Hello, I'm considering a UPS Power supply and want an adequate amount to back up my 750 watt corsair supply. Do I need the equal wattage in the ups? If not then what needs to be considered when determining a ups for my needs. I don't really care much about battery life in the event of a power failure as much as I do WANT TO PROTECT MY PC FOR A GRACEFUL SHUT DOWN.
I'm asking because these UPS supplies are pretty expensive I want enough to protect and dont wanna waste money.
I just finished the Toms Hardware $1500.00, March 2010 build. Its my first build and it has gone great so far not a problem anywhere.
My advise to anyone not sure of themselves on the first build. Do what I did take a build receipe that fits your needs and pocketbook and go for it.
I figured rather than take the chance of hooking together components that might conflict go with a tested and well rated build.
If you want safety for your computer equipment when there is a power outage, you also need to power the monitor for a safe shutdown. The shutdown can be programmed to be automatic, but you certainly need some form of manual shutdown capability too.
Therefore, consider the computer, the monitor, and maybe a small low wattage lamp when you size a UPS.
In most cases, no one maxes out the PSU; therefore matching the PSU output may be overkill. However, you must provide for about 80% of your PSU capacity which is around 600 Watts. To this, add the monitor consumption (100 Watts?), and a lamp (23 Watts), for a total of 723 Watts UPS
