That is more like it. Unfortunately, you've probably picked the absolute worst time to start. There's a shortage of new gear, and with the rise in price and not much new gear coming online the profitability has gone up a lot and looks like it will stay that way until the miner manufacturers start delivering more or the price goes down. Eventually, the manufactures will manage to get some fab capacity and will dump as many miners as they possibly can, which will reset profitability again.

But right now, people see the price going up, and profitability really high, and are paying prices for gear based on thinking the price is going to go even higher.

With your power cost you could be profitable with an S9 even if the difficulty doubled. And even though the price of used S9s have nearly 10Xed in the last 6 months, (I think they are up to  $250 per miner with psu), you'd be able to make back your investment in 3 months if conditions remain the same.

So I'd look at S9s or Avalon miners in the 60 to 80 W/TH range. Maybe Canaan Avalon 1066 would work, those you can still buy new, and they have a reputation for being higher quality. With power that cheap I don't think it makes sense to pay a premium for super-efficient gear.

I am mining here in the UK I have 4 x small farms, running just under 10PH total now.

I don't use PDU's. I have 1 x 20A breaker for EACH miner, with 2 x iec C14 power cables wired directly into each breaker.

I use these extension cables and cut off the male end:

Happy to answer any questions if you PM me. I would say at £0.10 kw/h you'll struggle to profit though :/

Ok, that is not extremely cheap. These days you are competing against industrial miners that are paying closer to 0.02 GPB/kwh. They are the ones buying the most equipment, so they drive the miner prices based on their profitability.

First step is to just use an online profitability calculator (like this) to see what the #s look like for any given miner, and how long it will take to break even.
