The power supply in my main computer has been really noisy, almost like the fan was misaligned. I could tap it and it would stop for a few seconds then start back up. I got tired of it so I pulled out the power supply and let it run like that. It worked for about 2 days until it went out with a big POP!
The replacement just came in today and everything works just fine, fortunately. I gutted the old one and gave my macro lens and photon lights some good times. Sure enough, the CompE in me started figuring out what all everything is.
The 104 on the left denotes a .1uF capacitor. Just to the left of that is a larger 4.7uF cap. There's a couple resistors in front (but you can't identify the colored stripes due to the red light. The KIA393P IC spotlighted in blue is a dual comparator. (Thank you google.) Just behind it and directly in front are two more caps. It sure is dusty in there!
