Did you plug your PC into the ports that actually provide backup power on your UPS or just the surge protection ports?

Common household electrical outlet circuit breaker is 15amps.
Count everything plugged in at your house and add up the watts on that circuit.
You can't use a UPS because you are already at the max amps or over for the circuit breaker.

Nobody is talking about how these new PC's eating so much power are exceeding breaker amps on the household electrical circuit.

If you are in Europe and on 220volts then you are ok. They have higher amp breakers than American households.

eu 230v outlets are generally 10-15a = 2300-3450w
us 120v can be 15-20a = 1800-2400w


sine is only needed for the old wallwarts with heavy 60hz transformers

switching power supplies rectify and chop up the 110-220v to a much higher frequency at 220+400v and run it through a smaller more efficient transformer

most pc power supplies can run on 90-250vac and only pull the current required
higher voltage needs less current for the same wattage


and the psu labeled wattage does not make much difference
it will only draw and output what the load requires
cpu+gpu tdp + ~50-80w for the rest

I'm in Europe and the power grid is not so reliable, especially during summer and thunderstorms.

My current PSU has 2 outlet ports and no surge protection ones so I don't think this is an issue.

If I buy a new UPS which is Line Interactive but instead of 600W is 900W,will I be ok?

I'm not talking about power going out for 1hr but the sudden power offs that last milliseconds.

Could it just be the battery needs replacing?

Unfortunately it's built in so there is no way to replace it.But I don't think it's the battery since the UPS is less than a year old.
Anyways I already ordered a new one and fingers crossed 🤞

You should have been using 1500VA all along when using PC that can output 600+ watts from the wall

The thing is I'm new to the whole UPS area and can't tell what the VA number indicates.To be honest,I thought VA was Volt X Amps = Watts but apparently this is not the case.
If anyone cares to explain I would be grateful.

It's not really about the size of the PSU. It's how much power your system draws at any given moment. I have a 1000 watt PSU, but even under load my system doesn't ever go above 700 watts.

I got one of these[www.amazon.com] from APC. True sine wave output, 1500va, up to 900 watts capacity. With idling or light tasks I get about 40 minutes in an outage. When gaming, I would get 10-15 minutes, but that's more than enough time to save what I'm doing and close it down.

My only complaint about it is that APC stopped supporting their "Powerchute" software for managing the UPS, and the thing they replaced it with requires an account and a login. Thankfully, the version of Powerchute they do have still works fine, and will probably continue to do so in the foreseeable future.

1500va, 900w cyberpower, or apc (watch for apc, last one i ordered came with a bad battery, the first one i had was great, but died to a lighting strike (saved everything, but itself, it also uses powershute personal).

now, i run 2 cyber power 1500va, 900w (cp1500avrlcd3) ups's, one running 2 tv's/router/etc.. the other running the pc.

powerpanel personal (from cyberpower), is the software required for it, to be installed on the pc.

they shut down your pc, according to the settings you set them to shut off at (or i suppose shut stuff off by default, without using said above software), through w/e software you install to give you its config, info, etc...

you can also set them to not shut off your pc and keep running until they lose all power and thus allowing you to shut down your pc manually, if you choose.

as for your pc's watt usage, its likely not using anywhere close to the amount supplied, or at the very least shouldnt be.

as for anything higher than 900w, the price jumps much higher.

you dont need sinewave, you can use one without and have zero issues, i ran my corsair hx1000i psu, on a non-sinewave ups for 8 or so years, replaced said ups (due to mentioned above) with same spec ups, but through another brand.

that is not at all whats going on and "american households" circuit amperage, runs all these pc's perfectly fine, without issue.

if you are having issues like that, you might check how many things you are running on said single breaker, then spread that or dont run all the stuff at the same time.

whole house wattage, has zero to do with a single circuit, as all houses are running certain amounts of outlets, off of various circuits, divided up throughout the houses.

my breaker box has somewhere around 20-30 circuit breakers, varying in amperage, most 15a, with a few 20a, depending on the appliances, the room and how many appliances are in said rooms.

my pc, the 2 tv's, the router and a 400w stereo receiver, 2 900w ups's, plus odds and ends, all running off their own circuit (i ran directly to my pc room), on a 15amp breaker, i can run all that at the same time, with zero issues, that you claimed, even while playing games on the pc (which obviously pulls more power for the pc, or less when just watching vids, etc..).

my room also has much more going on, ceiling fan with lights, random fans around the room, other lamps and various other odds and ends, including a windows ac (6k btu's) running 24/7 during summer (or a 1700w space heater during winter) and despite that, zero effect... why because circuits only run certain amounts of outlets, before a new one is added and a majority of stuff wont pop a breaker unless it runs over its max wattage (dont remember off hand 15 amp max wattage).

have a nice day peeps
