Calculate total power consumption of your mining rig. Sum GPUs, CPUs, fans, and motherboard to find the right PSU size and daily electricity cost.
Building a mining rig requires careful power planning. Under-sizing your PSU risks instability and shutdowns, while over-sizing wastes money. This calculator sums up the power draw of every component — GPUs, CPU, motherboard, fans, and peripherals — to give you an accurate total wattage and PSU recommendation.
Knowing your exact power draw is also essential for estimating electricity costs. Every watt counts when your equipment runs 24/7. This tool takes your component-level power numbers and calculates daily, monthly, and annual electricity costs at your rate.
The calculator also recommends a PSU size with a safety margin, ensuring your power supply runs efficiently and reliably under mining loads.
Crypto traders, long-term holders, and DeFi participants benefit from transparent mining rig wattage calculations when planning entries, exits, or portfolio rebalances. Revisit this calculator whenever market conditions shift to keep your strategy grounded in accurate data.
From swing traders timing short-term moves to HODLers tracking long-term gains, accurate mining rig wattage data is essential for disciplined portfolio management. Adjust the inputs above to mirror your actual holdings and market assumptions, then re-run the numbers whenever the landscape shifts.

Correctly sizing your power supply prevents crashes, extends equipment lifespan, and ensures efficient operation. PSUs operate most efficiently at 60-80% load. This calculator helps you choose the right PSU and accurately predict electricity costs. Real-time recalculation lets you model different market scenarios quickly, so you can act with confidence rather than relying on rough mental estimates.
Total Watts = (GPU Watts × Count) + CPU + Motherboard + Fans + Overhead Recommended PSU = Total Watts / 0.8 (80% efficiency target) Daily kWh = Total Watts × 24 / 1000 Monthly Cost = Daily kWh × 30 × Rate
Result: Total: 1,150W | PSU: 1,438W recommended | $82.80/month
Six GPUs at 170W (1,020W) plus CPU (65W), motherboard (40W), and fans (25W) total 1,150W. At 80% PSU efficiency target, you need at least a 1,438W PSU — a 1,500W or dual 850W setup. Running 24/7 at $0.10/kWh costs $2.76/day or $82.80/month.
Power planning is one of the most critical aspects of building a mining rig. An undersized PSU causes instability, while an oversized one wastes money. The sweet spot is a PSU running at 60-80% of its rated capacity.
Never exceed the capacity of your wall outlet or circuit breaker. A standard 15A/120V circuit supports about 1,800W. At 240V (if available), the same breaker supports twice as much. Dedicated circuits are recommended for mining.
Server PSUs with breakout boards offer the best watts-per-dollar for mining rigs. Combined with proper undervolting of GPUs, you can significantly reduce both total power draw and PSU requirements, saving on both hardware and electricity costs.
Always use measured watts from mining software or a kill-a-watt meter. Mining power draw is usually 20-40% lower than a GPU's TDP because mining workloads don't stress all GPU components equally, especially with undervolting.
80+ Gold is the minimum recommendation for mining. Platinum or Titanium rated PSUs reduce waste heat and electricity costs. Over a year, the efficiency savings can pay for the higher PSU cost.
Yes, dual PSU setups are common in mining. Use a dual PSU adapter or Y-splitter to sync both PSUs. This lets you power 8+ GPU rigs without needing a single expensive high-wattage PSU.
An under-sized PSU may shut down under load, causing mining downtime. It also runs at high temperatures, reducing lifespan. Even if it seems to work, running at 90%+ load continuously degrades the PSU faster.
Server PSUs (like HP 750W or 1200W units) are extremely efficient (Platinum rated), very affordable used, and reliable. They require breakout boards for PCIe connectors but are a popular cost-effective mining PSU solution.
In mining rigs, the CPU does minimal work, so even a 65W TDP CPU may draw only 15-30W. However, you still need to account for it. Use a low-power CPU (Celeron or similar) to minimize overhead.
