Hello, I tried to run 3DMark on my PC but it shut off 3 times in a row mid benchmark. I did not check to see at what point during the benchmark it fails, but it shuts off (seems like power is cut) then boots up again. I am thinking the PSU is bottlenecking my system, but I am not sure. This is my first PC build and I am very new to this. Any and all help is greatly appreciated PC Specs: CPU: Intel i7 - 8700K GPU: EVGA 2080 Ti FTW Hybrid Cooler: EVGA CLC 280 Motherboard: EVGA Z390 FTW RAM: 2x8 GB G.SKILL TridentZ RGB SSD: Samsung 500GB 970 Evo Storage: 2TB Seagate BarraCuda PSU: EVGA 750 GQ Case: EVGA DG-77 Black

EVGA 2080 Ti FTW Hybrid + for normal ops should be fine. If you do not overclock the GPU and GPU Memory and keep the Slider at 0 for the Voltage and the Power Target at 100 can run the Benchmarks. I stopped recommending at least an 850 Watt Power Supply for the that Graphics Card EVGA 2080 Ti FTW3 Hybrid but others counter with your 750 is just fine. Are you using at 2 Separate PCIe Power Cables from your Power Supply to your Graphics Card? This is a Must regardless of what others may tell you.

When you say "Are you using at 2 Separate PCIe Power Cables from your Power Supply to your Graphics Card? This is a Must regardless of what others may tell you." Do you mean I need 2 separate 8 pin connectors going from the PSU to the GPU? Right now I have one cable that is connected by a single 8 pin to the PSU and splits off into two 8 pin connectors, both going to the GPU.

Correct Two Separate Cables. Do not use the Two Pigtails from One Cable, Use only One of them from Each Cable.

I wouldn't call it a bottle neck, EVGA recommends a 550w psu with your current set, 650w if overclocking. I'm not sure how much headroom their power meter gives you but a 750w should be fine. Usually, random restarts under load is an unstable power supply so if it continues after you try 2 separate cables, then I would suspect your PSU is bad. Test with another PSU if you have one available and you will probably have to set up an RMA. Remember, with computers, it can be anything and everything!

Requirements
- Minimum of a 650 Watt power supply.
- Two available 8-pin or 6+2pin PCIe power dongles
- Total Power Draw : 250 Watts
They need to update their Power Meter then, it says a 550w PSU is sufficient for a 2080 Ti with his current gear or 650w if overclocked. Hopefully, using 2 cables will fix his issue like you suggested.
Both values are correct, even if the Power Meter recommends a 550W. NVIDIA recommends a 650W minimum for an RTX 2080 Ti, which is what we list. The Total Power Draw is 250W, unless you're overclocking. Either way a 750W power supply should be sufficient, unless there's an issue.

Hmm I changed out the cables and its still shutting down. I dont have a different PSU to try, but that will be my next step to figure it out. Thank you so much for helping me out with this, everyone!

If you go into your motherboard BIOS, go into the Hardware Monitor (or similar name), and report what your +12V, +5V (if there), and +3.3V (if there) are listed as. Come back and let us know what those read at. Don't use software from within Windows.
