plug something else into the outlet to make sure it is on, if it is you likely blew one of the fuses in the power supply

Try "paperclip trick" ....after checking that PSU switch is on and both ends of cors are plugged in.

1. disconnect all power leads from PSU to MoBo and devices. Leave a fan(s) connected to a molex.
2. use a paperclip to short out pinouts 15 and 16 on the 24 pin connector.

If fans don't spin, likely PSU took a dive.

Unfortunately there may be other problems, I've seen a power surge take out an array of different components without rational.
Your best hope is that it is just the psu, unplug all main power cords from motherboard and data cables from harddrives, leave case cables intact and one power lead to a harddrive, see if fans come on and harddrive spins.
If not, you need another psu, while it may need a fuse it's dependent on where the fuse is placed in the circuit as to whether other damage to psu occurred. Newer power supplies with active pfc and overcurrent/overvoltage protection would just shut down protecting everything after it.
