Backup Power Supply, which one should I get?

[ksculland]

I have two computer systems with 600 watt power supplies.

Typical power from the wall max so far has been at most 300 watts each.

The computers will always be beside each other.

I'm in Canada, Ottawa, so have up to $300 Canadian rupees to spend.

 

Should I be getting two separate backup UPS' or is it better to just get one larger unit?

Any other UPS units I should be looking at?

Any suggestions on which UPS is better?

 

• APC BE650G1 Back-UPS 650VA
• CyberPower CP600LCD 600VA 340W UP

 

• APC BR1500G Back-UPS Pro 1500 VA
• CyberPower Intelligent LCD Series CP1500AVRLCD 1500VA

 

Thanks All

Ideally it would be best to have separate UPS per PC as you can also setup an safe shutdown feature with software if there is an extended power outage and the battery starts to run down. Depending on the components of each UPS should be large enough to keep the system on at full load, as for a unit itself both APC and Cyberpower both make good units.

I went with the CyberPower CP1000PFCLCD UPS 1000 VA / 600 W PFC compatible Pure Sine Wave. Got it at a very good sale price.  I had read about many people having issues with the  APC version at the similar price point with newer computer power supplies that have Power Factor Correction (PFC).
