Random Crashes with newly updated peripherals.

Yeah, if computer turn off and shutdown without BSOD or error, your PSU kicks in underload protection. Usually this is faulty PSU need to replaced.

Bad clock CPU/RAM will give error, bad HDD or SSD will freeze computer. A instant black screen shutdown, that is your PSU protection underload or overload protection. Mine was a HX750, been like that for months until I replaced it with EVGA SuperNOVA 850 G2, I haven't had the problem anymore.

I will consider replacing my PSU then. Before I buy a new one, what are the things I should look out for a new PSU?

Depends on your hardware. Like the reason it seems like it could be a power issue is that you changed the motherboard, probably to one that uses more power. A 1200 watt PSU is the upper-end of what most people can use. You could get away with less if you spec out if the CPU+MB+RAM+Video Card's power envelope, but when you see "oh 400 watts will be fine" consider that the PSU efficiency is only around 80%. So you could get away with 500 watts... if you have no other parts (some people have several hard drives, some have only one.) A 750 Watt PSU is probably the most you'd reasonably use in a non-SLI system.

Hello there! I just went home from work. I tried to re-socket my peripherals and for some reasons FFXIV didn't crash in an hour of game. I also did underclock my GPU. I am still testing for a longer game if it will crash.
