hellow everyone,

I am having trouble with my UPS backup. my UPS is not giving me back up for more than 8 - 10 minutes.

I use a 2 battery UPS "maercury" brand. I added 2 new battary few days ago. they are Both Diamac Brand 7.5 ampears. My earlier battery was not giving me support more than 5 minutes. Those were 6 months old battery and at that time my UPS brand was APC. because of my low power back up i changed both the APC Smart Ups and the Battery. My current 'Marcury" UPS is second hand and in good condition as far as i know (tested on other computers) and it has Two transformer inside it. I added new battery there. But Still I donot get power Backup more than 10 minutes. As far as i know, this UPS was supposed to give at least 40 Minutes backup easily.

My Pc configuration is as follows. ( I recently added the new Thermaltake Power supply )

Mother board: Gigabyte - H81M-S2PV
Processor: Intel(R) Core(TM) i5-4570 CPU @ 3.20GHz
RAM: Twinmos 8GB DDR 3
HDD 1 : 320 GB Hitachi
HDD 2 : 3 TB Toshiba
GPU: 9600 GT XFX
PSU: Thermaltake 630Watt Model : SPS-630M (SMART SE 630W W/Active PFC)
My monitor is LG 19.5" model flatron W2043C

I also Use a TP-Link Wifi double antena Router by UPS.


Can You please suggest me the solution of my problem..
Will i have to purchase a new ONLINE UPS to Get backup like 1 hour. or there is other solution.
As far as i know with this configuration and UPS i was supposed to get at least 40 Minutes backup easily.

Thanks in advance for your help and suggestions.

Usually a UPS is meant to allow you to save and close everything, not allow you to continue like normal, so 5-10 minutes is pretty standard.

Not sure if you spelled it wrong but if it is a "Mercury" brand, they make very sub par products. You are better off with APC but even still 40 minutes takes a good quality brand like APC and one of their better home APCs to get to 40 minutes.

itismeti,

i think your expectations are a bit unrealistic unless you want to spend some serious cash.

i use an 1300va/780w APC battery backup myself which was close to $200 when i bought it. while my system specs are certainly higher than yours, at idle they will be not too far apart. i only get about 10 minutes maximum at idle on battery power. if under heavy load i'd be lucky to get 3-4. if your system draws less than mine (330w) you may get a bit more time but this is a good estimate.

to get 1 hour of usage at around perhaps 300-350w usage (figuring idle pc + monitor draw as estimate) you are likely looking at something like a 1920va/1920w model to get that sort of usage time. its a pro level model since home models cap at 1500va so costs $890.

likewise the most expensive brick style home option give 4-7min at $109, the tower style gives 14-21min at $240 while the smartups professional models start at $330 at around 14min runtime.

prices are from apc's msrp listings on their website but may vary from country to country so are provided as estimates only.

in general home battery backups are not meant for long term use and are only for emergency power to shut down the pc or to perhaps run something like a laptop for an hour or two or charge a few small devices during power outages.

to get any sort of real continuous usage during a power outtage you would need either a larger more expensive unit or a bank of car batteries with an inverter to provide power (similar to what people do when they live off the power grid).

in any case.... the cost of battery backup for such a long time as an hour or more is going to cost more than your computer is worth.
