Is this wattage fluctuation normal? My self built PC Win 10 Pro (built Dec 2018) is plugged into a Cyberpower 1500PFCLCD UPS. The wattage displayed by the UPS constantly goes up to 300ish watts and back down to 100ish watts even when I am looking at the desktop with nothing running except EVGA Precision XOC (default settings but fan curve altered for quieter operation). It even does this while in the Bios!
I spent days turning off as many of the unnecessary processes in Win 10 Pro as a user has access to. Especially the ones that reach back to MS, thousands of times a day. With the PC and monitor turned off, the wattage displays 30ish watts from the modem & router & switch plugged in. With the PC off but the monitor + modem + router + switch on, it displays 90ish watts and its steady. I turn the PC on the wattage starts bouncing from 100ish watts up to 300ish watts and back down to 100ish. It bounces non stop no matter what I am doing, even when left idle at desktop for hours. I don't use Geforce Experience and have blocked or disabled every single non essential thing that MS likes to force onto users, including the MS store app, Xbox app, and Windows update.
I am baffled as to why the PC would need to pull 200+ watts while sitting at the desktop doing nothing. I do have the 9900k set to auto for overclocking and it does sit around 5ghz on all cores even while doing nothing. In CPUID HW Monitor it shows the package only using 5 to 11 watts while idle (all core at 5Ghz). See attached Snip from HWMonitor. Intel C-state and other settings that reduce power when not needed are enabled. It appears they are working as intended according to HW Monitor. Do these power supplies constantly pull gulps of power due to some digital switching circuitry or is there something not working correctly?
In case its relevant, my PC has locked up multiple times with the annoying buzzing sound and complete inability to CTL ALT DEL (hard restart is required) when I start a league of legends game while also browsing in firefox or brave. The apparent solution to the crashing: Unplug my Seagate 6TB USB 3.0 backup drive. I assume that Riott Games is scanning all drives looking for the words cheat etc...and if the USB drive is currently not readable due to being idle for so long it causes the lockup? Not 100% sure that was the solution but the PC has not locked up in a few weeks now since I unplugged the USB drive.
