Since installing a Titan GPU my PC is restarting (Starcraft II problem only)

Installed my Titan last night. Played SWTOR, FC3, TR and Crysis 3.

Today I've mostly been playing Starcraft II and 5 times now my PC has restared. I'll be playing, then boom, two beeps from my PSU and the whole PC restarts.

Full spec:
i7-2600k @ stock
16GB RAM
P8P67
256GB SSD
EVGA Titan
Enermax Infiniti 720W PSU

Temps are staying below 70 on the GPU.

Any ideas? is my PSU not capable of the Titan? Why is this only happening in Starcraft II, not exactly a demanding game?

I'm tempted to throw in my old 670 and see if it still does it.

They're solid.

Played TR for 3 hours last night, no issues at all. Seems to be only SCII that's causing the problems, odd.
 
My only guess would be that StarCraft 2 is heavily CPU bound so pushing both your CPU and GPU to the limit may be pushing the PSU too far. This shouldn't be a problem for a 720W power supply but it depends how the power is divided; maybe one rail is becoming overloaded.

Is it possible for you to check CPU + GPU usage (Task Manager, GPU-Z, MSi Afterburner) to monitor what percentage they rise to? Maybe maxing both of them out is causing the shutdown.

Alternatively, try Furmark and Prime 95 (using 7 threads, leave one thread for FurMark) and see if this causes a shut down. This is a purely synthetic worst case scenario. If it does, it is most likely something to do with your power supply.
 
I would look at pc memory/setting/voltage esp with 16gb,the titan is pushing your pc cpu and memory more now

might need a touch more vccio voltage or dram v or both
 
Maybe an issue with StarCraft?

Have you checked forums?

Edit:

I would be very surprised if the game would make your PC just restart. Sounds like something else as amiss. Do you have another PSU to try? Titan is very good at being power efficient and your PSU has enough oomph but it could be a fault with it.
 
Ok, three times in a row now at exactly the same point in the game. Starting to think this is a game issue perhaps?

Going to fire up BF3 in co-op with a mate and see how it goes.
 
Same point yet again, game restarts.

I only have a spare 400W PSU, not really good enough for my rig.

I'm really not wanting to spend any more money on my PC, I've just spent £1500 on a new GPU and monitor, my PSU should be fine for my rig? Sure it's dated but it was one of the best around in its time and definitely not bad now. :(
 
I have Prime95 and FurMark going side by side now, for at least 10 minutes.

CPU vcore 1.2V
GPU vcore 0.962V
CPU temp no higher than 60 on all cores
GPU temp 80
 
It has to be game related then Chris.

Check the forums and I will see if I can find anything as well.

Edit:

After not long of searching, I see this game is a bit of a mess with errors for everyone.

You can try some of the fixes here:

All pretty standardised and none of those should be needed. It doesn't seem to like multicore CPU's from lots of reading, so I would give disabling a couple of cores a try.

Most threads I found were when the original game was released, this is 2 years on.

Hmm, so it crashes when you just about finish feeding the ancient one mission. It was fine here on my 7950. But yes, try a different set of drivers and see if that helps.
 
I would leave the game alone for a week, play everything else under the sun and see if you get the same again.

There is certainly a stability quirk here, but it may well be driver related. Titan aspects of drivers are still early days yet.

And throwing in your old 670 to see if it does it isn't such a bad idea, if you are using the same driver set.
 
Does Starcraft II have very high framerates, I have noticed when benching that a stable CPU overclock can become unstable in a benchmark if the difficulty settings are reduced resulting in very high framerates.
 
Geforce Titan is like the Chuck Norris of GPUs. It saw the Core i7 2600K at stock clockspeed,and thought it was not worth continuing as a result,since it was too weak and not awesome enough to handle Titan POWAR!!
