This prob is UPS based.. certain UPS produced are based for minimal power specs of a computer and once the computer is under heavy load more power is consumed and thus the UPS cant supply what is required and then the restart as ya say occurs..
My UPS supplies power to 2 computers and yes if the computer load is higher at times it switches off.I had mine replaced with another similiar one though and that gave no problems.. the problem is UPS based and not computer based..
go for a good brand with a good power supply rate... make sure your UPS supports more than what ya require for safety.. constant sudden power off/resets does not make anythin easier on the mobo..

As i mentioned buddy.. to cut down costs dese manufacturers base it on the minimal power spec.. and when ya have a powerful colour card combined with more hardware attached the need for alternative power supply via the UPS grows, and once the limit is reached the UPS resets.. I have experienced the problem.. the only efficient solution would be to have a more powerful UPS in the sense a UPS which supplies more power that what would be required for a single PC..
Else, disconnect the addional hardware such as printers, scanners which might be attached to the UPS and try it out.. but i doubt whether it would work..

ya but inmy case once da whole ups got switched off and restarted.....zerocool said:that is not an option for the ups...if there is a high voltage ups must normalize it and send it to the pc, that's what ups do right..
hey anusha....what HishamZz says may be correct...if u wanna test it u can do dis......while da pc is on switch off da pow to da ups...den da pc runs on ups ryt?? den switch off ur monitor for abt1 min and den switch it on!!! da samethn will happen....i thnk dats bcoz of dat what HishamZz is sayin
Oh ok. Seems like I'm the only one having this problem in this whole community.
I have solved this problem however. Just wanted to know what you thought about it and help others if they have this problem too.
It wasn't the UPS!!! It was the power supply.
Every Power Supply Unit has a thing called hold back time (the terminology may slightly differ however). This shows how long the power supply can hold PC working, even after the power fails. Obviously this is int milliseconds. This is what an UPS exploits when switching to the battery. The Power Supply Unit's hold back time should be longer than the UPS' switching time.
The hold back time is determined by the capacitors inside the Power Supply Unit. When a bigger load current is drawn from the capacitors, they discharge quickly, and the hold back time will dip. That's why it might reset the PC when doing a stressful task, than when lying idle.
The generic power supplies we get in Sri Lanka for around Rs.1,500 or even less are not good. Their hold back time maybe be enough when no so much power is drawn from the power supply, but once a high power is drawn, the hold back time will go down tremendously.
I don't think the UPS we get for around Rs.4,000 are bad. But a faster switching UPS would have been able to cancel the incapabilities of the power supply unit, but by how much?
I had to buy a good power supply to get rid of this ghastly problem. This is a server power supply (well, that's what they call it), and I had to spend Rs.5250 on it. It's still not the best by all means, and enthusiasts will call this a very low end power supply unit. But at least, I got my problem solved by buying this power supply.

You should not turn on a CRT while running in battery mode!!!!
It's not a problem with the UPS. CRT monitors draw a huge amount power when they are starting. After that, it will come down to around 70-100W.
3 years now......but dis prob came 2 years bak wage.....and i din get it for a long time nowzerocool said:then it is problem in your ups..how long have you been using this ups.
still on da same ups

You know, your UPS may also contribute to this, because of the age. But it's more the power supply than the UPS which is the culprit.
ok so den y dawhole pc gets restarted??Anusha said:You should not turn on a CRT while running in battery mode!!!!
