Use a comparable configuration
The Z15 Pro and Z15K sit in the Equihash category. For a useful comparison, put the Z15 Pro 840K beside the Z15K 565K rather than treating every Z15K rating as identical. The Z15K also has a 525K configuration with different figures.
Output and input, side by side
| Measure | Z15 Pro 840K | Z15K 565K |
|---|---|---|
| Rated output | 840 KSol/s | 565 KSol/s |
| Rated input | 2,780 W | 2,500 W |
| Efficiency | 3.31 J/KSol | 4.42 J/KSol |
| Input voltage | 200–240 V AC | 220–277 V AC |
The Pro adds 275 KSol/s of rated output for 280 W more rated input in this comparison. That is a hardware ratio, not a forecast of extra revenue.
Turn watts into an energy worksheet
At constant rated load, the Pro would use about 66.72 kWh over 24 hours. The 565K would use 60 kWh. Multiply those energy figures by your actual electricity rate, including applicable demand or delivery charges, to build a power-cost estimate.
The difference is 6.72 kWh per day per unit at these ratings. Actual consumption, uptime and conditions will vary; neither calculation establishes a financial return.
Do not stop at the circuit total
Both are air-cooled industrial miners. The Pro is listed at 75 dBA and the Z15K at approximately 75 dB. Both require a plan for heat, noise and the correct electrical installation. Neither is intended for a standard 120 V outlet.
Check the connectors, input rating and dedicated-circuit design for the exact unit with a licensed electrician. Aggregate wattage alone does not prove that a proposed fleet fits safely on your service.
Keep the purchase comparison separate
Ask for current quotes for the same quantity and destination, in the same currency, with condition and terms clearly specified. A more efficient hardware rating does not automatically make a unit the better purchase at every price.
Compare the Z15 Pro equipment profile with the Z15K configurations, then send the site details with your inquiry.
Specifications are catalog ratings and should be checked for the exact configuration. These notes do not promise mining income, equipment availability or a delivery date.
