Look at "Output power capacity". It is only 300 Watts. You need to connect your monitor to it too so that if you lose power, you can see what is going on. That means if you have a CRT, it leaves 200 Watts for your computer. If that is enough for your computer, it is fine.
If your PC needs more power, you may need a UPS that can provide more power.
i really dont know how much output power will my computer be...the parts are on the way here....so looking at the specs, what do you think???
Your CRT needs about 100W. That leaves only 200W for your PC. You have a 450W power supply!
Often people confuse the maximum power capability of a UPS with its energy capacity. The two are not related at all.
The maximum power a UPS can safely provide has to do with its output resistance and its efficiency. Only the manufacturer can improve the maximum power of a UPS. If they do that, but, put a very small battery in the UPS, the UPS will run out of juice very fast even though it can deliver high instantaneous power while the battery lasts.
The time it takes for the UPS battery to run out, after you lose the line power, has to do with the energy capacity of the battery. You can plug in 20 batteries, in parallel, and your UPS will be up and running for 2 hours. But, that does not mean that it can provide more power.
Power is the energy delivered in unit time. How fast a device can deliver energy is its power capability.
How long it can deliver energy is its capacity.
You need to improve different sections of the device in order to improve each of the two.
I would get at least a 400W UPS for that system.
