardware recommendations please?

[visten]

Hi,

So, I am trying to build a GPU mining rig.
I want to incooperate 3x 1060 6gb, 1x 1080 (and potentially more 1080s, 1070tis and/or 3x RX580s, this will mostly depend when they actually ship).

As the recommended mainboards are literally everywhere sold out. First, I cannot figure out which actually relatively normal priced mainboard is available for my needs as a beginner?

2.) I  also just cannot figure out or find a decently priced PSU or website that lists those which PSU I will actually need and how much the cards eventually consume? In this case at least the 3 1060s, 1x 1080 and let us assume rather 2 more RX580s OR two more 1070/1080?

Here, I am even thinking if it makes sense to buy one 1200W PSU if the ones with 850W etc. are just cheaper? What are the recommendations in those regards. I already check if they are platinium or gold certified.

3.) Are there are also any recommendations?

I am also only having a 15y old PC around with a Pentium 4, but the pci slots are the old ones (I did not kept up to date within the last years in regard to that, so I am still confused which PCI slots I need to use for graphic cards like the 1060 etc. when I am looking for other mainboards(that are not recommended anywhere)?)

I also would like to get the rig started as it could take some decent time until I get the "better" / recommended mainboards, the better PSU's etc. as I am not willing / it may make no sense to buy them overpriced at this point to me.

Are there any highly recommended websites with actual recommendations in regard to my questions? Please also consider that I need to order within Europe and usually I prefer Amazon.


Advice highly appreciated!!

Moreover, I am also confused in regard what is the difference between the digital and non-digital PSU's for example from Crosair or the HX and AX series from EVGA?
What seriously makes sense in terms of investment for a rather short-term investment of 1-2 years as those PSU differ so much in price....

Btw, Why is it also worse to use two PSU with for example two 750W (much cheaper) than one 1500W PSU? I still don't get that and also don't find a guide to figure that out.

4.) Which risers are actually recommended? What do I need to pay attention when I am ordering some? I always want to keep my costs low, but I don't even know what I need to pay attention to in detail when it comes to raisers?

Thx

This is the bitcoin mining section, you will never successfully mine Bitcoin with GPUs.

The altcoin section is here: https://bitcointalk.org/index.php?board=160.0


That said, if your computer is so old it has PCI and not PCIe slots, 1060 type GPU's won't work in it.
