A quick Google search on that PSU didn't yield any results that would make me recommend that brand.
See here for starters;
https://cultists.network/140/psu-tier-list/
They rate it either Tier C - Low End or Tier F - Avoid.
The few review site I found also rated it very badly.
GSI event log is showing a process called Schannel constantly erroring, and with futuristic dates.
Finding out why or just disable logging, see here;

I'm not sure how important Schannel is but it seems to be related to SSL certificates and remote access.
Otherwise, finding the reason for FPS drops are the Holy Grail of gamers.
I’m not a gamer but here is my stock standard response, see if anything helps.
If you have your PC as lean and clean as you can make it, that's part of the battle.
Sadly, the other parts may be outside your control like; number of users/devices on your network, bandwidth, line attenuation, signal to noise ratio, etc. Logging into your modem's config menu will show these values.
But things you can control are;
- reboot modem/router/pc
- delete restore points
- turn off hibernation (powercfg -h off)
- empty web browser cache
- delete system temp files
- scan Windows for system corruption (sfc /scannow)
- scan drive for file corruption (chkdsk c: /r)
- disable unwanted scheduled tasks
- disable unnecessary startup services
- disable scheduled defragging
- TRIM any SSD's
- turn off Timeline and Activity History, and all things Microsoft Telemetry based
- empty recycle bin
- delete log files and error reports
- remove old Windows Updates files
- cleanup software installer and distribution caches
- delete unwanted programs
- remove any browser extensions
- if connecting via wireless, try ethernet
- pause any online cloud storage synchronising (OneDrive, DropBox)
CCleaner or
Glary Disk Cleaner or the inbuilt
cleanmgr command can do most of those points.
Note: when running CCleaner,
only run the Custom Clean, not the Health Check, or Registry clean, or Driver Updater features.
Also, when installing, be sure to check all pre-selected options carefully and not simply allow it to use default suggestions.
It may offer to install AVG Anti-virus, there is no need for this.
It will also add a Smart Cleaning process to Windows Startup and a couple of tasks to Task Scheduler – these can be disabled from within CCleaner.
ShutUp10 by O&O Software can stop a lot of telemetry items.
Other things to try; create another user account and login under that profile.
Also check for firmware updates for modem/router and PC BIOS.
