Intel 12400 consumes more power than 7700K during idle?
It's a reliable sign of the PSU performance. I've seen it increase based on workload several times before. Yes, the motherboard is definitely involved here. It's something I need to confirm. Where does the power disappear if the CPU uses 6W and the GPU 14W? Or could the CPU be drawing more than 6W, making Afterburner less effective? (I can't revert to my old system)
Contemporary? Absolutely. Performance? Limited. Intel makes these quite a bit more powerful under heavy load.
Did your room temperature or the case affect the situation? It seems a PSU fan considers both load and temperature. Just measuring power gives you the raw numbers. Idle mode is tricky—many tasks run even when nothing’s active. I’m not sure what you mean by newer Intel CPUs being more efficient. Their TDP values now don’t tell the whole story. My 7700k performs okay in normal use, but it spikes under load and my utility company charges more. I switched to AM5 because I prefer how Intel handles power on newer chips.
It's rated at 65W and all feedback highlights its efficiency. Yes, it worked well in my old system too. I'm sure your previous PSU fan would spin faster now, but I still believe what you're saying. I just switched to Windows 11, so load is minimal and nothing new was used. The Alder Lake really pushed past the 14nm limit, didn't it? Every review I've seen points out the lower power use and solid performance under full load. Updated June 7, 2023 by leclod
W11 adds many unnecessary features such as OneDrive. Turn off or remove startup for items you don’t need. Organizing W11 improved my boot time significantly. It seems that skipping these extras also lowers idle system demand. The updated chipset and memory might offer better performance. However, comparing power usage between systems isn’t reliable—just like claiming your car’s fuel efficiency based on infrequent trips.
The load is manageable and the CPU power consumption is expected to be low as well. MB remains an unknown factor—I’d rather fill it myself and cover 800km instead of 1000km. No need for further discussion. Edited June 7, 2023 by leclod
No argument about power consumption since you didn't provide power consumption numbers... it is possible that PSU has a stepped fan curve and just 1W or 1C difference pushed it to the 800 rpm step. Now being summer, you room may just be 2C warmer or so. If you didn't log temps, this is another missing data point. In idle, that new platform shouldn't be worse. But there shouldn't be much difference anyway.
It's a basic power supply with a straightforward DC fan regulator. The PSU heats up, causing the fan voltage to rise, likely due to a thermistor. Fan speed changes smoothly without jumps. No discrete steps observed. (Curious about my ability to track PSU fan speeds—I checked and found them predictable.) Edit: Another angle could be reduced airflow from the large aluminum heatsinks on the motherboard. Edited June 7, 2023 by leclod
