If you have two desktop PCs plus monitor and switches I would try to get |
40 |
1500VA or more. |
41 |
|
42 |
I have tried Tripp-Lite, Cyberpower, and APC. So far, the best luck I've |
43 |
had is with APC. |
44 |
|
45 |
I started out with APC initially (small unit, 350VA) and paid the |
46 |
premium price. The second and third time around (not replacing, needing |
47 |
new UPSs) I tried other brands. First the Tripp-Lite, it was OK but a |
48 |
year and a half later it just died with no warning. Got a replacement |
49 |
battery and still no go. So I bought a Cyberpower UPS. This one lasted |
50 |
almost two years, and when the power went out the first time it worked - |
51 |
but the second time it went out when the power came back the UPS fried |
52 |
and it unfortunately took out my PSU, motherboard, and hard drive. For |
53 |
some reason the monitor survived... and no, I did not have any |
54 |
high-amperage devices attached (printer is in a different room.) |
55 |
|
56 |
Anyway, after that experience, I stuck with APC. I currently have four |
57 |
of them, a little 350VA guy for my modem and switches, and 3 1200VA |
58 |
models. These are old now, bought in 2004, and other than having to |
59 |
change one battery in one of the units, they all still work. Nine years! |
60 |
|
61 |
I also recommend APC based on my own experience. Yes, they're more |
62 |
expensive (in some cases 50% more) than others, but longevity seems to |
63 |
be great. Plus you can use apcupsd for monitoring in linux. |
64 |
|
65 |
We also use APC at work. While a few have had their batteries changed, |
66 |
most of the units themselves are at least 10 years old. |
