hello
i have not posted here in a while but I am having some issues related to my 1080Ti FTW hybrid in a mini ITX build I updated for my living room gaming.It was running an AMD 480 GPU and I decided to swap my Game room rig 1080ti into ths build which s a Core V1 case.It was a big challenge to get especially the PCE e cables to fit and had to make big use of my dremel tools but anyhow, it worked packaging wise.
Problem is that I am getting hard crash, PC reboot without warning even with the card at stock settings if I play 4K games in High or very high settings or even only in HEAVEN 1080p benchmarkng if run for more than 15mins
Rig is made of a Z97 motherboard, the CPU is an I5 4670k OCed at 4.4Ghz and PSU is a Bronze 500W model.The card is powered through 2 separate PCI e cables from the PSU modular slots so each lane feed 1 port on the GPU, its not single lane split in 2
I see he power use of CPU/GPU/MB combo around 400W at really max use so 25% safety against my PSU rating.
I control the GPU radiator fan through spedfan, the PWM cable from the card is actually pluggedu in a PWM controller on the motherboard so its a different setup from the stock design that EVGA set
If I reduce the in Game graphics settings, the PC will run for longer but will do shutdown eventually. If I UV/reduce the Core/memory Frequency, it seems stable but of course gaming become crazy choppy.
I dont see n AB or HW basic monitoring either CPU or GPU overheating at all, CPU remains below 60degC and the card around 50degC so I am thinking its a voltage/ampere i delivery ssue but I have no idea how t troubleshoot this either with these monitoring tools or Windows crash dumps.
I ma thinking to buy a new PSU with higher Wattage and maybe Gold certified but I would like to avoid spending cash if I ca fix the issue another way.
any idea and suggestions for troubleshooting much appreciated
thanks

my sig rig is the one I was using the card in my Game room, PSU gold rated at 650W which I realize now is above the requirements Nvdia advise to run this GPU so it seems I had been optimistic to move the card ina rig using a Bronze 500W PSU model but yes, if some people here oculd confirm my thoughst about the PSU being the culprit and maybe advise a good SFF PSU that would replace my existing one, its appreciated

Definitely a psu issue. Time to get a better one.

Swap out the PSU to confirm prior to spending your cash. EVGA makes good power supplies. https://www.evga.com/products/productlist.aspx?type=10&family=Power+Supplies&chipset=650+WattsPick your poison and your price point.

yes i will invest in a new PSU indeed but evga ones are not cheap over here in Japan.
I am running the card at 90% power and std memory clock and it seems stable for now, fps are not too bad for 4k gaming so I will leave this for few days before replacing it with a new one because I am guessing the PSU is being hit hard so I dont want to kill it so I can be able to maybe build a PC for my daughter with it
sorry if I was positing this in the GPU section, clearly a big oversight from my side about the PSU capacity to deliver what the 1080Ti needs

There are many good PSU brands available such as Corsair, Seasonic, EVGA so look around for the best price.

What I meant was swap out the PSU in your other system to verify the PSU is the problem. I say this because USUALLY when you reduce the power target or the GPU frequency, and you are more stable, the issue is with the GPU not the PSU. In your case with a marginal sized PSU, it is probably the PSU. But it would not hurt to swap in your other one if it is not too much trouble. A quality PSU is not cheap and the worst thing to go cheap on is the one thing that if it goes bad, can take out the rest of your system.

hello. I got what you were saying.
the thing is the card was working very fine, good OCer very stable, in my rig with the 650W Gold rated PSU so I dont see how it would have lost its OCing and stability just by getting into the other rig, unless the 500W Bronze PSU that is in there is creating trouble as I think it does.
I will order a decent 650W min PSU from Amazon and swap it with the 500W one to see if problem is gone. I still can send it back with their 30day return policy if that doenst fix the problem
Next would be the MB to investigate but I dont want to think about that......

I bought and fitted a FSP PT 650w this weekend and problem fixed as suspected again sorry for the emotional thread i shouldhave thought about power supply to the card
Now i need to rework my overclocking from scratch because i lost my AB profiles after an update
Is the new EVGA OC tool any good in comparison?

Are you using the voltage curve method or just using an offset? If you're getting 2000mhz stable under load at operating temp, you're doing good.

Good deal. I'd recommend msi afterburner.

Card was doing 2075mhz so +75mhz from stock on core and +500mhz memory in my Atx case with 2019 drivers Thermals were in high 40 to low 50s degC but it was to push graphics at 5760x1080p resolution (triple screen setup) but now it has to run on a 4k Tv and in a SFFBcase so i expect more stress on the card read less OC potential And yes i have been using AB voltage curve user for years since maxwell gen but i saw new features in EVGA X1 tool hence my question. Is there a good OC tutorial guide with this tool that people recommend?

They function identically as far as using the voltage curve. The case isn't going to matter, your temps is what matters. If you keep the same temps on the GPU, you'll get the same clocks. Your first temp bin is all way down around ~30C. The 'auto magic' overclocking feature is fer dummies...

Let me assure you, it's very unlikely a PSU issue. I had the same issue with my card and found that reducing the power limit to 90% made mine stable. I contacted EVGA and it's a common problem, the card most likely has an unstable overclock from the factory (GPU BOOST) and it's boosting to unstable limits. It could also be a VRM issue on the card itself, my suggestion is to RMA the card. I had mine in a rig with an 850 watt gold rated PSU and had the same issue. Even when I upgraded to a 1000 watt platinum rated PSU in my brand new AMD system, the problem persisted.
