Computer experiencing frequent random power cuts.

[Zedithius]

The problem is simple: When the computer is turned on it immediately powers up (as normal), the fans start spinning, the ‘Gigabyte’ on the video card lights up and then a second later the whole system powers off like it was shut down. However, after a few hours of being left alone, it’s able to boot up again normally all the way into windows but then will power off again at a random interval after turning on, which ranges from 20 minutes to a couple of days and the problem will persist again.

I’ve tried two different PSUs and power cords – No Cigar

I’ve managed to get it booted long enough to do 2 passes of Memtest86 and I’ve tried with a couple different sticks of working RAM – Problem continues

I’ve taken everything out of it except for the CPU and RAM (PSU still connected obv.) and the problem persists.

I’m too scared to try and update my BIOS in case it powers off in the middle of the update and cracks the entire system even worse than it already is.

I’m at a complete loss and I don’t have a spare 10^th gen board or CPU to test and I don’t want to buy a new board/CPU just to test this, but I may have to.

Thanks for your time.

Have you tried a different outlet?

I don't see THAT BIOS version on the ASUS website.

BIOS version is usually something like version 1620, or 1602, etc.

 

What is the the make + model of the other PSU you used to test with?

 

Are you using a single daisy-chain cable to your RTX 2060 Super, or two separate cables?

If I have the model correct, the Gigabyte RTX 2060 Super Gaming OC needs a PCI-E 6-pin and 8-pin.

 

Take everything out, did you try running the system WITHOUT the RTX 2060 Super?

So only using the Intel iGPU for display output.

Was it STILL having power cut problems?

That BIOS version was was i could see before it cut out again, apologies for that.

The second and third PSUs I used were all identical models to the first, and was using the daisy chained connectors.

As I said I have tried the machine with EVERYTHING out except for: Motherboard, CPU, RAM and the PSU and it experiences the same problem, so it probably isn't the card's fault.

I'm thinking CPU? Because I had some overheating problems before the problem started so maybe the CPU is heat damaged?
