Hello.

I recently came across a problem with my GPU, I suspect that it's shorting. Since the PSU doesn't let the computer start when the GPU is connected to the 8 pin cable (Fans spins for a second).

I ordered a new GPU Gtx 1650 and a new PSU P450b 450w.

I'm wondering what is the safest way of isolating the problem.

Testing the old GPU RX 480 (4.5 years of use) with the new PSU.
or
Testing the old PSU with the new GPU.

I don't want to damage any components in the process.

Thanks for taking the time to read this.

Technically, you can use the paperclip test to check the PSU. You can purchase an inexpensive tester which will tell you the rail voltages, or a meter if you are familiar with their use.
Side note, if they are modular DO NOT mix the power cables.

As to the GPU...I am not aware of a way to check it without installing it. I hope that isn't it both for the new PSU as well as the price of GPU in general.
