I noticed that my home computer system was experiencing some power-related problems such as my speakers switching off suddenly or my AVR making crackling sounds.
	I diagnosed the problem and zeroed it down to my aging AVR. I think it couldn't handle the load of my PC, speaker systems and other peripherals.
	So I decided to purchase a UPS. Haniff and I went to Midvalley Megamall and I found a UPS which I liked - a 650VA Liebert. It's very compact for its power rating, and very robustly built.

 

However, we hit a small problem. My speakers, the Altec Lansing ADA880, uses a power cord that is embedded into its subwoofer amplifier. What I mean is that the cord cannot be disconnected. And since the UPS only accepts a particular power connector, we had to find a special adapter. Haniff and I searched around in Megamall, and by good fortune, we discovered a DIY shop called Ace that actually had this magical adapter.   With this adapter, it was possible to connect a normal three-pin plug to the UPS.

I was so happy that I got all the required parts. Once I got back home, I connected all my computer equipment to the UPS, and it worked perfectly the first time.

 

	After a night's worth of recharging, I retested the UPS, this time by switching off the mains supply, and it immediately provided supply to my PC via its battery.
	The Liebert UPS has a few other nice features: - Warning red light and sound beeps when it goes into battery mode. It has three battery-powered outlet, and one surge-protected outlet. It has a circuit-breaker that protects the UPS in case of overload. It has lighting-protection for phone lines too, which I use to protect my ADSL modem. It weighs only 5.6kg.  And it looks pretty cool.
	Overall, I am pleased with my purchase of this UPS.
