So... I "finished" building my computer, I turn on the switch and nothing happens! When I first plugged it in and tested it a fan started for 1 second and I heard a faint hissing sound from the psu, like, really faint. and nothing after that. I'm really not sure what to do :( I looked on te instructions for f panel connectors and they're all good. I'm thinking It's the power supply but idk, I bought it brand new from the store!

Really could use some help, i hope it's not all fried somehow or 600 bucks down the drain :(
