System Reboot Instead of Power Down

[swathe]

6/10 times, especially after long use or when I game. Everytime I shutdown Windows it will become a reboot. I suspect it to be during the shutdown sequence it has an issue then the system auto reboot.

Other symptoms I have encountered is that, if i am playing a mid range game, the PSU suddenly cuts off power and reboot. It feel that it is a power cut off because unlike a usual hang auto reboot, I can hear the entire system power down and power up.

Eg, it feels like the reboot when you upgrade your BIOS, rather than a windows restart.

Is this a PSU issue and need to RMA?

Paiseh, Sandy Bridge i5-2xxx.

I tried changing GPU, also the same problem. Never tried Intel GPU because old setup. Mobo no graphics port, so only use discrete PCI-E Cards.

Never overclock anything, all stock stuff. Highest temp was 60+ degrees only.

What is the game? Does the game have any recent updates?

World of Warships at 1080, medium. Not a very high demanding game.

Game is updated at launch. nVidia drivers also the most current.

Should I just RMA the PSU? Likely not GPU issue because I changed it once.
