How does one choose these things?
My config ticket # = 656486 and I have this bookmarked: http://amzn.to/zypGrJ Will it be sufficient to handle my system? |

That UPS is rated at a maximum of 865W, your power supply is a 1050W unit. It may work but, you may run into stability issues with the computer.

So... the rule is to get something equal or greater than the max wattage of the computer (at least)?
It will have an external drive for backups, and the monitor will be on battery too. Have to take those into consideration? My printer is wireless and in a different room with a different circuit, and not on a battery. It's only turned on when necessary. No problem there. Edited by taw2015 - 21 Feb 2012 at 3:44pm |

All the devices maximum loads running off the UPS would have to be considered. Add the computers 1050watts, the external drives and monitors rated wattage to play it safe. Better too big than not big enough.

I honestly don't recommend a battery backup, unless you can find a high-quality unit and something that can be dedicated to the computer only.

If you really want a battery backup, you'll need something like this which costs $500, and will provide about 8 minutes of power for your computer and monitor. http://www.newegg.com/Product/Product.aspx?Item=N82E16842102068

I live in the Midwest, where t-storms are frequent, and although I tend to turn off a system before they get too close, there are always those unforeseen reasons that power goes off (like trees in high wind). Been living off laptops so long I don't know what happens anymore without a battery kicking in. If you're in the middle of a disk operation, all is lost, but is there anything else to worry about?

A surge from the power coming back could be an issue. You could use a quality surge protector to prevent that. |

Surge suppressor I have -- this is similar to one I use with my HDTV setup.
Are back-UPS almost always fairly expensive? |

The problem is.. well, yes, they tend to be expensive for a higher wattage. However, I will say, your machine will never pull 1050w, ever. That the maximum rated capacity of the your PSU, and in no way reflects what the actually running consumption of your rig will be. Case in point, I have a rig that would be more power hungry than yours and its currently pulling 315w (web browsing, etc.) and that includes my 24" monitor.

How do you know how much it's currently pulling?

Well, I have a UPS, but you could also use a Load/Wattage meter.

I found something that not only has a higher wattage spec, but is also a bit lower-cost than what Alex recommended. It also allows for piggybacking extra batteries for extended runtime.

His numbers (ie 315 watts) are typical of all computers. One once noted his biggest machine was consuming a large 410 watts. Most only consume between 200 and 350 watts. Grossly oversized (more than double) supplies are recommended to computer assemblers who don't have basic electrical knowledge. But the computer still draws that smaller power.
Is your computer as hot as four slice toaster? Of course not. You don't need a 1000 watt UPS. However a UPS is made a cheaply as possible.

I have an APC battery back up, I can't remember the model as I'm not at home right now... it's a tower model, I probably paid $150 about 8 years ago.
I use it to keep my cable modem and router up during those quick blackouts. I also run the PC and monitor off it. It's still on it's original battery and still provides the necessary time to gracefully shut down the PC. It also evens out power during quick brown outs. APC has always made reliable back up battery units and I have no qualms buying another APC product. Just my 2 cents.... |

I have a DSL modem and WiFi router and why didn't I think of that? There's nothing like squinting at a 3G-equipped iPhone when the power goes out when having to slog through a few dozen emails (let alone responding to them). Thanks for the "tip". |
