I suspect your CPU bottlenecks your GPU. CPU seems at max and GPU is shown working at 4% load. Maybe that is why. RX 480 uses below 200w. My with RX 480 and i7 6700 only uses around 250 watts when gaming a heavy game. You should check your PSU too (see reviews).

That 8320 is power hungry cpu. Like I said, bottleneck is around 3%, so it's fine. As I mentioned 2 times, that psu is known to screw things up

Bottleneck is around 3% with that cpu+gpu so it's ok. PSU is weak-ish
There's something wrong, he says he even had the same problem with the nvidia 960. Compared to the 480 about power consumption it has 120w and nvidia recommends minimum 400w of psu. Not saying you're wrong, I believe you and he may possibly have bought a bad psu.
I wonder which version he got, can't be thermaltake london as it has golden +80 certificate.
If it's really the psu fault then this why you should search for information before buying, it's really important.
First psu and then the rest of the pc.

I ran some tests to try and see if it was the power supply causing the issue, as suggested above.

I ran FurMark's CPU burner for about 7 minutes. The usage was always at 100% and the temperatures hovered at 69 - 70 degrees Celsius. It never drew more than 40.16 watts of power, according to HWMonitor.

After that was over, I did the FurMark GPU stress test for about 7 minutes as well. The usage was always at 100% and the temperatures stayed between 75 and 78 degrees Celsius. It never drew more than 150.29 watts of power

I didn't disconnect anything during these tests since the CPU and GPU (the most power hungry things on the system) would not be simultaneously drawing a lot of power. During gaming that will obviously change but I did these as a test to see how much power is being used. The total then would add up to about 190 watts during game, assuming a 100% load on both the CPU and GPU (which never happens anyway, so this is the absolute maximum). I don't think power supply is the issue here.

If there's anything wrong with my tests or logic then please tell me.

On control panel and then power plan did you set the option to high performance?
Cpu temperature seems to be normal during gaming, It's a waste playing low settings and not using the full potential of the rx 480.

Yes it is set to high performance. temperatures are fine

Your CPU should draw way more than 40 watts. Closer to 125watts would be realistic
it seems like it's able to supply sufficient power to everything except the cpu. so this is a problem with the psu?

I don't get why people uses such a low wattage PSU, I understand that "yep" this will be enough moment, but why have just enough? Should always get more then what you need, this way the wattage will not be an issue later one down the road. Perhaps my definition of low wattage is different from everyone else, but 550W just seems too low to me. I'd try aiming for 1000w or more PSU, but that is me.

Perhaps the cpu is being starved of the needed power due to the GPU eating most of the power when it is working. Remember when the PSU approaches the maximum output, it get very unstable, so that 550W PSU is not guaranteed 550W output rating, it would probably be safe within 400 or maybe 450W range. Perhaps that is too generous, so I don't know. I cannot say for sure if it is the PSU, but it could very well be it.
Have you ever tried plugging your computer into a kill-a-watt meter? This should give you the total power consumption throughout the process.

That's not how it works, 1000w would be usefull if you sli/crossfire or build a workstation pc with 2 cpu's.
550w would be ok, you have to select a good brand and model version. Best thing searching for reviews or asking before buying.

Here i tried your building and it says load wattage 315W

I also did it including all of the usb devices connected and it says 371W at 100% load, and the recommended PSU is 421W. I did all of these calculations with the 960 before even building the PC.

I guess the best option according to people is to get a new PSU, then. I'm not getting a 1000w, that's outrageous.
Is this one any good? https://www.newegg.com/Product/Product.aspx?item=N82E16817139200

Is your GPU running on the Chill setting? AMD introduced a new setting in a recent-ish update. Probably not the cause but still

I doubt your PSU is the problem.

Of course not all 1000W PSU is created equal, I know that. You cannot damage your computer by having all those extra watts, where not having enough can be damaging. It not like the PSU constant draw be 1000W all the time, it will draw however much it needs to for a computer up to 1000W (maybe lower then that for safe operating ranges, but almost never at that marketed amount). I have 4 physical CPU in my computer and needs those high wattage PSU.
Also you shouldn't even think about even getting close to the rated wattage, as the PSU can not will get unstable even within the upper limits, even with the very well reputable brand.
