PC Restarting randomly mid Game

Nutkin · 13 May 2017 at 20:40

Hi I Have the following,

i5 7600K
MSI Gaming M5
16Gb Balistix Ram 2400
M.2 512Gb
MSI 1070
G1 EVGA 650W PSU

Cooled by 2 case fans in the S340 Elite and a H100i V2

I have found that my pc goes into a fit of restarts when I have been gaming a while and will restart constantly before bios for a bit before eventually becoming stable again, this can be induced by using a GPU+CPU stress test for approx 20 mins.

I cannot for the life of me work out what is Overheating, everything seems to sit at OK temperatures CPU is at about 50 Degrees GPU sits at a Solid 70 no issues.

The fact it constantly resets for about 6 or 7 times then eventually boots again seems to me like something is too hot and its waiting for it to cool down before it can boot fully and be stable.

Is your system overcloked ? if so set it back to stock settings and test.

Nutkin · 13 May 2017 at 21:26

Not overclocked at all,

Video to show temps when it resets after about 15mins on Furmark and CPU Stress

Update bios if not already done and all drivers also download mem test and check, is the psu new ?

I've read that the M2 drives can get quite hot, but you're not really using it in those tests.

have you tried safe mode?

Plec · 14 May 2017 at 09:23

What software are you using to monitor your temps, apart from Furmark?

Suggest, Core temp and MSI Afterburner if you're not already using them.

I have updated the BIOS with no change, I tried with GPU out and Justin CPU stress and VRMs on MSI barely broke 59degrees for an hour. Whereas with the GPU it hits 65 and shuts down and does its reset fit.

I'm wondering if the motherboard has a flaw in it where one of the MOSFETs isn't cooled properly by the heat sink.

Also thanks so much for the help guys, this is such a tricky one to diagnose as it could also be the PSU when it gets to the max fans etc ...

Have you tried the M2 drive in the lower slot to make sure the GPU is not making it overheat?

Quartz · 14 May 2017 at 17:26

For me, the prime suspect is the PSU. Perhaps a loose power connection. I'm not sure that overheating is actually the problem.

Something else to try is moving the GPU to another physical x16 slot.

Just because I got frustrated I have swapped out my 650w EVGA for a CX430 I had lying about, its a risky move but lets see if it pays off.

Quartz · 14 May 2017 at 20:06

You should be well within the TDP of the CX 430.

Nutkin · 14 May 2017 at 21:42

Quartz, nail head, 2 hours of gaming and then 40 mins on stress test not an issue. Just need to return the EVGA 650W and select a new PSU.

Any recommendations?

Quartz · 14 May 2017 at 22:52

I'm glad you found the fault, but I'll leave PSU recommendations to those who know a lot more than I do.

Super Flower 650W 80 Plus Gold - excellent quality PSU.

Actually Golden Green HX is somewhat question mark.
Original Golden Green serie used high quality capacitors, but then Super Flower "updated" it with cheap Chinese CapXon capacitors.

Without reviews of it it's hard to say what capacitor mix it uses.
And Super Flower obviously not having sent Golden Green HXes to reviewers isn't the best possible sign.

Thanks for the heads up - I didn't know a bit of ambiguity had crept into the range.

Nutkin · 15 May 2017 at 13:23

Ooh Dear I was looking at them as heard good things, this is the part I hate the gamble!

Real shame considering how Super Flower rose from obscure (apparently cheap) maker to top tier maker in short time.

Original Golden Green became fast popular also here in Finland because of being clearly cheapest high quality capped 80+ Gold PSU.
But I guess after establishing name they decided to use cheaper parts for better profit margin.
Even actual model code didn't change really any, but only got not always shown (HX) to its end.
Besides that other indentifier in "updated" version was change from fan wire guard to stamped mesh. (less parts and work cost)

Guess the old truth that if something is both good and cheap that fun doesn't last long still stands.
Same efficiency Leadex Gold 650W is in line with pricing of other known high quality capped PSUs.
