So i was building my computer, I forgot to unplug the power supply and when i was getting ready to install my mobo, the psu/psu wire/antec 300 backpanel caused a huge spark. That spark was extremely quick and i thought i fried the psu. When I turn on the psu, the psu powered on fine and the system, 4 hours later, it completely done and everything is fine. This moment really scared me. First time I used a ocz z-series 550watt or any ocz psu for that fact, I thought i was screwed but I guess I was really lucky or psu's awesome
