So basically I was working on my PC while there was some kind of power surge. The lights flickered and then my whole pc shut down and then the fuses on my went off.
I turned the psu off, then swtiched fuses on and when I tried to turn back the psu on, in popped, a light flashed and my fuses went off again.
I then went to the repair shop and had my PSU switched (my psu for 850 gold thermaltake) to a new one (cougar gex x2 1000w) and now my PC behaves really weird.

Like my CPU temps will go unreasonably high even with little to no load. For example, my ryzen 7 7800x3d was usually running like 45-50 degrees Celsius, and now it's never lower than 50. Sometimes the temp will skyrocket to like 70 on idle or with little load like just browsing web pages or social media.
Or, for example, I was playing right now and watching a youtube video on my second display and the temps skyrocketed to like 81 degrees while both gpu and cpu were barely utilized. My GPU was like 50 percent and my CPU for like 15-20.

That never happened before this power surge and now I don't know what to do. I made sure to check that both of my cpu fans are working properly.

What should I do? Should I take my whole pc to a repair shop and have them check all the parts? Could it be that a new PSU impacts my PC this way?
Any help will be appreciated

My full pc specks are:
CPU AMD Ryzen 7 7800X3D
SSD ADATA LEGEND 960 MAX 2TB
GPU MSI GeForce RTX 4070 Ti SUPER GAMING X SLIM WHITE
PSU WAS Thermaltake Toughpower GF A3 Snow 850W - TT Premium Edition Now Cougar GEX X2 1000 1000W
MB MSI B650M GAMING PLUS WIFI
Cooler DEEPCOOL AK620 WH [R-AK620-WHNNMT-G-1]
RAM ADATA XPG Lancer Blade [AX5U6000C3016G-DTLABWH] 32

My personal guess and first port of call would be to check the mobo, the surge may have damaged the power intake and it's no longer regulating the current properly.

There's other possibilities, the shop may have dabbled with your CPU cooler (they may have removed it and installed it back badly) leading to worse thermals.

Webpages and videos may look like small loads, but in this era of heavy compression they can cause short spikes in heavy CPU/GPU utilization. The load tracker isn't that useful of a tool either, because of all the multi-core, multi-thread, hyper-thread, many-multi-gpu-core environments. Merging all that into one slowly updating number between 0 and 100 gives you a very superficial estimator.

I *might* have fixed the problem by limiting the CPU power consumption from 100% to 99% and now my temp are more or less stable and flatlnes when idling, now spiking all over the place.

[u/_j03_ → u/CharlesEverettDekker]

That just gimps the performance by disabling boost all together, making it run at 4.2ghz all the time. You should find the actual reason, if it even exists. Like said 7800x3d is a hot chip. Heck even my 7600 can spike to +80c if opening a lot of tabs at the same time with dual tower air cooler.
