Hi!
So, I've been having this problem for a while with my new PC (8 months, at max), it shuts down with no apparent reason, at random, and, also at random, sometimes it tries to restart, other times it just shuts down, although the power button still has the LED on. Due to what I could gather over the research I've made, it appears to be the PSU, nonetheless, im having a bad time admitting that due to three factors, First, the PSU is known to be reliable; Second, it is brand new; Third, the shut down only happened in idle situations, or internet browsing, it only happened in gaming on, at most, 5% of the times. I was considering formatting the pc, and getting a clean start, but the last time it happened I was on the BIOS, thus, I don't understand if the windows can still be a possible cause.
I had the PC on for over 4 days now, on suddenly it started to show the symptoms again, last time was about some time ago, and I thought I've had fixed by clearing the CMOS and removing one fan from the PC.
Note: This problem appeared out of nowhere, I don't recall a hardware change that may have caused it.
My specs:
Motherboard - Aorus B450M - F50 Driver
GPU - Gigabyte RX 5700 XT Gaming OC 8GB - Latest available driver
CPU - AMD Ryzen 3800X
Cooler - Cooler Master Hyper 212 RGB Black Edition
PSU - XFX XTR2 650W 80+ Gold
Memories - Team Group T-Force Delta 16GB 3200mhz (2x) - Memtest ok
Storage - GIGABYTE M.2 PCIe SSD 128GB/Western Digital Black 1TB/Crucial SSD MX500 500GB/Crucial SSD BX500 120GB
Other parts on PC:
Fans - 1 x Cooler Master Masterfan Pro 120mm/2 x Cooler Master Masterfan Pro 140mm/1 x Deep Cool FH-10 Fan controller/2 x Thermaltake Pure 14 ARGB Sync/1 x Cooler Master SF120 RGB (CPU);

What I've tried:
Memtest - Ok
CristalDiskInfo - Ok
Temperatures on HWInfo/MSI Afterburner/GPU-Z/CPU-Z - Ok
Stress test ran - Geek Bench/Fur Mark/GPU-Z Stress test - No problems in anyone of them.
Reseated the GPU, and Memories.
I would really love all the help you guys could give me, Im still able to swap parts on RMA, and I need to understand if the reason behind this is hardware to that end.
