PSU Fried?

[Drafter]

Very weird issue has occurred, never before has this happened to me.

I was down stairs cooking, PC was on and working, I come up stairs and it’s off. I try powering it on and it instantly turns off. We are talking like half a second and it’s off. So I assumed it was a PSU issue. I unplug the 6 pin out of my GPU (I have a 6 and an 8 pin) and it booted up. Nothing came on my screen, but it booted up. Does this mean my PSU is not giving enough power? When I plug the 6 pin back into the PC while it’s on, it instantly shuts down

PC specs
i9 9900k 8 cores 16 threads
GTX 2060
16gb DDR4 ram
1 TB HDD x2
250gb SSD
750W Power supply

PSU’s are much cheaper than a GPU. So if anyone who’s been doing PC’s for a long time knows, please let me know! Also, the power supply is pretty old. It was around 160 when I got it 5 years ago. (Might be older)

750W Power supply

Not all PSUs are equal so while 750W sounds great it is no better than having 400W if the PSU is not a good brand.

What is the brand and model name or number of the PSU.

First thing I suggest you try is to remove the GTX 2060 from the PCI-E slot on the MB and hook up the screen to the appropriate video port on the MB, reseat the RAM, check that all internal connections are secure, power up to see if you get any video then post back with an update.
