Suggest me an UPS for my pc

post #1 of 7
Thread Starter 
I want to buy an UPS which can make my pc run without power at least for an hour cause the electricity in my country is bad it goes off after every 3 hours for an hour & I am sick of it & generators are a no go since they make a lot of noise & need fuel to run so I've decided to buy an UPS but I need help with the following things how much watts should the UPS be? how much VA & KVA & square wave or sine wave or pure sine wave & can someone explain to me what VA , KVA & what those voltage waveforms are??? what kind of battery will I need for it?


Will it run my net device too? cause a pc without net is pretty much useless & how many batteries can I connect with the UPS?? & tell me if I want to run my pc for an hour will it depend on the UPS or on the batteries?? & what kind of battery will I need for it? I've heard from people that you should buy a battery which costs about the same as the UPS


I think my pc needs about 300-350watts power to run

I've the following specs

4th gen i5
16gb ddr3 Corsair vengeance gaming ram
Seagate 1tb 7200rpm HDD
Corsair 240gb LE SSD
Gigabyte GTX 750 ti 2gb oc windforce 2x
Creative 7.1 sound card
Gigabyte H81 mobo
500watts Seasonic 80+ bronze certified psu
Corsair carbide 200R case with three Corsair 120mm AF fans + one Xigamatech 140mm fan

I've Creative 5.1 SBS A550 surround sound speakers & I am using a 23inch LG IPS 234v LED monitor on the power adapter of my monitor it says the following 19.5v
Input: 100-240v
50/60hz 125-160va
output: 19.5v 3.3A

I don't mind disconnecting my speakers when the UPS kicks in but suggest me an UPS that can at least run my pc and my monitor for an hour at least without no restarts


Homeage , Mercury , Emerson , Apc , Cyberpower , Alfa Digital etc are the following brands UPS the computer stores near my house are selling , there are China/local UPS here too but I was told by a friend not to go with local UPS as local ones are mostly used for fans and lights because they are square wave not for precision stuff like electronics and computers for precision stuff like computers, you'll need sine wave or a pure sine wave he said you can run a pc with square wave but the power supply's capacitors will degrade and damage the other components of the PC & he told me you might need around 50 AH battery to run it for 1 to 1.5 hours or so

We use APC systems at my workplace and its the only brand we use. I dont know much about UPS' but they seem to work great for all of our needs. Everyone computer here is running off of one.

After doing some research APC & Cyberpower UPS are the best brands , pure sinewave waveform is the best for pcs but sinewave will do the job too but pure sinewave will be better cause my psu is ActivePFC which helps prevent power loss when the battery is switching over most UPS have internal batteries which will give you 15-20mins , to get an hour I'll need to use an external car battery with the UPS & I'll need the double watts of what my pc requires & va is voltage amps the capacity of UPS is mentioned in VA, not in Watts & KVA is another term for 'Watts'

To get a UPS for your system (assuming 350w is accurate) that will power your system for an hour is going to be very expensive. I'd guess you are looking at $800 to $1000 USD for a UPS of that size.

Yeah the UPS that have internal batteries that can do an hour or 2 hours are quite expensive & for 1000$ ( if I had them) I could just buy a Solar panel system instead , what people in my country do is they connect an external car battery with the UPS so instead of lasting for minutes it lasts for hours depending on the power of the external car battery I heard its a bit risky using a car battery with the UPS but proper ventilation should help & I am just getting one external battery ( 150AH ) for it so it shouldn't be much of an issue cause some people over here are using Local/China UPS which are square wave with 3-4 external car batteries & even running tvs & computers off it without any restarts & they be using lots of fans , lights & fridge off it (I'll be only running my pc with one room fan during the day & one room light with pc & night since I am getting an Apc or Cyberpower (pure sinewave) with line-interactive so I should be good) I was told that 850va/500-600watts is enough for my system an UPS like that will cost like 100$ & a 150AH battery will cost 100$ so total 200$ , PS: We don't use $ currency we have our own currency

Guys after doing some more research not all UPS have internal batteries some do & some don't & remember that UPS rated in Volt amps rather than Watt so its not about matching your PSU wattage an UPS with 800-850va is enough for my pc , pure sine wave would be the best for my rig & that if I run my pc with a modified/simulated sine wave there's a chance that my pc would just restart cause my PSU is ActivePFC how ever I saw a comment in a different forum of a person saying if you run the UPS in narrow mode the restarts can be avoided now the problem is the UPS which internal batteries can do an hour or 2 hours are very expensive & the only cheap alternative solution is to use an external car battery with the UPS how ever the shop keeper told me you cannot use an external battery with the UPS that have internal batteries he said you'd need to buy an UPS that don't have any internal battery though the UPS of Cyberpower & Apc ( the ones without internal battery) they have are all modified/simulated sine wave they said you won't find an UPS of Cyberpower & Apc that are ( Pure sine wave) in which you can connect an external battery in our city you'll need to order one online

So can yall suggest me an UPS like that ? one without internal battery in which you can connect an external battery & is pure sine wave

I came to know its possible to get more time out of a small UPS by replacing its battery with a larger one but that depends upon the physical size of the UPS and its capacity to hold larger batteries & the second & the best option would be to buy an UPS that that has an external battery connector this is a safer, easier, and often more aesthetically pleasing option. The inbuilt charger in the UPS wont be able to charge a bigger battery anyway. Unless the UPS (Like some high end APC models) supports it, its NOT recommended. Buying a large battery with a separate charger for it which can charge large batteries and keep the charger with large battery always on this is the only way to run large battery with small ups.
