ASUS PSU surge

[GrandJohn]

Had this computer for about a month now. Just installed Windows 10 about 1 day ago, and started playing some Rust and then the screen goes black. Nothing was working, so I just turned it off by the switches (I know I'm stupid). Just thought I might have knocked a cable or something, so I carried on as normal. Launched Rust back up and played for a good 2 hours, and it happens again, this time I wait, and a message pops up about ASUS anti surge detected an unstable psu (Didn't really read it).

So I'm thinking if I should just turn off anti surge or could it be a problem with the PSU...

What do you guys think?

Thanks ;p

Also, I have ran like benchmarks and such for my GPU and lowered the power limit to -20%, no crashes while doing any of this.
