Power Consumption
I use the Powenetics system to measure power consumption in every significant part of the mainboard, with up to 1000 readings per second.
Peak Power Consumption
I obtained the peak power consumption readings shown in the graph above during the start of the Prime95 benchmark. With Prime95 running for over 30 minutes, I noticed power spikes exceeding 400W!
Energy Usage
Besides power consumption, I also look at the energy usage of each CPU to see how efficient they are; by calculating the total amount of power required to finish two tasks, a Super Pi run indicative of single-threaded applications and a Cinebench run for multi-threaded scenarios.
In single-thread, energy usage is increased because the Z690 mainboard needs more energy than the B760 one.
Sorry, but those numbers cannot be correct. B760 has no OC, enforced power limits, thus 241W to the CPU for a max of 56 seconds.
That would explain the VRM and CPU temps, because with that VRM, that cooler, and 350+W into the CPU, the VRM and CPU temps would not be that low even on Mars.
I have powenetics measuring CPU power consumption in real-time, throughout all tests. In gaming, the PSU doesn’t have to go full power, while in apps the difference is 10%! So the numbers are correct, yes.
