I would like to buy a UPS device for a server that I run at home, I need some advice as to which one I should buy. Basically I will tell you my current setup and why it needs to be changed. I've got a UPS already but the batteries only last for about 5 minutes and then it just turns off (I haven't got a serial cable or shutdown software for it). The one I have is made by Socomec Sicon but it seems to be an unusual model and I cant find any information about it anywhere on the 'net so I don't know what the power rating for it is. I was going to use my old UPS to run my broadband router and a couple of network switches so that will keep the internet going as well then. The server it has to protect is as follows: 300w ATX power supply 2 hard drives 512mb ram AMD Athlon 700Mhz cpu I think thats all the important things when it comes to power consumption etc. If you need to know anything else just ask. I've been looking around on a few websites but I don't really know how powerful it needs to be to run my server during a power outage (they seem to be happening about once a day this week, so something needs to be done). I noticed on the ones i've been looking at, the power rating is in VA, but I don't know how many watts that is or how to convert it to watts etc. It would also be useful if the UPS would run an LCD monitor for a few minutes as well if possible but that isn't too important, as long as the UPS comes with automatic shutdown software. Please can someone recommend a reliable UPS which hopefully will run for 15-20 minutes with the setup I have. Or tell me a suitable VA rating which would run it because I have no idea how to work it out, and maybe have a bit extra power incase I add anything else to the system. I don't really want to spend more than £100 if I can help it. Thanks in advance for any help you can give me.
