I've had good luck with Refurbished UPS |
18 |
<http://www.refurbups.com>. They rebuild |
19 |
APC units, have decent prices with full |
20 |
warranty. |
21 |
|
22 |
Short of a full outage, a line conditioner |
23 |
works equall well (APC makes several good |
24 |
dones, 1250VA being more than enough for |
25 |
most PC's). |

After that you can get a "Smart UPS", which |
28 |
is basically a line conditioner and a battery |
29 |
in one box. This solves your flicker problems. |
30 |
A Smart-UPS 750 will probably handle anything |
31 |
you need for a desktop and L[CE]D screen, for |
32 |
two of them you can get a 1.5KVA that will give |
33 |
you plenty of time for shutdown even with two |
34 |
machines. |
35 |
|
36 |
For a home unit, your best bet is to size the |
37 |
thing for a reasonable shutdown period rather |
38 |
than try to keep everything running through |
39 |
a potential blackout. Reboots don't take that |
40 |
long and the cost+overhead of running an oversize |
41 |
unit adds up. You have a different calculation |
42 |
for servers or racks, where uptime is more of |
43 |
an issue. The bigger ones also weigh a helluva |
44 |
lot more, which doesn't sound like anything |
45 |
until you break a desk or warp some shelves |
46 |
unnecessarly :-) |
