I recently finished tidying up my cable management in my PC and it powered on nicely without any issues. However, I forgot to plug in my case fans like an idiot. After a bit of toying around with some cables, I plugged in a cord to my PSU with a female molex becuase the molex with the case fan cable was male. After doing that and turning it on, I could smell a strange burning odor coming from the CPU/RAM area. Like the idiot I am, I let denial get the best of me after I panicked and turned it off and unplugged the power cable because I ended up turning it back on only to have a small puff of smoke come from the same area where the smell originated from. Between the RAM and CPU. No need to call me an idiot because I've been doing that for about an hour now before I got past my shock and made this post.
