Hi all,

My PC has been recently shutting off playing PUBG, it could happen at the beginning/during/end or not happen at all, its a strange one. It doesn't BSOD,, its as if a power cut and reboots automatically.

I'm thinking PSU but don't want to rush into sorting a new one until I've gone through other checks?

I removed both CPU and GPU overclock to see if that helped and I thought it did, but it just hard powered off there.


Main specs:
6700k
Z170 G1 Sniper
16GB GSkill Trident Z
AMD Vega 64
BeQuiet PowerZone 650w

Any help would be appreciated.

Thanks

That's cheap capacitor PSU.

Have you tried Wattman's Power Save profile if it changes things?
Also Windows tends to default to rebooting instead of showing error so disable that.

Checking heat?

I've seen my PC just turn itself off from hitting it's max temp.

I've the power saver option on Wattman instead of balanced. It hasn't crashed during PUBG for the past hour.

Windows is set to not reboot all the time, system completely shuts off without BSOD still.

@Begbie Under custom loop, temps are high 30s low 40s during gaming.
 
I ran Intel burn test and valley with Wattman profile set to turbo, no issues at all. Strange!

Does everything point to PSU?, or is there anything else I should test?

If the PSU isnt up to the job could someone recommend a few ?
 
prob your psu how old is it ? it's a bit low for a vega is the 6700 oc ?
small case ? not to many fans ? is your vega on 2 different power cables ?or just a split one ?
I'd be looking at an 850w for that system

PSU was bought in November 2013 so still under warranty actually.

The 6700k was clocked at 4.7ghz and the Vega was clocked 1680Mhz Core and 1100mhz Memory.

But the shutting off continued even when I took overclocks off. I did get a good 90 mins of pubg without power loss but that was with the power saver AMD profile.

I'm using a ThermalTake Core P5 so it's a big open case, and it's fully watercooled with 4 SP120s on the 480mm rad. Vega is on 2 separate PCIE cables and not split.
 
The primary cause is most likely the PSU. I've just fixed today exactly the same kind of problem in a clients PC by replacing the PSU.
 
I've contact BeQuiet about the warranty.

Should I just get the replacement from them or would a newer 850w PSU be better. I see a lot of love for the Seasonic Focus Plus 850w.

@pastymuncher Sorry for tagging you in this but your knowledge of PSUs would help here.

When I bought the BeQuiet it seemed to have great reviews on the likes of kit guru. Is it actually any good?
 
nowt wrong with your 650 it's just not enough ...
vega 64 290-350w 6700 oc 95-120w motherboard say 50 ish then all your bits and bobs .. takes you over.... the poor psu is screaming daddy don't hurt me ....
 
Does the intel burn test load just the CPU or the GPU too? I'm assuming the graphics card will draw more power under load, or the combination of both CPU and GPU is causing the instability.

IBT loads CPU , Valley loads GPU. I ran them both at the same time. Didn't power off doing that.

I’ve had the same problem with a build in the past. Passed every test I threw at it. Turned out to be the connection that actually gave the mobo power. I assume heat loosened the connection by expanding the connector and the only way I managed to fix it in the end was a new psu.

Quite specific, but my only suggestion would be to check the connection between the psu and mobo.

When stress testing your cpu your gpu becomes under-utilised most likely.
That’s probably why it’s not shutting down in that scenario as your gpu in the most power hungry component.
You would need to tax your cpu with something lighter than IBT and lower priority of your cpu stress testing software and upper priority of the gpu stressing software until both gpu and cpu are maxed out.
 
Just bumping this.

I used HWinfo to monitor power draw of GPU, it didn't exceed 253 watts. Ive a 650W BeQuiet PSU surely I shouldn't be pulling enough power to shut it off during gaming? Can't seem to monitor the CPU power draw though.

Edit: Ran IBT and Furmark, shut off immediately. Points to PSU so ?

Edit 2 : CPU is at stock running IBT, Ran Furmark on Power saver power profile in Wattman which it ran away as normal, switch profile to balanced and boom, hard powered off.

Am I pulling more than what PSU is capable of? Or is the PSU defective.

Thanks

ok go to my last post ..
and what was hwinfo saying when it crashed ?3XX w
just get a 850 psu problem solved it may be the 650 cant do the amp draw ? or it could be just watts .. either case you need a 850 .. your own testing is telling you this

It was reporting 253w for the GPU.

I'll purchase new PSU so. Thanks for your help

If it was that properly even as new.

PSU is last part to go for cheap in high end PC.

Get something like Seasonic Focus Plus.

I didn't believe it was a cheap PSU when it got all good reviews when I read them before purchasing. I'll pick up the Seasonic

If review doesn't have "autopsy" of PSU then it's no review.
That drops likely huge majority of them to previews at best.
And then lot more don't pay that much attention to component quality.
Instead of generic Teapo or even worse C(r)apXon and such capacitors you want those from (Nippon-)Chemicon, Nichicon, Panasonic and Rubycon.

Low quality capacitors are simply one of the most common reasons for electronics dying faster than expected.
So would be actually better to have below best performance and quality parts than best performance but lower reliability parts.

Seasonic basically uses only Chemicon capacitors, with occasional Rubycon thrown in likely when Chemicon run out of stock.
Most manufacturers aren't as precise about that.
And most PSU names aren't even actual manufacturers.
For example BeQuiet and Corsair make no PSUs, but order their PSUs from multiple manufacturers with some customizing (like fan/colour) and their sticker on top.
