The 14900KF processor found inside the Project Zero Infinity desktop is definitely on the ‘hungrier' side of the processors released in recent times. At idle the CPU package power usage sat around the 45 Watt mark. However, when carrying out a CPU based test like Cinebench, that usage soared to the processor's maximum turbo power limit of 253 Watts. When gaming in Cyberpunk 2077, the 14900KF used just under half of that Cinebench figure, sitting at roughly 122 Watts.
CPU package temperature mirrors the power usage figures from the previous chart, with the 14900K peaking at 92 degrees when running through a 10 minute Cinebench multicore benchmark. Things proved a little cooler when gaming, with the CPU hitting 72 degrees when playing Cyberpunk 2077. Finally, with the system idle, the Intel chip hovered around the 53 degree mark.
GPU temperatures, when measured after a 30 minute sustained gaming test in Cyberpunk 2077, were all fairly cool. The GPU sensor peaked at just 66 degrees, while the hotspot and memory sensors recorded 77 and 70 degrees, respectively.
The Project Zero Infinity uses fan curves set in the BIOS to manage thermals. These are fairly aggressive and do lead to some substantial fan noise, especially when running a Cinebench multicore benchmark.

Finally, overall system power usage, when measured at the wall socket, reveals just how power hungry the system is – topping out at a very lofty 542 Watts during a gaming test. Removing a lot of the GPU load from the scenario and running a Cinebench multicore benchmark sees this figure drop to 432 Watts, while the system draws just under 100W at idle.
