  1. i got a 850 antec power supply i was wondering do you need an 800 watt UPS for it to work correctly.

    my system spec.s are

    E6750 2.66 @ 3.2

    x2 1gig OCZ HPC PC 6400 memory

    8800GT superclocked 650 @ 720mhz (soon to have 2 in SLI)

    Nividia 680i mobo

    WD raptor 150g 10,000 rpm

    WD caviar 400g

    Not really.. Your PSU is probaly not running at 100%. But then again, you want that UPS to power your monitor too, don't you? And you may want the thing last more than a couple of minutes.

    The best thing to do would be to measure the power use of the system you want toput behind the UPS. A wattmeter is cheap. Then compare your wattage with the runtime chart for the UPS to see how long the thing would last in case of a power outage. (5 minutes is not enough to finish your stuff in the toilet, run to the computer in a dark house, save all your work and do a clean shutdown)

    Your system will draw less than 200w idle and less than 300w at full load

    A APC Smart-UPS 1500 should power that system and a 20" LCD monitor when it's idle for more than 30 minutes... (with fresh batteries of course)

    Least that's the runtime I get out of that UPS...
