Every time i would log in to play my game Revelations Online CB3 the computer randomly turns off then on again after 5 minutes of game play sometimes 15 min this ONLY happens when I game.
But if i do not game but browse the internet or watch YouTube for 1 hour nothing happens it doesn't randomly turns off weird ?

I have been reading all over the Forums and people have mentioned its a Power Supply Issue
OR Cpu/Gpu over heating issue ?
I've also heard someone mentioning something about 12v Rail psu issue idk ?
Could Cpu Thermal Paste be the problem?
Could settings like Power Management & Sleep Settings be the cause ?

My power supply is a EVGA SuperNova G2 750W 80+Gold which i bough brand new for $159AUD
Backed by a 10 years warranty, Surely it can't be a PSU issue right ?

Because i really don't wanna fork out another $150-$200AUS for a new PSU.

Please note this game is in Closed Beta 3 & i'm playing at Ultra Settings.
Am i running any 3rd party programs ? Yes MUDFISH: Acceleration As a Service.
How long ago did i build my PC Just under 1 year back in 2016.

It does sound like a power supply issue. Power supply dosen't have to be old to break, once I build a brand new PC for one of my costumers and just after 2 months, his computer would shutdown when he would try to open a game or watch a youtube video, it was also a Corsair PSU (can't remeber the model) with 3 year warranty, luckly he got anotherone free of charge with the warranty. If you want, you could try looking at your temptures, but I don't think that would be it. Try opening a benchmark like prime95 and select the max power consumption option and see how long it will take for the PC to shutdown.

If i want to get it replaced/RMA where is the best place to start?
Contacting the Online Store where i bought it in the first place OR contact EVGA and complete RMA/Defective paper works?
Sigh Evga company is all the way in the US and i'm all the way in Australia.

I believe you fillout a form on their website, and if they accept it, they will ask you to drop it off nearby EVGA warehouse/store. I have never returned anything to EVGA, but I have returned bunch of stuff from MSI and Corsair and that's how it normally works, so I assume EVGA has the same system.

Problem is theres no evga shop/store/company in Australia.
We only have computer stores/online stores that sells Computer Components/Parts which includes Evga products like Gpu & PSU.

Then I assume they will ask you to ship it to their warehouse, I'm not sure if they cover the costs of shipping or not, you would have to read they return policy and see what it says.

I'm gonna try programs like CPU Core Temp & Gpu Temp to check my temperature.
Maybe the thermal paste wasn't applied probably Or applied too thick?
Or maybe the Noctua Cooler is not alignment to the CPU properly Contact Problems ?

Or the GPU thermal paste needs to be replaced?

Or the PSU is not providing enough power to the GPU/Systems?

Temperature was fine when i was gaming today CPU at 43'C & GPU at 45'C.

OK i found another problem today when i was gaming on Revelations online CB3.
When I play on Blade-Master at the Large City's the computer turns off straightaway BUT if i play on Gunslinger at the Starting Zone it works fine.

Another problem i found out also is when i Stress Test my GPU on FurMark till myTemperatures reached 70'C the Computer doesn't Turns Off or Shut Down.

Then i downloaded Prime 95 to Stress Test my CPU i7 4790K 4.0ghz as soon as i click OK/Start the Computer Shuts Down and Turns on again.

SO what is the Problem Here ? ?
Is it my CPU ?
Is it my PSU ?
Is it my motherboard ?
is it my Noctua NH-D14 Cooler ?

Let's go back from the beggining. Was it like that from the beginning? Did you change something and this happened right after or some time after? Or it happened suddenly?
If i see correctly, your CPU is overclocked?
By the way, 1.476V vcore is high!

Ok I've managed to fix the problem it wasn't a power supply issue but a bios issue somthing to do with voltage & frequency unstable.
SO i went and updated the bios & drivers to the latest version problem solved no more shutting off while gaming.
