ASUS ROG Maximus Z790 Extreme Review

Operating Costs
With the cost of living increases across the world, especially when it comes to the cost of electricity, it’s worth looking at the cost of running a processor and how it compares to similar products on the market. By taking the average cost per kWh, we can calculate a rough running cost at idle, during a simulated workload test (Cinebench R23), to give us worst-case scenario costs, as well as gaming costs during a run of Cinebench R23.

Largely though, this motherboard is designed to be running hard rendering video or compiling a scene, and when its under load, the operating costs are actually pretty average.
