UPS buying suggestion

[yudi v]

I am planning on buying an UPS to protect my HP microserver
n40l<http://n40l.wikia.com/wiki/HP_MicroServer_N40L_Wiki>,
it will be running FreeBSD 9.2 RELEASE.

I am looking at
APC Power-Saving Back-UPS ES 8 Outlet 700VA 230V AS
3112<http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=BE700G%2DAZ&total_watts=400>

is that supported by apcupsd? (already tried apcupsd mailing list, there
was no response, hence asking here)
 If not, please recommend one that is supported.

The HP server has a 150W PSU and the UPS is rated at 400Watts, and it comes
with USB monitoring support.

Also, how to measure exact power consumption by a device?
