Attempt 1: If you "heard a pop and saw smoke from the motherboard" then you shorted something or blew a critical capacitor and wouldn't be able to fix it so you did the right thing by getting a new one. However, things normally don't go pop just for a random reason and it's likely you shorted something so the question is what shorted it? Attempt 2: I suspect your new case is the fault here. Is there something metal that's contacting from the case to the back of the motherboard? If that completes a circuit then all the power is drained to ground because the power supply exterior itself is grounded which is connected to the case to avoid you electrocuting yourself. This probably explains why the power supply is fine if it is run in isolation.

The fan is failing and there is nothing you can do save replacing the fan (a pain in the ) or buying a new graphics card. You might be able to RMA it but it could be just considered wear and tear.

If it is auto rebooting it is likely either CPU temperature or power supply collapse. You can check CPU temperature by monitoring software. You can also open your case side panel to reduce the temperature which might delay the crash. If it's voltage collapse you can somewhat test this by removing one 1080 Ti and seeing if the system runs without problems. By taking out of SLI do you mean taking one card out or disabling SLI? I'm not that familiar with SLI power draw when enabled/disabled.

The other suggestions are great but the simplest solution in the near term is to open up the PCIe slots on your case to enable more air circulation in the case. Alternatively, open the side panel of the case. You are compromising dust but that can be mitigated with regular compressed air maintenance.

I had this issue with MW and traced it to not having enough memory that it was swapping to my HDD - very difficult to find. I had 8 Gb at the time on my old PC so I am getting a new one. My PC ran it fine when MW was initially released but they kept adding features to it and it was using more RAM putting it into swapping territory. So my advice is to get more RAM. Also, FYI, if you're playing an FPS you want to get at least a 120Hz monitor. You will be less tired after playing and play better.

Red Orchestra 2: Heroes of Stalingrad. Steep learning curve but very fun once you adapt.

This is correct. In simple terms, small capacitors are used for decoupling/smoothing high frequency signals because they can discharge fast enough to follow the signal. Large capacitors are used for decoupling/smoothing lower frequency signals because they can accommodate enough charge to smooth the waveform. Depending on time and engineering expertise, they may have not done calculations and enough experimentation to determine the optimum mix of capacitors. -EE Ph.D.

Nope. Every single time I managed to find one the cart glitched out on multiple websites.

Thank you! Thanks - that's good advice. Thank you. I'm not a student any more but I've spent enough time at school that I feel naked without Word/Excel/PowerPoint at home to work on things like hobby data analysis, resumes, and presentations for interviews. Thanks - I'll get the Samsung.

Budget (including currency): none (USD) Country: USA Games, programs or workloads that it will be used for: Primarily high frame rate FPS online vs. humans gaming (I used to be a competitive player), lately enjoying Unreal engine games like Red Orchestra 2 and Insurgency Sandstorm Other details: This will be my 3rd build (1st in 2003, 2nd in ~2012) and I need it since my current PC is 8 years old (i5-3570K-based with a GTX 1650 since my GTX 570 died last year). I am looking to go all in on a Nvidia 3090 build because why not - I can afford it for the first time in my life. My goal is a close to top-of-the-line build for gaming without going too over the top for marginal gains because of diminishing returns, an example would be the Intel Optane SSD. I favour longevity of components since I typically keep my computers for a long time between upgrades. Activities will be gaming at high FPS and personal office. Quiet and cool operation (since temperature and longevity are related - those pesky high energy electrons causing traps!) and no light gimmicks (if they are inside the case with closed panels, no problem) would be ideal. I prefer air cooling since I am familiar with it but am not totally averse to water cooling if the benefits are substantial. I plan to keep my current monitor BenQ 2420T 120Hz display, at least initially, while I research displays and wait for the nVidia Reflex displays to launch. I'll maybe also consider 4K/VR later. I have all peripherals. One special consideration is I plan to move my optical drive over from my old PC to my new one since it is a UK region drive so I need space in the case for an optical drive. The 10850K looks a reasonable alternative to the 10900K. I'm not considering AMD. Thank you for your advice and time.
