To UPS it or Not to UPS it…

Uninterruptible Power Supply as they call them (or UPS in short) is a nice device. In contrary to common beliefs, it’s not that expensive but is very, very useful. I am a firm believer, that it should be in every home, where the owner of the expensive or fragile equipment, wants his pieces to last longer. I wasn’t like that from the beginning, I was actually quite opposite… “Why do I need it?”, I’ve asked myself many times… With time, using various bits of Audio Video Receivers, many different PCs, Printers… I found that, since I am using it, there is no sudden resets, restarts of my PC or file server, it is just rock solid… Also, it always annoyed me when I’m connecting power plug and I can see an arc sparking from connection… No more…

UPS

This unit (1300VA Management UPS PW-4130M) is quite simple UPS and works well for me, but was the same problem with both units I have at home: noisy fan, always on and amount dust accumulated inside after whole year…

Remember, when opening any UPS, always be sure that it’s switched off!!! Also, it will have a battery, so if you accidentally switch it ON it will POWER UP. You have been warned. I will not take ANY responsibility if something will happen to you. Just be careful and DO NOT touch anything inside…

Problem is quite simple to remedy: replacing the fan with something much quieter and while you at dismantling the case (hold by 4 screws inside of plastic feet and smaller screw at the bottom of front cover), you can vacuum inside. When installing your new fan, you can redirect it from blowing outside to actually blow inside of case AND install dust filter outside of case like I did. Now it’s quiet UPS and I can clean dust without opening case.

Just remember to clean every so often…
