Just got into this mining thing with NiceHash on my daily driver computer and really enjoy it. I am planning to build a rig with spare parts I have laying around, one of which is this motherboard:

https://www.newegg.com/Product/Product.aspx?Item=N82E16813157477

I plan on building an open air rig with risers and will get my GPUs whenever/wherever I can as they become available at a decent price.

1. How many GPUs can I comfortably run off this mobo with the A10-7890K CPU I already have in it?
2. Which riser cards/cables are ideal?
3. Is 80% PSU ratio the sweet spot or should I look for a bit more extra power?

You can run max 4 on that mobo. You will need risers to run more than 2.

PSU ratio depends on the specific PSU, as some do better at higher wattages and some lower wattages for best efficiency. We'd need the specific model to have an idea, but generally around 80 is a good spot. Going near max is ok as most PSUs are 80+ certified and will stay above that for the most part.

Thats what I was thinking, thanks for the verification.

Any GPU I use will be 80+ Gold rated or better.

EDIT: (to add) I don't have the GPU yet, I will use EVGA, Corsair, Thermaltake, Seasonic etc at the above rating. Just what ever I find at the best deal when I buy. Just wanted to make sure that 80% usage was a good place to be for this.
