pc restarts following power cuts

Specs: WIN XP SP2
My desktop pc often restarts following power cuts despite a good quality new ups(APC 600W) is attached to it. i've already contacted my hardware vendor. he 1st replaced the old ups with the new one...it brought no hope for me. then he changed the psu. that too did not do anything for me. the ac mains voltage is alright too with a good grounding. i want my pc to stay unaffected after power cuts as normal cases. but its still the moon under the sky for me! can anyone help?
thanks.

Have you installed the UPS software and a cable from the UPS to the computer? There might be some setting in it's software that may be doing this.


I'd suspect that the ups isn't providing enough or correct or stable enough voltage and frequency. Some have the pseudo-sine waves that some power supplies don't like.

Might try a true sine wave ups.

The simple test would be to remove plug on UPS side to test.

Usual usp's have a self test and a front panel test button to set a load on battery. It may fail on that test too.

thanks for your reply jefro. i dont have any software for the ups. and the document says its a square wave line interactive
ups. i've tried with my friend's ups too that runs well on his pc. but no hope for me with this one. please tell me a wide range of possible solutions.

The UPS capacity is too low. You are expecting a longer run
time? Home UPS's just give you enough power to safely shut
down. If you want longer run time get a generator.

can u guys suggest a psu that is a capable of handling square wave input? i believe a true sine wave ups is too expensive! and right now my pocket will not permit it.
