Rainy Day

I’ve seen some folks argue that efficiency is overrated if you have access to cheap electricity. I get the math, but I’m curious about real experiences. If your power cost is very low, does it actually make more sense to buy the cheapest rigs that throw out the highest TH/s, even if they’re less efficient? Or do the long-term maintenance and cooling costs still make that strategy risky?

I can share what I’ve seen in practice because a colleague of mine runs a facility in a region where electricity is just $0.05/kWh, and their strategy is all about raw output. They went heavy on machines like AxionMiner with 800 TH/s/12 kW and even older models that push 500 TH/s but at worse efficiency. The reasoning is simple: at that power rate, the electricity bill barely dents profitability, so buying the biggest possible rigs per dollar makes the most sense. A comparison chart I read made the same point: the 800 TH/s model at $6k wins on ROI when power is cheap, while the 11 W/TH models only show real advantage if rates are above $0.10/kWh. That article labeled the 860 TH/s Bitmain S21e XP Hyd 3U as the sheer output monster, but the price tag at $17k meant ROI is slower unless you can stack rigs cheaply. If you’re shopping in a market with abundant cheap power, going for a high hashrate bitcoin miner is definitely the play, but you need to prepare for the noise and cooling—those 12 kW units dump insane amounts of heat and sound like industrial fans. My advice is ducting directly outdoors, or your workspace will be unbearable.
