Best ups for 850w psu

[sparrowman]

Hello I m Jiten. I m from India. I want a strong ups for my 850 watt psu. In our area there are low voltages. Right now i am using 600va ups and this ups is fluctating. my specs are:
mobo- gigabyte g41mt-s2p
graphic card- msi gtx 970
ram- 8gb
hdd- 1tb
cpu- core 2 quad Q8400

See http://www.newegg.com/UPS/SubCategory/ID-72

When I say 501-1000W it shows - http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&N=100007932%20600013484

If you put in price, battery run time and/or VA then you can find the UPS that will serve you well. Then have a look on Indian websites -

India
Flipkart Sells PC components in addition to lots of other goods
The IT Depot
Lynx Chandigarh
Swami PC
Techshop
Shopmania
MD Computers
Prime ABGB Tech Heaven


to find if they have what you want for a resonable price.

APC BR1000 i have already bought it and i returned it also. Because it fluctuates when the my voltages are low.

Then choose another.

 

[GhislainG]

Then choose another.

The utility voltage drops so low that the UPS has to switch to battery, but it still provides output voltage within specs. I presume the OP is looking for a UPS that won't switch to battery even when input voltage is lower than the minimum range.

 

[i7Baby]

He hasn't said.

 

[sparrowman]

Then choose another.

which one? should i bring apc BR1500 ?

 

[i7Baby]

I don't know what you want or what your budget is. You have to choose.

Or can you tell me how many VA and what battery run time you're after? And what budget you have?

Who know? Your budget might be too low to buy what you want.

yes you are right. Your thought is right. So what i will do now.should i bring apc BR1500?

my budget is Rs 12000. I don't want high backup. I want a ups which can run in low voltage. Cyber power ups is a good ups? But this product is not available in our country or online shops.

UPS are made so that they run on the battery if the voltage goes low. If you don't want a 'high backup' then your UPS will keep shutting down.

In my apc 1000 va ups, the led screen shows 236 volts when enough voltages are coming but in low voltages the led shows below 200 volts and the ups fan also starts. The fan sound irritates.

 

[i7Baby]

If the fan is too irritating then try without a UPS at all.

how? impossible if line will go. My pc will be direct off.

So - UPS with Fan or No UPS? What do you prefer?

If you want a UPS do not complain about the fan. The UPS is doing what it's supposed to do. If your household voltage drops low, then the UPS should cut in. If this happens a lot then you need a very 'high backup' - a good battery.

like inverter? right?

you told a very 'high backup' - a good battery. Like inverter???

Buy a good CVT that provides output voltage between 220 and 230 volts and connect the UPS to it; that should resolve your issue as long as the CVT doesn't become noisy when it has to work harder to maintain voltage within specs.

Hello,

Given the voltage problems on your grid, no UPS will allow you to properly use your PC (the batteries from the UPS will never properly charge). Use a voltage regulator (AVR) BEFORE the UPS, something like this: http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=LE1200I&ISOCountryCode=de.

Your original 600VA UPS is also a little bit too small. Your system will need 350W DC power, so if your 850-watt PSU is of a decent quality (at least 80% efficiency, active PFC), you will draw from the grid 500VA. Adding the monitor, you are reaching the UPS power rating. If the PSU is old and inefficient (under 60% efficiency, passive PFC), the system only can easily draw 700VA from the wall.

That APC didn't work as it should or you were just annoyed by the fan noise?

I have a electronic voltage regulator and this voltage regulator volts are 100 volts to 300 volts. Inverter will be cool for me?

I have a electronic voltage regulator. Should i fix a inverter?

 

[GhislainG]

What happens when you connect the UPS to the voltage regulator? If voltage is within specs, then the UPS shouln't switch to battery.

yes my electric voltage regulator gives extra voltage to my apc BR1000 but this voltage regulator sound and also my ups sounds. I mean it is switching the battery. Tak. Tak !!!

 

[GhislainG]

Even the APC unit suggested by Cristi72 will make noise when it switches on to regulate the voltage. Best would be to install a good voltage regulator where utility power comes in to your place; if it's in a closed room then you don't hear it.

how about installing a inverter? should i test a inverter to my 600 va ups?
