PC randomly shutting off - PSU not the issue!

[Jimmy 8x]

So, my pc is randomly shutting off with no error screen or beep or anything. No discernible pattern to when it happens, and it's definitely not overheating or in high load scenarios only. It even happened once on very initial boot up when it was on the ASRock screen...

 

Never happened before until the other day. I built it in March. 

 

So far I've only eliminated the power supply as possible culprit. New psu installed and it's still happening.
 

Specs, if they're relevant at all..

 

Case: Corsair 280x

CPU: AMD Ryzen 5 3600X

Mobo: Asrock X570m Pro4

RAM: Corsair RGB Vengeance 3200mhz

GPU: Asus Strix 2070 SUPER

 

Not sure what my next steps should be.. I don't exactly have a spare motherboard lying around to see if that is the issue..

 

Tonight I'm going to fully check and re-connect every connection on the motherboard.. just make sure there are no loose connections or anything..

 

Any tips or suggestions are appreciated, thanks.

This was happening to me an ASUS board with 4 RAM sticks. The board didn't supply enough current to DRAM. I had to increase the DRAM Current Capability from default 100% to 120% in the BIOS. It has been rock solid since then even after heavy DRAM OC.

I do have 4 ram sticks..

 

But, I have had 4 ram sticks for a few months now, with no issues.

I had it happen in specific workloads. For example I could play PUBG for hours without issue but Apex Legends would trigger the shut down immediately after loading screen every single time. Memtest86 would trigger it as well after about 15min of running. 

Encoding videos for about an hour would not trigger it.

Are your stick identical with same latency? did they come in pairs?
Are you using XMP ?

Not sure if you are talking about mine or the guy whose issue is long in the past

 

My ram is all identical and running in xmp

It's all the same sticks but two kits of 2x16GB 3200CL16.
