While using the computer abruptly restarted and went into windows troubleshooting..
So I did fresh install, yet it persisted,so swapped ssd yet persisted, swapped GPU , RAM, resetted CMOS, tried same PSU in other PC works fine even in high load .
I Observed that there was current in the crossair case near the PSU area...,
So what could be the reason ?

AMD RYZEN 5 3600
XPG RAM 8GB * 2
ASROCK 450H STEEL LEGEND
SILVERSTONE 500W PSU 80+
