I'm running cpuz stress test so all 12 cores are 100%. Hardware info is reporting the following RED warning.
What is this and should I be worried?

I wouldn't worry if your voltages and temps are good.
It's pulling more power than it should (at least more power than it is reporting) but if the CPU and VRM temps are good, it probably just means you are getting a little extra performance.

If you have deliberately enabled PBO or altered CPU power limits from stock then ignore it. However, if not disable PBO manually rather than leaving it on auto and see whether it makes any difference (unfortunately Gigabyte could be juicing the CPU at 'stock' and trying to hide it which is precisely what this power deviation metric is supposed to discourage).

If that still doesn't work you could try setting the CPU voltage to 'normal' rather than 'auto'.

I get this on mine from time to time with no PBO enabled or overclock. Never caused an issue in the 12 months I've ran a 5900x.
That's good, but it can cause issues though if you don't have the best chip or a great cooler. It's unnecessarily overvolting the chip, wasting power and creating heat for no good reason other than to gain a couple of percent extra performance and make the motherboard 'look better'. Personally I want to know when my CPU is not at stock settings and have the ability to choose, these manufacturers wind me up when they effectively cheat to win benchmarks by a tiny margin.
A power deviation of 89/90% at the lowest is normal but going down to 75% implies they are doing something dodgy.

I've got the X570 Tomahawk, MSI have always pushed more voltage than other brands with the Ryzen chips in my experience.
Gigabyte have got that reputation too, thankfully my X570 Master doesn't really do it, voltages seem reasonable and the lowest power deviation I have seen is about 88%.
Just ran at stock, no PBO enabled.
B550 elite V2 board. I'll have a look and see what the normal and auto voltages thing is. Thanks for the info @itron

I love the way that says "But if the result is <90% or > 110% it should be of concern"
Show me a single motherboard with any BIOS setting where that readout is not red, i have a setting in my BIOS that switches between the motherboard controlling the power and the CPU controlling the power, it doesn't matter what setting i use HWInfo always reports the same thing, the same thing you are seeing in this screen shot, they say its because the motherboard is under reporting the power values, so how does it still report the same thing when its the CPU controlling power? Also how does it know, if the motherboard in under reporting power levels then where are they getting the real levels from to know that and to know what the percentage difference is? they are not using a voltage meter on the 12v EPS are they???????
IGNORE IT

My 5900x + Gigabyte B550 Vision DP does the same, shows 78% during CB23 runs. Definitely puts more than 142W through the CPU at stock, probably more like 180W which is in line with 142/0.78 value and matches up with the increase from 90W idle to 300W load at the wall (allowing for ~10% power loss at the PSU etc). Temps are insane too, pushing 90C on custom water which 30C coolant.
Swapped the Gigabyte board for a low end MSI B450 Pro and the power deviation is a bit above 100%, wall consumption drops to 230W under CB23 load, temps to around 60C.
Put in a MSI X470 Gaming Pro Carbon Max Wifi and the power deviation was 100±0.1% and wall consumption was 245W. These are exactly what I expect for a 142W draw.
All these runs were done at "optimised defaults" with XMP enabled. Playing around with PBO settings in the Gigabyte board does weird things (on = eco 65W, off = ~20W less than stock). My solution has been to use 111W as the PPT in bios as 111/0.78=142W and I get similar temps, power draw and performance to the MSI x470 board.

See above. Don't know exactly how it's calculated but I'd guess they take a current and voltage reading and manually calculate power from that and compare it to the incorrect power reported.I love the way that says "But if the result is <90% or > 110% it should be of concern"

Strange, my Gigabyte X570 Master doesn't do this (at least not to this extent), the lowest I've seen is about 88% and under heavy load it's often well above 90%. Why Gigabyte are doing this much more with some boards than others is beyond me.
Those are some very nice power and temperature savings with the MSI board.

Yeah it's just a shame that the Gigabyte board looks better, has better RGB support and can do fan speed adjustments based on a thermocouple that is inside my reservoir without any software running. It's vain but those tiny little edges here and there often make the difference between board x and board y.
