Any help would be greatly appreciated!

Power Supply is a Seasonic focus plus 650 watt

My specs are:


i5 3570k (speedstep) (not overclocked)

16 gb ddr3 ram 1600 mhz

msi 1080ti gaming x (boosts to 1900 mhz sometimes O_O)

a high end sound card / soundblaster zxr

a high end wlan card / asus pce - 68

2 ssds

1 usb 3.0 7200 rpm hard drive

1 high end mechanical gaming keyboard (g 710+)

1 high end mouse ( g900 )

4 120mm fans

1 140mm fan

1 cpu fan 92mm
 
Solution
Yes, quite easily. The manufacturer's website says

POWER CONSUMPTION (W) 250 W
RECOMMENDED PSU (W) 600 W
POWER CONNECTORS 8-pin x 2
https://us.msi.com/Graphics-card/GeForce-GTX-1080-Ti-GAMING-X-11G/Specification

That PSU exceeds the min. requirements. I instead chose the Seasonic G- Series 650W 80+ Gold PSU. The Focus was closer to $90 and my PSU was only $69.

Why does it only reach 1900MHz? It should be closer to 2000MHz. I keep my EVGA 1080 Ti FTW3 Hybrid under 56C because that is when Nvidia's GPU Boost 3.0 starts throttling the OC. Don't get me wrong. I am not saying your card is thermal throttling. An overclocker knows his or her PC very well and some push their PC's over the edge and the system crashes. They reboot and try...
Yes, most 1080ti card pulls maximum 375w from mb and 2 8 pins, the rest of your system pulls about 200w maximum. And that’s under the worst scenario, normally similar system pulls about 300-400 under benchmark load. So yea the psu is fine.

I am not saying your card is thermal throttling. An overclocker knows his or her PC very well and some push their PC's over the edge and the system crashes. They reboot and try again. Nvidia doesn't have that luxury and because of that the OC needs to be rock solid. It will automatically OC your card but I suspect yours is getting too warm for its liking.

It throttles in 12MHz increments at anything above ~55C (or something like that.) Read somewhere on EVGA forums. While my EVGA SC2 stays relatively cool at around 69C, it still isn't at full speed all the time.
