Is this a problem with my PSU? Or something else?

Hi guys. Right now when I play more graphically intensive games, my computer crashes, blue screens, or black screens and immediately restarts. All of the games run at their correct performance (fps-wise) but still crash very quickly. Crysis 3 runs for about 3 minutes and then crashes. Battlefield 4 single-player and test range works fine, but the multi-player crashes after about 1-4 minutes.

An empty match on Parcel Storm with clear weather (no waves/rain/wind) does not crash. But a decently filled match on Parcel Storm during a storm will crash in a matter of almost a minute. This made me think that it may be the ram, because it obviously takes up more ram when more people are present and you have to render more events on the map. I thought that maybe when my ram fills up to a certain amount, my computer crashes.

I ran memtest86 to see if it was the ram. Passed 9 times over 18 hours, seemed fine, but I still have a slight feeling it may be the ram. I may try later to run with just one stick and see what happens. I think I'm narrowing it down to my PSU because if i run my CPU and GPU at base clocks, the problem persists. Originally I had my GPU to ~1250 Mhz (Should be okay with the SC version of my card) and my CPU at 4.5 Ghz (Should be okay because I have a good cooler.).

I'm running a:
CPU: i7 4770k
GPU: GTX 780 ti SC ACX
RAM: G.skill Ares 16 gb
MOBO: Asus Maximus VI Hero
PSU: Corsair 650 Watt platinum certified.
CPU Cooler: Phanteks PH-TC14PE

I'm kind of disappointed at the fact that this may be a PSU problem considering that the one I got is supposed to be top of the line. Did I get one that doesn't have enough power to support these games? Or is it just a lemon? Or might it be something else?

I'm at a loss here. I'm going to test prime95 on my CPU because on FurMark tests for my GPU, it performs fine. Thanks to anyone who considered helping.

Yes BSOD is normal when CPU not given necessary power under OC. But you said you don't experienced on OC, take care; for a good OC you need know all parameters on your bios motherboard and what for is used.
There is no 'should be ok' when overclocking, as all chips are different. I have the HAWK variant of the 760, and it 'should' be a great overclocked, but won't go more than +25MHz on the core beforing failing out. That PSU has plenty of power for what you're running. Your build won't pull a hair over 400w. I would try the single stick of RAM method, testing each one in a different DIMM slot and see what happens.

though both do have great cooling solutions; whats your temps for the cpu and gpu?

you are/were overclocking - are you sure its stable? (prime95 will answer that) have you tried different graphics drivers?

i am not thinking it's the RAM or the PSU; albeit there isn't much headroom w/650 watts but that ought to be stable.
 
There is massive amounts of headroom with 650w.

If Furmark doesn't crash, it's not a GPU problem, that will pull about as much power out of the GPU as possible lol Get something like Piriform Speccy and monitor your temps when you are playing the games that crash, see what your CPU/GPU/Motherboard/RAM are coming in at.

My temps while under load are 50-60 c on both the cpu and gpu while playing these higher end games. I'll try to run with one stick. Also, I was messing around on the test range in bf4, and after about 15 minutes, it blue screened with a WHEA_UNCORRECTABLE _ERROR. Thats not good. On top of that, I dont know if it means anything, but my computer beeps once when it starts. Does that mean anything? I know certain beep patterns on startup mean something could be wrong.

one beep is good; thats the proper signal the computer is botting up.

getting a WHEA_ERROR most likely means your cpu needs more voltage - but you'll need to give more info before that would be confirmed, like what IS the vcore?



no, not really. but lets avoid remarks back and forth, eh?

My CPU Core voltage offset is at 1.25. Did I set something up wrong in my overclocking for my cpu? I'm not too experienced with processor overclocking and I dont know if I entered the main voltage it should be in the right spot, which is the core voltage offset.

Also, I cannot find where you adjust vcore options. I may have goofed big time.

This is cause your problem; you can't stable any overclock in games with this(auto) voltage. You need 1,28v; 1,3v 1,32v, 1.35v...or more, depending your OC. A CPU need "x" volts for max perfs and stability; another same CPU need more volts for same OC. I have i7 3770k at 4.9Ghz stable on 1,45V. I put 1,465v for more performance with a little temps gain without problems since 2 years; it's in very good watercooling. I saw another i7 3770k at 4.9Ghz stable with only 1,35v.

Thank you very much for identifying the problem. Ive gone through a bunch of threads and none of them came up with underpowered cpu's as the issue. So thank you for that. I'll be adjusting according to what works. Also, are crashes like these normal when a cpu is not given enough power?
