No power from outlet to system

Hello all! My Ps4 slim has stopped working on me. I recently moved, and not to long ago, my Ps4 died. It does not have a power indicator light, nor does it make any sound when plugged in. I opened it up and found a lot of roaches in it. After looking around on google, I've come to the conclusion that my power supply shorted out. Is there a way to fix this, or do I have to buy a whole new power supply? If I have to buy a new power supply, what would your suggestion be, to reduce the risk of roaches or other bugs causing another short?
