Pc randomly shuts off

[Seanh1818]

Idk why this just started happening. Only thing I can think of is that my 460w psu from my alienware isn’t enough for my pc. Any ideas? Did it once and wouldn’t turn back on then just happened again and it just restarted and seemed like it double booted 

[emosun]

Did you want to tell us anything else like what alienware it is or what the specs are or what the temps are or what diagnostics youve already done

Not an Alienware just the psu. All my temps are normal and I think it only happens when I have games open 

[emosun]

With a 1080 in it yeah whatever alienware psu youre using isnt going to be good and should be changed anyway. After its changed and you know the hardware is reliable you can start software diagnostics

460W is not enough for a GTX 1080

PSU change time as come, anyway what is your CPU running at 2.8GHz could also be a bottleneck issue even after the fix...

Nvm you got a 8400 all good lol

The minimum recommended PSU for a GTX 1080 is 500W and you're using an old PSU from a Alienware so the issue is obvious. Buy a new 600W 80+ bronze PSU from a good manufacturer like Corsair, EVGA or Seasonic.

Should consider a higher frequency on your RAM 1333MHz is low...

Ok, for the PSU you should consider upgrading after all it’s what’s powering your PC.

Has nothing to do with their issue

Yeah I wasnt refering to the issue was just an observation shouldve clarified thanks!

Alienware PSUs aren't sold retail. How did you end up with an alienware 460w in a non-alienware PC?

 

Without knowing the actual model of power supply can't really give you any more information. Can you post a photo of the label on the PSU?

Does it at least have the appropriate PCIe connectors for the GTX 1080 or are you using molex to PCIe adapters?

It is, as long as it's not a poor quality PSU. GTX 1080 is only 175-200w card and the rest of the system with an i5 on a locked motherboard isn't going to draw much power. A good 450w would be plenty.

1333mhz = effective clock of 2666mhz since it's double data rate (DDR) memory.

That is also the fastest speed their H310 motherboard supports. It's not related to their issue.

What I can't really wrap my head around is why it's showing that the 1080 only has 4GB of VRAM. Maybe it's just Speccy being Speccy?

 

Regarding the actual topic, I wouldn't imagine that Alienware's PSUs would be amazing or anything in terms of quality, 460W should be enough normally if it was a good quality unit, so that's probably it.

Haha oops didnt think about that Im used to seeing the full value but as I said above I wasnt relating to the issue but just an observation

Doesnt GDDR mean the same so 2x 4GB = 8GB VRAM?...

Nvidia recommend a 500W, but yes I agree a good 450W PSU should be enough, but here it's not the case his using a cheap PSU that was in a Alienware PC.

No you're talking about capacity, you only double the speed.

Aaaaaaaah haha now I get it so theres no reason that it's only showing 4GB (excluding weird software issues)

I didn't even notice that. Like you said, speccy isn't always accurate...

But it might also be a fake GTX 1080. 

 

@Seanh1818 can you please download and run gpu-z and post the results here.

We don't know what PSU they have yet. Just because it's from an alienware PC doesn't necessarily mean it's bad.

Usually prebuild PCs have cheap PSU to keep the cost down. Pretty sure the quality is not up to a Corsair, EVGA or Seasonic 450W 80+ Bronze PSU.

 

We are not talking about a business or a workstation OEM desktop.

Spotty said that it was a Mobo limitation...? That could be the problem.
