My system is very basic at present. 2200G on B350, 2 regular hard disks. No discrete GPU. Present PSU is CX450.
But for the last 2+ years I am tearing my hair out due to either system refusing to power on at all or randomly shutting down. A slight fluctuation in ac voltage causes hard instant shutdown, sometimes followed by reboot by itself.
In general we have constant power fluctuations.
Earthing is tested and found to be OK. UPS battery and board are both new. So now I want to try putting a better PSU and see. My target is to keep the PSU in its most relaxed state so that it won't give up during fluctuations.
If that works, then I plan to upgrade.
Budget wise 9K for RM650 feels too much. CX650 is also claimed to be fully modular. But is more budget friendly.
