Recently, I bought pc parts to build my first pc build. Everything went well, and my pc booted up and all. There is however one problem, and that is the AC power cord that connects my PSU to power. The cord that fits into my EVGA 600W BR power supply doesn't fit in snug, and wiggles up and down. My computer would shut down even if the cord moves a bit, and needs to hit a sweet spot in order for it to stay on. Any suggestions on what I can do? Can I try to use another AC power cord, such as the one found in my very old computer? (From 2006, prebuilt computer). I pushed the cord all the way in, but still wiggles. I dont think the prongs are bent either, but I have to double check later on.
