POST Issues

I recently had a flood in my dorm room and my computer was sitting in about an inch of water (luckily I had unplugged it before water got in). I bought a new power supply because that is the only component near the base of the case and just plugged it in, but whenever I press the power switch, the PSU clicks. I read that this means there is an internal short? Is there any way of diagnosing which individual parts may or may not be fried without having to buy a whole new computer or wait for months to troubleshoot with buying one component at a time? Thanks!

 

Specs (if they matter):

New PSU: Thermaltake 750W

Graphics: gtx 1060

cpu: ryzen 5 1600

ram: 16gb

storage: 240gb ssd and 1tb hdd

mb: rog b350-f gaming (the lights on the mb are present and there is an orange indicator light, so I think this part is fine)
