UPS for FreeBSD

[Alejandro Imass]

Hi,

I'm looking to buy a UPS for a server I have at home that will work with
FreeBSD and can signal for server via USB to gracefully shutdown when power
goes out.

Do any of these work with FreeBSD via USB?

- CyberPower Standby CP425SLG UPS
- CyberPower Standby CP550SLG UPS
- Tripp Lite ECO Series 350VA UPS
- Tripp Lite ECO Series 550VA UPS

Or any other off-the-shelf inexpensive UPS that I can buy at Staples or
Best Buy that will work with FreeBSD via USB to shut down the server
gracefully.

TIA,
Alejandro Imass
