underpowered psu Underpowered PSU

[OxyAcetylen]

After two month of hard work finally saved enough money and bought a 4k monitor and recently noticed that when playing game "PES2018" at full resolution my PC randomly shuts down, it never happens or happened before when I had full-hd monitor, which is very likely is my underpowered PSU that causing it, otherwise at lower resolution the game works without any problem. 

My question is, could there be any way to control your power supply consumption?

 

My system:

"Asus Sabertooth 990FX R2.0"

"AMD FX 8350 black edition"

single "Asus GTX 1080 strix"

"4x HyperX Fury DDR3 1866MHz 4GB" (all four running at 1333MHz)

"Acer 28" xb280hk monitor"

"2x 120mm case fans"

"cooler master v8 gts" heat sinker 

"EVGA 550 GS" PSU

"Microsoft Windows 10 pro"

normal keyboard and mouse

What do your cpu temps look like. Your cpu is a huge bottleneck and may just be overheating leading to a shut down. My brother in law had a similar issue with almost an identical set up.

550W is plenty for that system. Your issue lies elsewhere.

That shouldn't be eating up anywhere near 550W. Is it only that one game doing it?

cpu temps is around 45-50 and stable, there is not many task running in the bakground

Yes, actually i have not tried any other games at that resolution but in my previous monitor at full hd other games worked fine.

Try some others. If it is just that one game, poke around online and see if anyone else has had similar problems with it. There might be a solution in the game's settings that you don't know about yet.

 

If it's happening on more than that one game, try downloading DDU, doing a full wipe of your 1080's drivers, then reinstalling a fresh copy of the GPU drivers straight from NVIDIA.

I'll try them.

so you don't think this problem is due to low power and there is something wrong with the system in the software? if that is so, I have to say that was very great to know.

I'm not going to ignore the possibility of bad psu.

 

PES is very CPU bound, and it is possible with that CPU and that motherboard, it's probably using too much on CPU rail alone.

No, I sincerely doubt this is a PSU problem. That 8350 uses up 125W, and the 1080 uses 180W. A 550 GS should handle it. The possibility of a bad PSU can't be ruled out, but it's only happening in one circumstance in one game.

So you mean that CPU can't handle it or it take to much power that makes the PSU to go under powered?

the latter.

 

look up for your PSU description on 3.3v rail and 5v rail.

example:

 

with that example, if CPU using more than 90w than it will have problems, even though it's rated 400w (combined)

Then I have to try different settings and see if it does work. Right now I'm playing Dark souls 2 at full resolution and it keeps going without problem, and I have to say that the game looks gorgeous at high settings

so my cpu which using 120W can't handle it?

got a shot of my psu:

CPUs take their power from the 12V rail. The 3,3V and 5V rails are barely used by the PC

isn't the mobo that uses the 12V rail?

 GPU Temperature??

And everything uses the +12V rail.

+3,3V and +5V Rails might be used for chipset and memory - under normal load around 2A, +/- 1A...

GPU right now at ideal temp is between 44-45
