^^^^ Image of problem

The first image shows the system at idle, while the second image shows it under load. I am concerned after seeing the Power Reporting Deviation being at 113% under load.

So is it considered normal?

Yes.

I don’t understand why mine would be at 113% under load shouldn’t it be near 100%?

As said in the explanation:

Ryzen CPUs for AM4 platform rely on external, motherboard sourced telemetry to determine their power consumption.

The displayed figure is a percentage, with 100.0% being the completely unbiased baseline. When the motherboard manufacturer has both properly calibrated and declared the reference value, the reported figure should be pretty close to 100% under a stable, near-full-load scenario.

Obviously, the figure can be greater than 100%, but for the obvious reasons it rarely is.

So, most likely, the reference value isn't properly calibrated by the MoBo manufacturer (MSI).

If it is 100% or more, it's good. But if it is less than 100% on near-full load on CPU, e.g 75% or 50%, then there are some shenanigans by MoBo manufacturer going on.
Also, your value goes as high as 360.5%, so, the calibration of reference value is way off.

I understand the high values at idle are meaningless but will the motherboard telling the processor it is consuming more power then it really is cause performance issues

Yes.

So the board is completely fine? I understand that high values at idle are meaningless, but will the motherboard telling the processor it is consuming more power than it actually is cause performance issues?

 

[Aeacus]

but will the motherboard telling the processor it is consuming more power than it actually is cause performance issues?

113% offset just means that CPU thinks it is consuming more power than it actually is, thus it may limit the CPU to boost to higher clocks.

Your CPU has 3.7 Ghz base clocks and up to 4.6 Ghz boost clocks. If you bench your CPU, does it boost to 4.6 Ghz?
If it does, all is good and the 113% offset doesn't affect the performance.
But when CPU boosts up to 4.5 Ghz or so (less than 4.6 Ghz), then this can limit performance since MoBo tells CPU that it is consuming more power than it actually is, thus, CPU limits itself (because CPU thinks there's not enough headroom for high boost clocks).

Then again, boost clock 4.6 Ghz is "up to" and not fixed. So, when CPU boosts anything above 3.7 Ghz base - this is considered as normal operation.

Edit: Just checked and your CPU boosts to 4.45 Ghz. So, this would still be normal.

It boost to 4.4 when I start cinebench with pbo disabled then it stays around 4.14 but the base on the 5600 is 3.5 and boost 4.4

 

[Aeacus]

Which CPU you have? Since i see two different CPUs mentioned;

but the base on the 5600 is 3.5 and boost 4.4

Specs:
5600x

Yes, for R5 5600, the base is 3.5 Ghz and boost up to 4.4 Ghz.
But for R5 5600X, the base is 3.7 Ghz and boost up to 4.6 Ghz.

Mb I meant 5600

Then, base and boost clocks are normal and nothing to worry about.

On cinebench r23 after enabling pbo it stays around 4.3-4.35 is that about what it should be at?

 

[Aeacus]

after enabling pbo it stays around 4.3-4.35

Well, PBO gives CPU more boost overhead if there is overhead in terms or power and temperature. It can give a small boost, that in real-life scenario, isn't noticeable (200 Mhz diff). And that small diff is normal for PBO.

So does it throttle at 80c because I am using stock cooler and it seems it starts moving down in ghz near that temperature. I plan on upgrading cooler soon

 

[Aeacus]

With stock cooler, high temps under load are essentially given. Since there are few coolers that are worse than stock. But many which are better.

and it seems it starts moving down in ghz near that temperature

That's essentially thermal throttle. CPU will limit it's frequency when temp gets too high, so that the chip won't cook itself.
Your CPU Tjmax is 95C.

It’s not reaching TJmax but I did just a buy a thermalright peerless assassin. So does this processor throttle at 80c cause it seems to drop from 4.4ghz when it hits that temperature. Also with PBO enabled it stays around the 4.4Ghz point but with it disabled it stays about 4.2Ghz point with a cooler temperature is that normal?

R5 5600X default setting for thermal throttle is 80C and up. R5 5600 isn't much different from the X-version and i think it shares the same thresholds.

should it be hitting 4.4 with pbo disabled? It only boosts to 4.4 when running applications or something intensive occurs in a game but with pbo enabled it is able to stay at 4.4 (as long as temps remain below 80)

 

[Aeacus]

should it be hitting 4.4 with pbo disabled?

PBO can go as high as official specs for the CPU are. So, with PBO disabled, there must remain some headroom for PBO.

Here's in-depth description what PBO (and PB, PB2, AutoOC) actually are + diff between them:
