Okay everything was fine . Till today when i installed my gtx 1080ti. Everything was fine when i installed the gtx 1080ti also i even played games on it for about 2 hours. And i started to play again 5 hours later and while gaming my whole pc just shutdown. And it wont power back on at all. No led lights from mobo , no fans worling . The whole thing is dead. Can it be the psu? Since it was working perfectly fine till i started playing games again? I also checked if it was the gpu so i used my old gtx 1070 and its still not starting up again.
Im using a 650 watt seasonic which should have enough power

well again, what do you have?

a 1080ti on a intel 115x platform, a 550 watt PSU should be fine but a HEDT and some AMD chips will use ~100+watts more and trip (immediate shutdown) the PSU.

btw, unplug the power cord going to unit? (then yes, plug in back in and hit the power button again)

Do this except when the power cord is unplugged, hold the power button for 30 seconds or so, then plug back in, wait 10 seconds and try again.

^YEP!

nice catch. also when installing the card;

lose a screw? (goes under mobo and causes a short)

connections firm?

maybe then try removing the card.

lot o' stuff to do.

yea i tried unplugging the pus and plugging it back in no response . the reason why i don't think its the mobo,cpu,ram is because it was running fine AFTER i installed the gtx 1080ti. i was browsing the internet , watching videos, playing games, and i was checking the temps. everything was perfectly fine, then i played games again 5 hours later and it was running fine again with no high temps and it just shut down after it was running everything fine. then i thought it was the 1080ti since it was the only thing i changed so i plugged back in my 1070 and again no response at all.

i just tried the paperclip method on my psu and the psu fan isn't spinning at all. Is this 100% legit to check if its dead? a paperclip into the green wire and the black wire right next to it and turning it on.

i'm convinced the paper clip test is accurate.

if everything looks proper, no idea why the PSU gave up the ghost.

is it still under warranty? but since the 1080ti uses ~80 watts(?) more than 1070, maybe think of 650 watts for reasons.

Sounds exactly like an overheating issue. Maybe the CPU? Can you verify that no LED lights are on, like the BIOS 2 character LED code on the mobo? If you can verify somehow that no power is being transmitted to the computer that would be great. And second, you would indeed smell something burning from the PSU if it died, in most cases. I never heard of a case when the PSU failed on someone and they didn't smell something burning. You might want to check the contact of your heat sink to the CPU. When something is related to overheating and you haven't done anything special mods to your computer, it is most likely the CPU because you literally place the heat sink on it yourself. Thus, check the contact of the heat sink to the CPU, and make sure the CPU fan is working.

One last or first thing you should try is let your computer COOL DOWN. Then see if it boots up. And I like the idea of doing a power reset; you unplug the everything from the PC where it can potentially draw power from. You wait maybe 30 seconds and then plug everything back in. I had to do this recently with a Asus 144hz monitor because it didn't like sleep mode or one of its capacitors maybe died out.

Edit: Ya, it would be insane if the PSU just gave up like that. And i second the idea of getting a 650W.

The paperclip test doesn't work on modern PSUs (like yours) with temperature-controlled fans.

My free diagnosis:

Your motherboard is a toasty wafer. As someone who uses MSI motherboards, I give you this word of advice: Never buy an MSI motherboard of lesser quality than an M5. They just die. Just like yours. Dead.

ASUS has higher quality boards for the same or less $$$.

Ya, I usually stick with Asus. However, about 1 year ago from now, I bought a Gigabyte-- the gaming 7 one, because it had the highest review count on newegg, and 6700k compatible motherboards were still in the "consumer testing" phase. I decide to gamble on Gigabyte. Didn't turn out well for me... just read the complaints about the unstable issues with xmp and lack of support they provide. Basically, their bios updates suck. They are helping a lot of people, but the other half either don't realize they have an unstable system or can't fix it. That's just pure speculation, but I'm all for Asus and Asrock, because they are notorious for great quality boards. Asus ROG is a great start. Hope you get ur chit working, op!

the seasonic G series has a silent mode for loads < 50% however it does not have a fanless mode that the X series has (s2FC vs s3FC, w/switch on the unit as usual).

so the fan should still spin.

Hmmmm.

Does it have an internal breaker and reset button?

Okay so i replugged everything in again and again no power at all. No leds from motherboard also. Completely dead.dont think it was overheating because i was monitoring the temps when playinf battlefield 1 and it was at 70c and all of a sudden shutdown. I purchased a new psu on amazon and its coming today(thank god for Same day shipping) and will update you guys today asap. Im hoping its the psu. If not can it be a dead mobo?

You can always sell the 1080Ti and buy a whole new PC for it's cost if it comes down to it.
You can test PSU disconnected, alone and measure it's output. That should tell you if it will even start at all.
Otherwise yeah who knows how much the 1080Ti is pulling on PCIe slot, the mobo might have said screw this and caved in. Or you have a lose connection somewhere, cables, GPU not all the way in the slot, etc.
I thought I had GPU installed once right too, everything clicked in and screwed, nope, it still had a way to go down into the slot after being clicked in... So recheck your connections everywhere and that you are using the correct cables and ports.

same day delivery of a PSU on a sunday?

though if so it might have came before now but . .

while you're at it, you might as well pull the mobo out and inspect it for burned stuff sniff test or whatever. then keep it out and put it on a non conductive surface to bread board it in case you have to trouble shoot potential problems. so yeah leave on the heatsink/cpu and ram. that AMD platform in your sig rig is still what you're using? need a gpu on that and also reuse that paper clip to short the power pins to boot up/beep.

is the paperclip method legit to see if its dead? because i just tried it again and the fans are not spinning up at all.

this is the exact psu and its 4 years old now .

https://www.newegg.com/Product/Product.aspx?Item=N82E16817151119

Specs are:

i7 6700k @ 4.5 ghz 1.323V
8gb ddr4 @ 3000mhz
5 fans total running at 100% speed
1 dvd drive
2 x hdd
gtx 1080 ti overclocked to @2000mhz core clock @6000mhz memory clock

If it was a dead MOBO, and my PSU was actually still working, would it not power up the PC at all? because i had a bad mobo last time and it did power up the PC but it wouldn't go to the bios or anything and the fans would still spin up because it was only a bad MOBO.

Also the only thing i changed was the GPU. Switched my gtx 1080 for a gtx 1080ti. thats all i did, i didn't touch anything else. and it was working perfectly fine also with the gtx 1080ti and played some games on it also, no artifacts and no overheating at all. then i checked if it was the gtx 1080ti because it was the only thing i changed,so i plugged my gtx 1070 and it still didn't boot at all. PC was completely dead.

I also tried to smell if anything was burnt, the psu has no burnt smell on it at all. The mobo has no burnt smell also.

We don't know. You need a multimeter to determine if it's the PSU or the board. Looks like current sentiment leans PSU.

is it possible that a PSU can die WITHOUT a burning smell? or does it always have a burnt smell to it when it dies?

okay so i sniffed the crap out of my MOBO and not a single smell to it. But i did smell my PSU again and it does have a slight smell to it, it smells like old dog piss( if anyone knows that that smells like lol)

Yep. Motherboard, too.

Alright guys im lost here now. I tested out my new evga psu with the jumper it came with and the fans spinned on the psu which means the psu is not dead . I plugged in the new psu and again no life at all. Completey dead, no led lights no fans , nothing is on. Can it be the motherboard then? I had a faulty mobo last time and the led lights would still be on the mobo, but no led lights on the mobo at all.

Ya, its the mobo. i'm assuming ur not seeing the bios splash screen. u also tried reseting cmos right?

Edit: actually you can see no bios splash screen and still have the mobo alive... happened to me this month. I just had to reseat my ram, because of hard shutdown that caused some corruption.
