Earlier today i was watching a show on my pc when all of the sudden my pc shut off, i tried turning it on again repeadetly but it only got power for like a second before it went out again, only when i removed my graphics card could i turn my pc on again. But i don't know if the card is actualy broken or what there was no smell comming from it so i assume it hasn't shortcircuited. i am hoping someone could give me some advice to check out wether it works.as there was no strain on the card i am realy baffled by what is going on. my graphics card is a GTX 1080 btw.

You could go into MSI Afterburner, and turn down max power to 80% (or how ever low it goes) and see if that stops the crashing. If the game stops crashing, that points to the PSU even more.

Try to boot with integrated GPU (intel HD), See if it want to turn on. If not, then you can start to point your GTX 1080 for being the culprit.

Also check for PSU voltage drop using multimeter or just simply bring it to computer repair shop and let them check it for you.

Thanks for the reply! Currently i am running on the on board gpu and it works fine, however i did have issues in mass effect andromeda when it required a lot from the pc it would shut off and then turn on again. However i was able to use the PC doing regular things and playing most games with no problems now i can't even turn it on with the 1080 hooked up, but i wonder if maybe i take out some ram as i have 32 gigs if that would make a voltage difference and thereby see if the psu is the problem?

If you can boot with integrated graphics, and running games on it which means putting your PC into high-load situation that force your PSU to supply higher power for the CPU, then it suddenly turns off. I think you have problem on the PSU unable to supply needed power to your system or it just broken now. What is the brand and wattage of your PSU?

It's a corsair 750 watt. But with the 1080 as well as 32 gigs of ram and the 7700k processor i'm not sure the psu is able to handle it even though it did for a while as long as i didn't run anything too demanding but now i can't even turn the pc on with the 1080 inserted into the motherboard only without it. i belive the problem must be in the graphics card or psu, but i am no technical wizard so i don't know.

Can you borrow one's or your friend PSU and test it on your PC with 1080 installed?
Also check your GPU with another motherboard to see if your card is in a good condition.

I'm sure enough it's the PSU because when you put your 7700k into 100% load it will sucks 95w and more if you OC'd it.

Try to reset CMOS, reseating the RAM, and making sure if the card is properly seated on the PCIe slot.

Manishka1990 What is the precise model of your 750 watt Corsair? Could you please take two photos of your full motherboard, upload to imgur and share the link with us? I'd like to see if the 8 pin 12V+ motherboard socket is connected to the power supply. Just to be clear, your system is definitely shutting off? It's not rebooting? It isn't the display(s) only that is shutting off?

Please also tell me the name of your motherboard manufacturer and model number.

Okay so the picture should be with all power cables still connected as is? Yes i am 100% positive it shuts off my watercooling turns on for a second then shuts off and nothing happens i am not even able to turn it on again (for the second it runs) until i have disconnected power for a while and plugged power back in. Will see about figuring out the model of the psu need to remove a casing from the cabbinet to get to it.

Also since i was able to use my pc for almost a month before this happened can it still be the psu?

Also thank you guys so much for helping!

The 8 pin PCIe connector looks partially dislodged; in the 2nd picture from the top, in the upper left-hand corner. It could just be a strange photo. I would reconnect the 8 pin and 24 pin cables from both the motherboard and power supply ends and re-plug them back in. I would also unplug and replug the power cable in back of the power supply. If none of this fixes the issue then yes I would replace the power supply. Consider buying the model below:

EVGA G2 650
$89.99

I checked all the cables and everything is properly attached. The only time the problem arises is when i put the graphics card in again, besides that it works fine. Which is the only reason i'm not certain it's the psu especially since i ran with the graphics card for almost a month before out of nowhere it stopped but i will send the card in to be checked and if it comes back undamaged i'll try a new psu but i have to have one with at least 750 watt's though preferably above i think. Any suggestions?

Technically you would have been fine with just a 550 watt power supply. The only reason I suggested the 650 watt unit is so that you have the freedom to upgrade up to a GTX 1080 Ti or Titan X in the future. This particular PSU comes with a 7 year warranty. I personally have a 850 watt unit because I previously had two 980 Ti's in my build. The table above has conservative wattage figures because it assumes that reader may have a poor quality unit. Your AIO water cooler presumably only uses SATA power, and therefore has negligible consumption. Your i7-7700K and GTX 1080 have stock TDPs of 91 and 180 watts respectively; 180 watts for the reference card. My experience is that stock fan curves only consume 80% of max TDP on GPUs. With these figures in mind, you would be below the 50% efficiency curve on your power supply. But if more wattage makes you more comfortable then by all means proceed. I personally think it's more valuable to purchase a higher quality PSU with a slightly lower wattage, then a mediocre quality model with a moderately higher wattage. With that said upgrading from the EVGA G2 650 to either a G2 750 or P2 650 upgrades your warranty length from seven to 10 years. Either upgrade is currently a $30 increase in price on NewEgg.

The reason that I wanted to know the model of your Corsair power supply is to help determine the likelihood of your model being the culprit. If you have a Corsair CX then I would definitely swap it out for a better one before going through the hassle of RMA'ing the video card.

If I were in your position, I would:

Try the GTX 1080 in another system and see if it experienced the same problem.
If GPU worked fine in another system, then I would replace the power supply.

If trying the GTX 1080 in another system wasn't an option, and my power supply quality or age were questionable, then I would take a leap of faith and purchase a high quality power supply. I know that's a $100 investment, but I never compromise on the quality of power supplies. It's cheap insurance for protecting my build.

That's what I would do.

I'd definitely do testing in other machines if possible, but the PC shutting off while gaming is far more likely to be a PSU issue than anything else. Most hardware issues, other than a PSU, usually results in a soft crash, or system freeze. When they shutdown, it's usually the PSU.

I just did a check online on a site to see how large a power supply i should have and it said 750 at least and mass effect andromeda made my pc crash when the demand for graphics became too high supposedly because of the added power draw as far as i could read on the forums, but honestly i don't have a whole lot of experience with this type of problem. And i would probably order from a different site seeing as i am from Denmark this was just the only site i could find where i could get help :) But i will deffinately look into getting a better psu! The only fear i have from putting the card in another pc is what if the card damages that pc? i realy don't want to destroy one of my mates pc's because i have a problem :p But i don't know if that's a risk or if i'm just paranoid like crazy.
