Defective MOBO or GPU?

[Lorentzze]

Hello, I'm facing serious issues with my GPU.

GPU load drops from 99% to 0 every few seconds in all game, causing fps drops from 75 to 10-20. (see attached) Clock remains stable when these drops occur.

I reinstalled windows, all drivers, DDU, etc.

Temps are good,78C max.

Now, I know that either my motherboard or GPU were damaged during shipment. The GPU is slightly bent,and sagging, and it sometimes won't send signal to the monitor until I push it slightly up. 
What could be the problem ? PSU not powerful enough ? damaged / corupted GPU? Bent pcie slot on GPU? broken pcie slot on mobo?

There is no visible damage to the mobo.

I already spent too much time trying to solve this, and I don't have that much time to begin with, ... If someone could please help me solve this madness that would be greatly appraciated. I really hope it's a graphics card issue only.

Thanks.

 

Specs:

GPU: MSI RX570 8gb

CPU: Ryzen 5 2600

MOBO: Asus a320m-k

RAM: Crucial 8gb DDR4 

PSU: Deepcool dn450 

Windows 10 pro

I would grab a better quality psu. Can’t find much about that specific model, but I’d say it isn’t good quality.

It is not good quality indeed. It came with my previous case. I ordered a corsair 650W PSU on Amazon, doubt it'll change anything. Still I'd like some advice regarding my actual problem.

Does it only occur during gaming loads or also other times ?

It seems to occur in Windows as well but not as frequently. When the gpu reaches 80-90-100% load is when it starts to go crazy.

Sounds like the PSU could in fact be your actual problem.

My PC was built in Italy and they assured me that it would be fully working once I receive it. I don't think they would send me a rig that does not work, at all. Would they? That's what lead me to believe that something got damaged during shipment.

From what I read on different forums a starved GPU would lead to a reboot eventually and I've never experienced such thing. The gpu load just drops for no reason as if I was constantly alt-tabbing to the desktop. Except there is never a single drop in clock speed. core and memory clock remain at 1366 and 2000mhz.

But maybe you're right. No way to tell until I receive a new PSU.

So I changed the PSU today for a 650W Corsair, problem is still here.
