Donate money in the name of God if the only component in your system that was damaged was the power supply alone.
If the psu is under warranty, do the needful, but see if you can get a standby psu and test the hardware. If its not, get a new one- or swap it with your GS800- and see if the system is booting. If yes, see if all the stuff is getting detected and working. If anything doesn't work the way it should- or doesn't even power up- well, prepare to swap and test each and everything.
