Hi everyone...

Maybe posting here will help me understand why i'm getting this kind of issue, and hopefully solving it.

The thing is i'm getting continuos system shutdowns while playing the campaign on the new expansion of the game Heart Of the Swarm, it usually happens during conversations while on mission interludes or during missions themselves. The weird thing about this is that it only happens during campaign mode, all other modes work perfectly.

I've been monitoring GPU and CPU core temperatures but all values seem normal to me... i'm just lost about this and don't really know where to start looking, i've tried pretty much everything and can't seem to find any reasonable cause.

Any additional info needed, i'll be happy to provide.

Any help would be greatly appreciated!

Thanks.

I tested it on all setting levels, from low to extreme, happens on everyone of them.

Happened on first version and newest version of the game, been experimenting the problem from when i firsto got the game.

If you're monitoring temperatures and they're OK, then a complete shutdown is typically indicative of an overloaded power supply.  The one you have is actually a 600W unit (700W is the peak temporary load), and not a very good one at that. 

I'd recommend a single-rail replacement.  The Corsair TX650 is good mid-range model that should give you ample reliable power.

Thanks for the answer, i'll see what i can do about it.

The thing is, i can run pretty much everything on max settings, even Crysis 3, and it doesn't give me any kind of trouble, it only happens on Starcraft 2... and only during story mode... it's just plain weird that it has to be some power supply problem because it has never happened on any other game but this one, wouldn't it happen frequently and running other games if it was a power supply issue?

I'm speaking on pure supposition here, i don't actually know... But, well... wouldn't it be logical?

Anyway thanks for the answer

Eh I have 0 issue's playing SCII with my 7950s.

So if your entire system is just turning off... power issue.

Seriously? It happens only during one game and it is a power supply problem?

I can play more graphic-demanding games for hours and not a single shutdown has happened to me ever.

Sigh... well i'll have to check it out somehow, what would you guys recommend? Anything above 600W?

Well I'm throwing all my eggs into a power issue. Reason being is usually when a video card is the issue. It will crash in just about every 3d application you run. But you said your PC is simply "turning off". When a PC simply turns off that means power is being tripped. 9/10x out of 10 its a power issue. 

The other few times its going to be capicitors on a motherboard thats going bad. But usually those only go bad in server environments due to the high operating temp.

I've been on these forums a while now, and I've never had someone say "well replaceing the power supply didn't fix it my PC is still turning off" Not to say it hasn't happened. But I mean at this point there's not really much we can recommend.

Reason being is your not getting any .dmp files because the PC is simply shutting off. So there's not really any evidience of a software problem. 

I mean you can go through your system, and do a fresh install of windows ect.. just to be 100% certain for your own peace of mind. And if it continues to happen afterwords.... Its got to be power failure somewher.

As far as recommendations go...

Corsair, Seasonic , Enermax, XFX, Zippy, PC power and Cooling.

Well, just to clarify... it doesn't just shut down, it actually resets... it shuts down, then restarts itself... that's exactly what it does, no error message at all.

Oh well, getting a new power supply is not a bad move after all, might as well try and see if i can get the issue solved by doing that.

Anyway, it's just plain weird.

I'll let you know what happened once i can actually get my hands on one.

Thanks for the help guys.

That's definitely the power supply.

i have experienced that kind of problem before and it turned out my power supply is the problem.

Back then i was playing Lineage II then suddenly my pc just reset by itself, tried playing again and it reset again, the third time pc just won't turn on anymore and i smell a burnt component from my pc. I replaced the power supply and it turned on again and the pc didn't reset by itself again, problem solved.

So yeah, power supply.

Btw HOTS campaign is awesome.

Oh well, i'm definitely getting a new one then...

Maybe it's not the right place to ask but what's the difference between the Corsair TX series and GS series? Is any of them better than the other?

I'd appreciate some advice here guys. Since i don't know which way to go.

I have a Corsair TX850V2 and it can handle a pair of single GPU cards easily.

The older GS series are not as good as the TX line

the high end AX are excellent but $$$$
