What the numbers mean for you
Middle of the range
525 kSol/s sits between the Z15 and the Pro, at 4.73 J/kSol.
Price per kSol decides it
Today the Z15K costs — against — for the Pro. When that gap is wide, the Z15K wins on capital.
Best hosted at low rates
Because it draws more power per solution, the Z15K is most sensitive to your electricity rate. At our package rate it works; at a home tariff it rarely does.
Who the Z15K is for
A capital-efficient buy for people who have cheap power and a limited budget. You get most of the way to a Z15 Pro's hashrate for less money up front, and pay for it in electricity over time.
We confirm the wattage of the batch in stock on every quote. Use the calculator with the figure on your invoice.
Spot or batch?
Spot ships now at today's price. Batches ship in the month named and are usually cheaper; you reserve a batch by paying its invoice. Choose the batch in the hosting calculator above or in the order form.

Questions about the Z15K
Is the Z15K better than the Z15?
It hashes 25% faster but uses much more power, so it is less efficient per solution. Buy it when hosting rate is low and you want more hashrate per rack slot.
Is the Z15K better than the Z15 Pro?
No. The Pro delivers 60% more hashrate at better efficiency. The Z15K makes sense when its price per kSol is clearly lower on the day, or when Pro stock is short.
What power does the Z15K need?
A 200–240 V AC circuit. Budget for 2.5 kW continuous per unit.
