so ive been having this issue since my last pc which had a r5 3600 and a rtx 2080 super and 16gb ram all powered by a 650w psu. i got a totally new pc with a rtx 3080 r7 5800x and 32gb ram powered with 850w psu
full specs of new pc:
rtx 3080 msi gaming x trio stock settings latest driver(new)
r7 5800x stock settings(new)
32gb ram 3200mhz corsair vengeance rgb pro(new) xmp is on
b550 tomahawk(new)
2x HDD 1x 1tb WD caviar green(very old) and 1x 2tb seagate barracuda(from previous system)
2x ssd 1x nvme 250gb(from previous system) 970 evo plus samsung and 1x sata m.2 450gb kingston (os drive which is new)
windows 10 pro activated
GX850 PSU from seasonic 80+ gold
g7 odyssey 1440p 240hz monitor
things ive tried:
reinstalling drivers using ddu
reseating gpu and pcie cables of gpu
try another gpu (1080 Ti) still had the stuttering and gpu power drop but happened less due to it running at way lower frames than my 3080
tried another ram
removed all the hdd and ssd that were from my old computer which are the 970 evo plus and the 2 hard drives and installed a clean copy of windows on my brand new kingston m.2 sata drive
turning off xmp
tweaking windows settings
checking if any background apps are running
turning off instant replay
using old gpu driver
making sure temps are ok
tweaking nvidia control panel settings
turning off gsync
turning off one of my 2 monitors
i have tried everything software related i think the issue is beyond software, i have a suspicion its my surge protector or my power outlet because im not convinced that my corsair tx650m from my old system and my gx850 psu from my current system are faulty.
i did try limiting frames to no avail but even if it worked, why limit the frames i have the same right as someone else who owns the same specs and doesnt need to limit frames. i dont know it just makes me annoyed that this happens to me and me only.
any help would be greatly appreciated, i can come discord if someone wants it would be much easier and i could send screenshots/videos of anything you require to help me
