EVGA GTX 1080, pc restarts during games.

[nozirah]

I recently purchased an EVGA GTX 1080 Superclocked 2 and when i try to run benchmarks my computer almost instantly reboots, and when I play games if I set the resolution to 3840x2160, it's an instant restart as well. If I play in lower resolutions it will work for a while depending on how low, but ultimately has the same result. I suspect it's a PSU issue but would like to be sure before replacing it, any advice would be appreciated.

System specs;
Motherboard: MSI X370 Gaming Pro
CPU: Ryzen 7 1700
GPU: EVGA GTX 1080 Sc 2
Ram: 16GB DDR4 3200mhz Corair Vengeance
PSU: Thermaltake Toughpower 750w Cable Management.

Yeah, replace the PSU with a quality unit and you will be fine.

Probably an obvious answer, but I'm assuming you have the power going into the graphics card? It sounds like your PSU is bad. I have a EVGA 750w and it works just fine with my 1080 FE.

I agree, I have built 200+ systems over the years and every time I try to give Thermaltake a chance they have let me down. Regardless of the efficiency certification on those units I have seen them fail long before they should. I have had the best luck with Seasonic, EVGA, and higher tier Corsair PSUs.

This is currently on sale and would fit the bill for your current setup. https://www.newegg.com/Product/Product.aspx?Item=9SIA6ZP3R88399&cm_re=evga_power_supply-_-17-438-017-_-Product
