Thanks

462951 2006-06-14 05:04:00 Depends on what the power factor of your pc/monitor is, usually for just one or 2 pc's you would get about a 700 VA UPS, that will give you around 10 - 15 mins backup power when the UPS is running 100%. A 700 VA UPS is usually around 450W which is more than adequate for your average pc.

Check out www.ceds.co.nz and get them to see what they can do for you...

Try an APC Smart ups 700,
or a Liebert Powersure 700.

462953 2006-06-14 06:13:00 check your pc specs. 700va will not run a lot of things. don't any addons ie printers, speakers, usb hubs etc that need power.

the other main thing to consider is what TYPE of UPS. the basic type is nothing more than battery backup it dosn't regulate the power so you can still suffer low voltage problems. interactive/voltage correction/regulated (different brands use different names for it) basicly regulate the power as well as a battery backup. ie if input is 220v you will still have 240v output where as a basic UPS will give you 220v output.

unfortunatly the interactive type are double the price but they are a goodsend for rural users. just watch you don't get suckered by the "power filter" which some people claim does the same job as the interatice type. the all have power filtes, its not a feature, its just advertising bull.
