Looking for a UPS line interactive

[dullbird]

Hi Guys

Need some advice

I was just about to buy an Eaton E-series 2000va, 1200W for my computer that I have had rebuilt by dave.

The reason for this is mainly because my last computer looked like it had been hit by lightning (even though it was on a surge protector
) or been subjected to a long brown out..everything was caput inside.

However in looking at the details it only gives the run times up to 600W which is approx 5 mins.
I have just looked at my computer and it has a 700W power supply:(

so can I assume this Eaton would run this just for less than 5mins..or should I not assume and look for something else more suitable.

I really dont understand these systems that well other than I know I need one with AVR to smooth out power fluctuations to help prevent having to buy a computer every 3 yrs.

Can someone tell me whether this Eaton will suit or whether they can point me in a direction to another Make model that will thats not going to cost me the earth...

the link to this eaton is here and from what I can see is the higest power one in the E series

Yes you will get slightly less than five minutes based on their figures if your computer is drawing the full 700 watts. Although your power supply is good for 700 W I doubt that it is pulling max power all the time. And that 700 W is most likely what it can deliver and not what it will draw, the switch mode power supplies are pretty efficient so we will not confuse things any further.

All that time figure for how long it will hold up the load is good for is to let you know how long you have to make an orderly close down of the applications so that you don't lose any data.

they come with software I believe s they automatically shut the computer down for you which would be good if I was away from the computer when it happened.

So are others of the opinion I'm safe to buy this unit? I would like to hear from people before I fork out 280bux.

[dullbird]

Seriously there must be others out there that have or work with these units do others agree with slug burner?

It will vary dependent upon what you want to do.
Do you want to have your monitor plugged in too? Another 75w there (typical flat screen). If there is a black out and you want to shut the machine down gracefully that's important.

You will also be surprised how little power the PC draws especially if not working very hard. Maybe only 100-200w. If anyone has "tong testers" they could check. Typically grunty video cards chew up the watts.

[dullbird]

no only the computer will be plugged in...so simply looking to smooth out power fluctuations and have a safe guard for shutting down in the black out thats all im prett much after really.

The UPS and all other things will be plugged in to a surge protector

[shining]

Will you be able to shut down without the monitor plugged in?

[incisor]

the software does it...

the unit should be fine imho

[shining]

Correct... looks like the UPS has got a USB port for winpower. I have no experience with this. Our gear is ethernet enabled.

[dullbird]

Ok well thank you all I will go ahead and purchase....:)

For that sort of money I doubt you will get much better.

I do not have the experience with the software that the UPS comes with to be able to comment on its ability to perform an orderly close down of applications.

A few years ago we had to provide UPS back up for some Unix systems which needed over ten minutes to close down, we used APC UPS and they had the ability to use a draw of external batteries to increase the amount of time they would hold the load up after loss of external power. As far as brown outs the UPS would select different transformer tap setting so that it compensated for under and over voltage conditions. Can't remember what brown out voltage it would hold on to before it isolated the line. Neat piece of gear and they have improved the ability to monitor remotely now that everything is plugged into a network.

Purchase done....I didn't think it was a bad price over 300 with most companies.
