[NBA]Suggest me an UPS for my pc

[3hunna]

I want to buy an UPS which can make my pc run without power at least for an hour cause 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?


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

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 Islamabad 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

Common guys reply!

I think the APC 1000va or higher ones are pure sinewave and they are modified to be able to run external batteries. These are available in khi market

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.
