UPS

[Thornless]

What UPS's are recommended for my system to give me 10, 20, or 30 minutes of  running time in the event of a power failure? My screen is a Samsung 18-inch TV. What kVA capacities do I need for the above?

I also have backups scheduled automatically every hour.

@Thornless, welcome to the forum.

I believe this is a question that is best answered by the manufacturer of the UPS that you choose.  They are the experts on their products.  You give them the information that you provided to us and they will tell you what you need.  APC seems to make very good products.

Thanks old_geekster for replying so soon.

I guess I didn't express myself clearly: I want to purchase a UPS, but I don't know  what the power requirement of my system is in kVA to make a selection. How do I determine that?

I've been to a supplier and that's what they asked me to find out.

Unfortunately, that's NOT a simple question to answer, as the TOTAL power consumption is the combination of ALL the hardware that is being powered, not just the PC, so you would have to include a monitor, and any other electrical devices that need to be powered while the PC is running. 

In my case, I'm using a CyberPower 1500 PSU, and it has a display indicating the power being used.  With a desktop, three hard drives, three monitors, is shows 1/5th of the power capacity being used -- about 300 watts.

So, using that as an example, it cost $150 for that UPS.  1000 watt versions cost around $100, and 550 watt versions less than $50.

I bought this one because it has to be able to power two desktop PCs, including a Server with 6 large hard drives and two monitors.

For a single PC, a 1000 watt unit should be more than sufficient.

Good Luck

Thank you, WAWood. That's the answer I was looking for.
