UPS for PC and TV

himen256 · 25 Oct 2017 at 22:21

Hi, for last couple of weeks I have drops in power or something. Every now and then my tv go black for 2 or 3 seconds no more and then is back to normal. I'm scared that if this continue it will damage my TV. What I want to do is buy a small UPS to supple nice clean power to my main TV and my PC with one 32" TV and 24" monitor. I have no idea what to look for or how much power would I need. I dont need to run it for long time but 5 minutes would be nice so I can power everything down safely. Power wise:

Main TV = 220 watts
32" TV = 200 watts
24" Monitor = 29 watts
My PC have 750 watts PSU and specks as in signature dont know how much it pulls from wall.

Any help would be nice and dont want to spend a fortune

Are all the lights in the house going dim?

My main TV is on the same breaker as light in my room, light in a bathroom and exhausting fan in bathroom. After a bit of testing today I did notice something odd. When you turn light on in the bathroom the fan kick in my TV is fine, when you turn light off fan stays for next 3 minutes or so as it should and my TV is still fine. Now when you turn on the light in bathroom while fan is running that's when my TV goes black for 2/3 seconds. I did check the breakers but that's only thing I can do. This is a rented house and my landlord is not the best person to deal with and prefer to keep him out of this.

Now back to UPS any one any advise? Do I need the same amount or more of watts in UPS? Or can I get something smaller(cheaper)?

Well, here's how "clean" power cheap UPSes give:
https://www.hardwareinsights.com/database-of-ups-output-waveforms/
Google for sine wave if you don't know what voltage wave form should look.

Unless you're using dark sunglasses/welder's mask you can at least half the figure for TVs.
Full brightness settings are about blinding.

That could hint to some kind interference or maybe problem with wiring.
Surely that fan shouldn't be high power one and neither should normal light cause high power draw.

I'm not looking to fix it, that would involved calling my land lord and that's a bad idea. I did notice that black outs are not happening every time but random. I did have a look at that website you posted and now I know less then before. Can you help me out in getting the right UPS for my needs. I'm not looking to run my set up off back up but only deliver clean power to it. I was thinking a UPS will do all those thing but I was wrong. Let me know what you think.

heaven forbid you ask him to fix a potentially dangerous wiring issue..

I have been in this house for last 8 years and my rent is 1.4k while a house next to me, identical own by the same person is 2.5k so yes I'm not calling my land lord for any reason.

Where on earth do you stay? Kensington?

My rent is the same as the day I move in. 2.5k is normal for 5 double bedrooms with big garden and driveway.

Most of the time all of my staff is not on, my pc is on 24/7. I only have my main TV on when other two are off as they are on the opposite sides of the room. I'm extremely grateful for all the feedback I got. Now can I get one that will fulfil my need for £100/£150?
