Your system shouldn't pull more than 400-450W (PSU inefficiency accounted for) so you will need maybe a 900VA UPS

Depends on how long you want your machine to run for and what you expect your machine is doing during that time.

A UPS shows how long it will run, depending on how much watts your machine is using.

 

So do you want to play games/edit videos/etc. or do you just want to be able to turn off your PC within a normal amount of time?

Simply put, during high load scenarios (like gaming and such) your PC will use about 350W. During 'idle', your PC will use closer to 100W. That is just an estimation.

 

So looking at this 900VA mode from APC, this is how long your system will run for:

So during a high load scenario, you will have about 10 minutes of battery time, while on low load scenario you will be getting closer to an hour.

 

Just think about how long you want to be able to run your system, what kind of load, how many plugs you need (keep in mind usually a UPS has battery+over current protection ports & only overcurrent protection ports).


I apologize for the way I am. If my post seemed rude, that was not my intention. Just my ineptness in forming a nice coherent message.

"those times will never come back :("

"I wish I could find a way to end the pain, other than the way I keep thinking of"

most UPS'es wont even run 12 hours without load on it, let alone run a pc.

 

if you want actually extended runtime, you'll have to look into seperate inverters and battery racks, but expect to shell out some serious dough for that.

I don't think thats the point of UPS. You should look for aggregate if you want to have sustained and outsite the network power delivery. UPS is for giving time to shutdown system with control. Or to keep it running during short cuts in power delivery.

I just showed you a graph for a 900VA UPS, which - as I mentioned in my previous post - would give you about 10 minutes of gaming:

[...]

So during a high load scenario, you will have about 10 minutes of battery time

So a UPS with 10% more VA, would not suddenly go from 10 minutes to 12 hours. It would be more like 11 minutes.

 

If you want 12 hours of gaming time, you would probably need to look in large rack UPS models (which would cost within the 10's of thousands of dollars), or look into a generator (running on petrol or something).

This video shows some information on using a generator:

 

P.S. a UPS is more meant for a limited amount of time of usage, so you can shut your PC off 'gracefully', instead of abruptly.

if you pair an inverter/charger with some bigger batteries (yacht / RV batteries), especially when going towards 48 volt (or higher) systems, you get quite decent runtime.

Huge misinformation. The VA rating has nothing to do with how long it will run on battery. VA is the max power the UPS can output. Battery capacity says how long it can run for.

Thanks for the correction, I indeed worded that in the wrong way.

What I just meant to show the OP was that 12 hours of gaming time on a 1000VA UPS (assuming it was the same range of UPS) was quite unrealistic.

 

Should not have mentioned VA as a measure of how long it would run. Thanks again for the correction!
