My office PC's power supply has been really annoying me for the longest time. Whenever I cold boot my first thing in the morning, it emits this really loud fan sound. I have to slap the power supply a couple of times everytime to lose the sound. Once that loud sound is gone, what remains is the high-pitched whining sound (kinda like a small jet engine turbine) which drones on for the rest of the day.
Well, that high-pitched sound has made me reach my limit today. I really could not think straight with that annoying sound. I was suspecting that perhaps this sound is from my CPU's fan. So I called our tech guys for help and they diagnosed the problem to still be related to my power supply.
The guys replaced my generic power supply with a branded one from HEC. This power supply costs about Php3k, but let me tell you -- its worth every peso! I don't recall my office room to ever be this quiet! Its like there's no PC running. Sure, a generic power supply costs only between Php500 to Php1k. But the lost productivity is probably worth more than the Php2k differential.
