Backup power

[bfd]

Hello everyone,

I am looking for a backup power device, and I have found a few but was wonder does the watts of the back up have to match the watts of my power supply. I have a 1200w power supply and was considering a 1000w back up. Does this make any difference

I have

Silent Pro Gold 1200W - Cooler Master - Leading Provider of Computer Case | Cooler | Power Supply

I am considering

Intelligent LCD Series - CP1000AVRLCD | CyberPower Systems, Inc.

Thanks in advance

It's not a matter of how high your PSU is rated, but a matter of the total power draw your system consumes. There should be a volt-ampere rating on the UPS. Your total power draw should not exceed 60% of the volt-ampere. So you would take the total power draw and divide by .6 to get the needed volt-ampere of the needed UPS.

For example, if your system draws 500 Watts, you should divide 500 by .6 to get 833 needed Volt-ampere of the UPS. You can also purchase hardware that you plug the computer into to get the total power draw of the system as well.

The UPS that you posted is actually 1000Volt Ampere and 600Watt
