GTX 1080 faulty or not enough watts?

[aaronburgesss]

I've had this computer for a while now, and I've had the 1080 for 2 ish years, and recently I've been having some issues.

As my computer came up with problems with Windows 10, I ended up reinstalling windows on a separate HDD. A day or two passed, and everything was fine, and then I got this issue what really freaked me out the first time I heared it.
The display turns off, and the graphics card's fans goes to 100% RPM. I thought it was strange, and in the end I thought it was the extension I had it plugged into, so I unplugged it and plugged it into the mains, and the problem disappeared for quite a while.


A couple days ago, the same issue has come back when I tested Fortnite on epic settings to see whether I'd like the game or not, and I now have a Samsung 860 evo SSD, and my seperate 4TB hard drive that works seperately alongside it,with an intel i7, 16 gigabytes of DDR3.

The game works on the highest settings on Overwatch and Subnautica. It's happened once on No Man's Sky, but then after it happened once, it never happened again besides Fortnite.
I described my situation to a repair shop who lives nearby who is a microsoft certified technician, and he said that my graphics card is dying. So the question came up, is it my graphics card, that might need an RMA, or is it that I don't have enough watts?

I don't need 100% certainty, I'm going to get a better power supply and probably a new case as well, and I need something to ease my mind that it isn't something like the card, but the power supply not giving it enough watts. Here's a video of what happens to me on YouTube: (this is like 15 minutes into play of a game, not my video)[video="https://www.youtube.com/watch?v=ZNJNvZ3RtyI"][/video]

specs including make and model of PSU. Temps at load would be useful to know too.

Without info on your PSU, this is a moot conversation. As a 1080 owner, a PSU with an output of at least 500w is recommended.

Sorry, I'm new when it comes to asking for solutions.
FSP group inc, model no. FSP500-50AAGA
The temperatures for the card on intensive games are between 78-83c on max, it is a reference card mind you though.
I suppose if that wasn't what you were looking for, I could send an image instead.

Gut feel I think you are on the edge, it might only be rated at 30C, maybe 40C and beyond that it will behave badly.

In what way will it behave badly? shutdowns? I can't properly tell what's causing it, but it outputs 484 watts when I took a closer look myself, so I'm starting to believe more and more that this is the power supply not giving enough of a proper output than the actual card, if it isn't already shady already that they claim it to be 500 watts, when it's only actually 484 watts.

Without sufficient power, yes, you're going to experience a host of things like shutdowns or freezes. Even with a 500w PSU, you're right on the cusp of not having enough of a buffer or headroom. If you do decide to get a new PSU, I'd think about 550w-650w would be sufficient. It's better to have a bit more power available and not need it than to need it and not have it. Just get yourself a quality unit that's slightly above your power requirements and you should be fine.

shutdowns certainly, if is failing nicely, worst case sparking, fire and high voltage through the mobo. https://www.youtube.com/watch?v=bVN6eOEPins

It's common for cheaper PSU's to exaggerate their capacity, or to show a capacity but only at lower temps (high temps make it work harder), would I put FSP in general into that camp, probably not, but this is one of their cheaper units

Alright, thank you for that, I never actually ask for solutions. One thing before I end this off though, the thing my card does with the high RPM and display shutting off, is that normally caused by insufficient power, or is that unrelated or anything? I'd assume it's low power.

I'd be speculating and assuming if I said yes; however, based on experience and what you've described, it's certainly a possibility. As 13th has stated, asking more from a weaker unit unable to meet the demands is asking for trouble. Good luck.
