PC resetting while gaming

[Seba0855]

Hi. I recently bought new parts to my computer (CPU, MOBO, RAMs and cooler) and after a month of using it I've noticed that my PC randomly resets while gaming. I'm not facing this problem in every game I play, but it resets especially when I play A way out, Hearts of Iron IV, No Man's Sky etc.

I think the problem is with my PSU, because it's 550W Cooler Master. But on the other hand, before I bought it, I had checked on the PSU calculator if I needed a new one and it told me that 550 W is enough.

I'm almost sure it's not a problem with temperatures, because I checked them and they are fine.

 

On the old setup everything worked fine.

 

My PC specs:

System: Windows 10 Home 64 bit

MOBO: MSI Z370 Tomahawk (the old one was MSI B75A-G43)

CPU: i5 8600K (old - i5 3470)

GPU: MSI GTX 970

RAM: 2x 8GB Corsair Vengeance LPX DDR4 3000 MHz CL16 (old - 2x 8GB Crucial Ballistix DDR3 1600 MHz)

Cooler: SilentiumPC Fortis 3 (old - SilentiumPC Fera 2)

PSU: CoolerMaster G550M

Case: SilentiumPC Gladius X60

SSD: Samsung 840 Evo 250 GB (system drive)

HDD: Seagate Barracuda 1 TB

 

I made a test with OCCT and some other programs, the results are below

from my experience i used a psu calc which said about 550w should easily be good and still went with a 600w just in case. my computer would turn off instantly when playing games and running the gpu part of userbenchmark. i got a 750w and it fixed all my problems, this could be your issue. you can check your ram with memtest86 to see if thats the issue or not as well

Is your CPU overclocked by any chance?

Nope, I haven't overclocked it yet.

I used windows diag tool for ram testing, but in case I will also check them with memtest. I thought that 550W is probably not enough for this setup. What PSU should I have then in my PC? 650W or 750W? Will I have to pay more for electricity bill after switching to 750W?

That PSU was rather low end one when new, so might have reached its design goal.

Because there's nothing in that PC which wouldn't be easily handled by quality 550W PSU.

Unless getting still higher efficiency class PSU heavy oversizing always lowers PSU's efficiency some during most of PCs power on hours.

i'm kind of in the same situation.. but I dont want to start a new thread.. 

current PC setup. 

G3258 

Cooler Master Hyper 212 (With 2 linus special edition Noctua fans) 

MSI Z97 Gaming 7 (1st gen = no integrated AC wifi)

16GB 2133 DDR3 Mushkin enhanced Black RAM 

500GB Samsung SSD 840

EVGA GTX980 SC ACX2

EVGA SuperNova G2 750W 

 

The CPU has been OCd to 4.3GHz for most of the past 4 years (which might not help stability after 4 years) its temps are great.. generally around 70'c on load. 

The PC is almost always on. 

 

My PC recently started to reboot while playing PUBG.   (I know right, a G3258 running PUBG !!?... you better believe it)

at first i thought it was just a glitch.. but it did it again and again... so I decided to ge back to the 3..2GHz original frequency... 

with 3.2GHz the game is a bit choppier but still playable.. but it didn't reboot.  

However over the past week,the PC did reboot during the day. the first few times I assumed that some Update had been pushed by microsoft and forced to reboot the PC. 

so yesterday i installed Intel Extreme Tuning Utility. set the PC at 4.2GHz and stress tested it.. it took about 20 min until it crashed/rebooted. tried it a second time at base freq(3.2GHz) it ran the stress test long enough that i went to sleep. the next day, intel XTU says it had crashed and rebooted. 

 

So, i'm getting a 4790k next week and i'm wondering if the problem comes from the old CPU or the PSU.. since its been OCd for aboout 4 years and left on most of the time.. 

 

Is there a way to diagnose a dying PSU ? 

If its the CPU.. thats no problem because I'm getting a new one. I just don't want to find out the PSU is broken after installing the 4790k and having to go through RMA.. 

 

Thanks guys
