PCSpecialist Onyx Desktop Review (i5-14400F/4070)

Power consumption was measured at 30W when idle, rising to 59W when running a sustained Cinebench multicore benchmark and peaking at 125W during a 30 minute Cyberpunk 2077 gaming stress test.

CPU temperature was understandably highest during that same Cinebench benchmark, peaking at 67 degrees. Gaming saw the CPU reach 59 degrees, while idle temperatures were measures at 37 degrees Celsius.

GPU temperatures were recorded during a 30 minute gaming stress test using Cyberpunk 2077, running at maximum settings and 1440p resolution. The GPU reached a peak temperature of 70 degrees, whilst the Hotspot and Memory Junction readings were 83 and 76 degrees Celsius respectively.

Finally, system noise only changed marginally across our 3 different test scenarios. Reaching a peak of 40dB during a prolonged gaming test in Cyberpunk 2077.
