Custom PC Build Keeps Cutting Out - Help Please

Hello,

I have rcently built a new PC and it keeps randomly cutting out. The best way I can describe it is like you have overclocked your CPU too much and the PC just cuts out / shuts down. The mobo rgb lights stay on as do the case fans. I have to hold the power button down to turn off the PC, or sometimes this doesn't work and I have to turn off the PSU switch.

It's not temps as cpu doesn't break 70c under 100% load, gpu is around 70c at 100% load.

This problem has happened while the PC is idle and also while playing games.

The PC is set to defaults now, no OC. I thought it might have been the PSU as i kept this from my 7 yr old PC. I've bought a new PSU and the problem still occurs.

Build is: Lian Li O11 Dynamic Case Ryzen 5 2600 CPU Asus Prime X370-PRO mobo Zotac RTX 2060 GPU Corsair PSU 850w (new PSU 750w) Corsair Vengeance Lpx 16gb (2 X 8gb) Memory Kit Pc4-19200 2400mhz Ddr4 Dimm C14 Deepcool Castle 360 RGB AIO Deepcool RGB case fans x4

I would really appreciate your help as I am stumped by this and not sure where to go from here.

Thank you.

Still sounds like a PSU issue. Or possibly the GPU. Best thing to do is use the process of elimination. I know its rough but try swapping the GPU first since it would be easy then swap the PSU if need be.

Thanks for your reply Hemi. I'm currently doing that 1 at a time. Swapped my GPU back to my old one for now and testing.

I have the exact problem. Thought it would be PSU related but it keeps doing the same with my new PSU. I just don't have another GPU to install to see if that's causing it.

UPDATE: I'm still having this issue.

I have ruled out the following by either disconnecting/replacing/using old: GPU, PSU, PC Case, RGB lighting, RGB hubs/cable, Case fans, Motherboard

I've just replaced the motherbaord and still have the issue. I'm currently trying a different SSD drive with a fresh Windows install.

After that there really is only the CPU, RAM and CPU AIO cooler left.
