Power supply issue?

post #1 of 5
Thread Starter 
Hey everyone, just got myself a new rig a month ago, haven't been able to game much though. But now that I've got some games installed, I'm noticing some weird stuff.

So when I'm playing relatively less intensive games like Dota 2 or World of Warcraft, there's no problems. But when I run Crysis 3 or Call of Duty Ghosts, everything runs perfect at 1080P with AA, highest settings and all that jazz, but randomly (sometimes 10 minutes, sometimes 15, sometimes 5) the screen turns green with vertical lines or just blacks out, but I can hear sounds for a few seconds. Basically the PC doesn't respond and I have to shut it down and start it again, then everything works perfectly well. I suspected the graphics card might be faulty, so ran FurMark and had absolutely no problems or artifacts. Plus, my temps seem pretty fine, the proc hits around 65 degrees Celsius and the card hits about 76 or so.

I tried the following:
1. Changed RAM slots.
2. Reseated the graphics card.
3. Changed my power cable.
4. Reinstalled drivers.

Here are my PC specs:
Intel Core i5-4670 Processor
Gigabyte H87M-D3H Motherboard
G.Skill RipJawsX [F3-10666CL9S-4GBXL] x2 (8 GB) RAM
Sapphire AMD Radeon R9 280X Dual-X 3GB Graphics Card
CoolerMaster Hyper TX3 Evo CPU Cooler
CoolerMaster Thunder 600W PSU
CoolerMaster Elite 431 Plus Case
Seagate Barracuda 1TB HDD

I suspect the PSU is not able to handle the load, could that be the problem?

That really doesn't sound like a PSU issue to me. According to its specs, the PSU should have more than enough power for your rather low-power system. You will never top 400W (and I'm being very generous here) and your PSU is specced for over 550W at +12V.
If Cooler Master fudged their numbers again however (that's not unlike them, historically), then who knows what the PSU is actually capable of...

Any idea what else it could be? Because it doesn't seem like an overheating issue, Furmark tests were stable.

You should get rid of that PSU you have ASAP before it kills you PC

Just an update, the beta drivers let me play Crysis 3 for longer than usual, but the game started stuttering after a while and so does the PC. I'm running a VRAM stress test and will report back. I am actually considering changing the PSU, I just want to make sure of other problems.

Edit: Just ran Video Memory stress test, with the command to test all 3072 MB of VRAM, ran it on OpenGL. All the 3 tests (Small, Express and Full) show 0 errors.
