    It seems to me that 800VA != 800W,because there should be Power factor taken into account,which is generally 70-80%(0.7-0.8).So formaula to convert it into Watts would be something like

    V*A*(power factor)=800*0.8=640 W.Now if your PS3 requires upto 350 W.And its working when you applied more load.I would guess that UPS is considering your PS3 load as “NO-Load” condition.No-load thresold is generally defined by manufactureres.There could be two solutions
    1.As you already did,Increase the load
    2.adjust the UPS “load load” circuit sensitivity so that no-load thresold is decreased.Regarding this you should ask Microtek.

    (during backup) PS3 is on working gr8 , TV restarts and works fine there on. my only concern is that stupid restart in the TV which want to get ridd of … TV load = 200watts PS3 load = :unsure:

    load capacity of UPS in watts = :unsure:

    however the TV does not restart during backup when the PS3 is not running , so i assume it has something to do with the load on the UPS and tripping of the TV :scratchchin:

    My son has purchase a microtek UPS 800 at Vir Shavarkar block shakarpur, Delhi but it not working upto mark. As light goes the UPS did not go off automatically after 30 seconds and hapen other good quality UPS.

    I have registred a complaint on line with address and mobile no but more than two months has elpsed but no one turn up or any communication from this good company. So I think the UPS system is not upto quality only taking advantages of Inverters. Will any one in microtek is monitoring such complaints. I hope.
