Faulty Power Supply?

[snakegb]

hi

Last week during gaming my system hard powered down, since then its happened 3 times, only happens while playing Path of Exile and thats not an intense game
Cpu temp is only at 60c

Is this a sure sign my power supply is dying?

Could it be a software issue?

or something else

is there any way of tracking the problem or am i just guessing?

Thanks

It's now happening just browsing/ idling in windows

Gpu at stock,
Haven't lowered overclock yet but would that prove anything as lowering the overclock would also reduce power consumption wouldn't it.
