Hello Everyone, I posted a thread recently about my computer being shut down when I ran 3d mark 11 or games. Here is some information from the old thread:
I just built a new system recently and found a serious problem. When I do some gaming test (SCII, CSGO), the computer will shut off after ~5-10mins. Here is my major parts:
CPU: intel i7 6700k
cooler: corsair H90
MB: ASUS MVIII ranger
RAM: GSKILL DDR4-3000 15-15-15-35 2*8G
Video Card: EVGA GTX970 SSC ACX2.0
PS: corsair RM850
SSD: samsung 850 evo 500g
HDD: Seagate 1.5TB from my old system. (All games are in here)
OS: win7 64bit
I tried to diagnose the problem. I monitored the temp and fan of the CPU and GPU. CPU is at ~25-30 during idle and 40-50 during gaming. GPU is at ~30 during idle and ~50-60 during gaming. First I use the EVGA precision X to turn on the fan even during idle and test. Then when I ran SCII in all high setting I can hear the fan spin kind of loudly and then the system shut down. Then I did not use the EVGA precision X and test it again. It still shut down after ~5mins. I try to feel the temp of the CPU and GPU and I can feel the GPU is very warm and CPU is fine. I also use the Prime95 for a pressure test (max heat) and the CPU went to ~70 and it stays without shut down the computer.
I did more test I feel I can locate the problem. I don't know if I can conclude this and start more further action on RMA.
I borrowed another rig from my friends with EVGA GTX970 FTW 2.0, which is very similar to my SSC ACX2.0. I swap the video card and test each of them with 3D Mark 11 and see the stability.
Firstly I put my friend's FTW 2.0 in my rig which was powered with 2*6pin PCI-E power. The 3D mark 11 was ran once under both default fan profile and custom fan profile. The test was finished without any event on both modes. (NO sudden shut off or warning of overheating) The highest GPU temp was read as 75C based on HWMonitor.
Then I put my SSC ACX 2.0 into his 4970k system + gigabyte Z97X gaming MB. Also I realized that my card was powered with a 8+6pin PCI-E power. I feel kind of surprising since I think the FTW 2.0 should be a higher end card compared with mine but it was powered with only a 6+6. I don't know why EVGA design like this. His rig was powered with a EVGA supernova PSU. I did not install the precision X in his system so I just ran it in default fan profile. The test was still done without any event. The highest GPU temp was read as 77C based on HWMonitor.
Initially I thought the problem was due to my video card overheating but it seems not true based on my swap test. I feel the problem comes from the power supply of the video card. When I use FTW with the 6+6 pin power, the system looks stable under gaming (I still test it in CSGO for 20mins). But it cannot survive under my SSC ACX2.0 with 8+6 pin power. It may cause some kind of over-current protection on PSU and it shut down my computer under load when I use 8+6.
So is it the time to conclude this and find an alternative PSU? I was very disappointed with Corsair products this time. I may initiate a refund and send it back.
So I got some useful advice and I go ahead and bought a new EVGA supernova 850 G2 PSU. But I was shocked that my problem is not solved. My computer still shut down when I ran 3d mark 11.
Then I took all the part out of the case and test it outside. It got a little bit better but still not very good. It may survive for more scenes and passed the whole test once. But most of the time my computer still shut down. Under custom fan profile from EVGA precision X, my computer will shut down every time when I ran 3d mark. It will be a little bit better under default fan profile (no EVGA precision X app) but most of the time it still shut down. The max GPU temp was read as 78C from HWmonitor.
So I feel really lost right now. I don't know which part cause the problem. It seems the PSU is not the cause since it will be less possible I bought 2 failed PSUs. I may will initiate the return process of my video card first and find another one. I worked on this problem for ~10days and feel really tired of this. Any kind of help will be very appreciated.
