power supply Triggered PSU protection, should i switch to a new PSU?

[ILoveFox]

I recently brought the new rx 5700 xt. The PC shut down while gaming or doing heavy GPU benchmark. The screen went black and need to turn PSU on and off in order to run windows again. I did some research, the problem caused by PSU protection. So the question now is, am i right?

I have this PSU rn

I did a GPU driver clean reinstall (driver version 20.5.1)

I checked the 12v, its above 12, but sometimes it dropped to 11.95 something. I think the voltage is fine. (maybe i am wrong, i can post the sensor report here if you need)

 

This is my gpu GIGABYTE AORUS Radeon RX 5700 XT 8G Graphics Card, PCIe 4.0, 8GB 256-Bit GDDR6, 2010 MHz Boost

 

Right now i set it to 1150mv core voltage and 1900 Mhz core clock ( i set it to 1200mv, and it triggered the PSU protection once)

i am thinking of buying a new one.

That is a terrible power supply.  That's made to be used with a graphics card like an RX560 or a GT 1030.  Not a $400 RX 5700 XT.

Sounds like you did research in the wrong places.

 

While it could be the PSU, it's not a "protection".  When a PSU protection kicks in, the PSU shuts off.  If your screen went black but the PSU stayed on, that's not a protection kicking in.

do you get any msg when you turn ON the PC?

It doesn't mean necessarly it's PSU fault.

I never heard of N1 from EVGA...

try to borrow other PSU and eliminate it from equation.

If PC reboots could be AMD driver issue or you have heat problems...

You've managed to grab one of the worst 'branded' PSUs on the market, replace it ASAP.

Not entirely true. PSUs can be designed to "crowbar". That means shorting the output straight to common in order to prevent any current from reaching the load. During this crowbar state, the PSU is still functioning, just that the load (the rest of your components) are not getting any power. That crowbar cannot be reset without a power cycle. Although that's usually reserved for linear supplies...

 

To OP: Connect your GPU to the PSU using 2 PCIE power cables, not a single one with two connectors on it. Then try again.

But OP's psu has only one cable(with two 6+2 pin ends).

Damn that sucks. Looks like a new PSU is in order.
