Question GPU drawing half the max power at max utilization

[LoonyMoony]

I just updated to a Radeon 7800 xt from rtx 2060 super, I got a new 850W psu for it as well. I've been getting less fps than my previous card consistantly on all games, and when I check AMD software it shows that only around half the power is used (board power). I've reinstalled the card physically several times, and I'm sure the cables are all plugged in. The slot on motherboard should be fine too as I had a card on it before this.
Cpu intel i7 10700KF
24gb ram

I donno what to do I've reinstalled graphic driver as well, also used ddu for nvidia driver.

Did you use only the cables that came with the new PSU?

Make and model 850W PSU?

CORSAIR RM Series (2021) 850W, yes all the cable connected to the psu came with the psu.​

Download, install and or run GPU-Z. With a game running, press alt + tab on keyboard to go back to GPU-Z and see if it shows under the Graphics Card tab and where it says Bus Interface, that it says "PCIe x16 4.0 at x16 3.0", like it should be when running a game. When a game is not running it should be dropping to "at x16 1.1" or 2.0, to save power.

I don't remember if AMD Adrenaline will show the bus interface like GPU-Z or also CPU-Z.

Yes it shows it at 3.0. Also seem to be 3.0 on idle though. However I used the stress test built into adrenaline and during the test the gpu was using 250W of power. I assume this means hardware is fine... so driver issue? Others don't seem to be having problem on this driver and i've rolled back and tried a few versions as well some perform better than others but all under expectation

There is a possibility that the GPUs vbios has a bug or something else with the card wrong. There could also be an issue with your Windows power management settings. Maybe setting everything back to defaults will fix it, since something might have messed with them at some point.

You could also try updating the motherboard chipset drivers. Windows might have already installed the newest version, but it's possible it's on an older possibly buggy version. This probably wont change anything though.

The last thing to try is a fresh Windows 11 install to make sure everything is back to "normal", but again, this is the last thing to try if there are no other solutions. I personally would install it to a new drive for testing, but I have a bunch of extras, so I wouldn't expect that to be an option for you.

I'd consider doing an RMA and explain what is happening, they might have a solution or just replace the card for you. You might also want to just return for replacement or refund if you are still within the return period with the retailer.
