Thermaltake 850w to be exact.
Any help would be appreciated.
That is not very "exact" although it does narrow it down to 5 or more* possible models and 4 possible manufacturers. Note that ThermalTake uses other manufacturers to make their PSU's, they make none of their own. Is there any other model info on the box or PSU?
*It could be a discontinued model which I'm not counting
