I have a thermaltake smart m850w and I'm going to buy a GTX1080Ti in the next few days, is my PSU fine for a 1080ti or should I buy a different one? My Cpu is the i5-4690k.

It's quite an old power supply, not many manufacturers offered much better than a 3 year warranty back then. Seasonic had a some PSU's with a 5 year warranty. Then EVGA started giving out 7 year warrentys which seemed to start a warranty war with a lot of PSU manufacturers and vendors.

It has far more than enough power for a 2080 ti and is decent quality for the time. I would have no problem using it for a while longer.

It's based on the same CWT PUQ(B) platform as the current Corsair CX850M model. Corsair offers a 5 year warranty on their model whereas Thermaltake only offers a 3 year warranty.

It is way more than enough to handle your system running with any GeForce GTX 1080 Ti card.
