Choosing a UPS

post #1 of 21
Thread Starter 
So I've read a couple of guides about choosing one and it's a bit complicated to me tbh.

What I know is that I multiply the wattage by 1.6 and I have the VA.

I have a 1000watt PSU what will be connected to the battery (not even half of it is used but I'm going to calculate all of it for future upgrades to my pc) my monitor is said to consume 46 watt which I want to be connected to the battery as well as my rooter which I have no idea how much watt it needs.

Let's say all in all I have 1100 watt so in theory I need a ups greater than 1760VA so I thought a 2000VA would be perfect.

What I want to know is firstly if I can also connect my speakers to the battery (logitech 5.1) or it will drain the battery very quickly.

Secondly I definitely need to connect my keyboard to the brown-out protection (I believed that's what it's called, protection without battery) because I've heard many g19 keyboards dying from thunderstorms.

Thirdly I wanted you to give me your opinions on what UPS I should buy and which technologies I should look for in a UPS (got absolutely no idea about that) also if I'll need more VA or less.

Holy hell! It is UPS night tonight.
First we need to know how much load you will be pulling from the wall. That is correct, wattage is 60% of the VA rating.

2000VA would be a good oversight if you are pulling 1100W, although in practice you won't run that much load whilst on the UPS. Although in saying that, if you have a 1000W power supply, this doesn't mean you will be pulling 1000W. Around 800VA should be sufficient for your system, UNLESS you know you WILL pull that much wattage constantly.

I'd recommend against connecting speakers to a UPS. It won't run for long and it not designed for that equipment.

Technology you should be looking for in a UPS is line-interactive/automatic voltage regulation. You will get brownout and voltage spike protection with this without draining the battery (within a range of about 90-140V. Anything lower and the battery will kick in, anything higher and the UPS will direct current to the ground).

You may also want a true sine wave UPS, if your power supply has active power factor correction (active PFC). Simulated sine wave UPSes can cause active PFC power supplies to drop the load when switching to DC mode.

Well tbh I don't know how much my system draws, but it's definitely around 300 watts, the thing is I bought that power supply because I intend to do future upgrades to my PC that's why I'm aiming for a ups that will accommodate those upgrades. I don't want to get in the hassle of needing to buy a UPS again just because my current one won't do the job once I upgrade my PC. Also as far as I know having more VA will prolong how long the battery will hold out so it's not such a bad thing I guess? But my main concern is to never have to upgrade my UPS again.

Also according to here my PSU has active PFC.

I won't connect my speakers to the battery based on your advice but can I connect them to the brown-out function?

EDIT: I'm pretty sure it draws 300 watt or less on load because my PSU has a functionality in which the fan won't start working unless there is more than 30% load or 30 degrees Celsius of heat and that fan has never even started on complete stress tests I've done tongue.gif

Picking up 2000VA certainly won't hurt smile.gif

Like having special plugs that do not offer battery power, but they offer protection

I haven't seen any UPS that can do this. You probably want just a standalone line conditioner for this task!

So what I could do is buy a UPS for PC + monitor + rooter + keyboard

and buy the voltage regulation thingy just for my speakers to protect them. My speakers output 155 watt total so I guess a 200watt voltage regulation would do it.

Just for paying less and not buying the voltage regulation at all could I even put the speakers on the UPS and when the power goes off just turn the speakers off so that they won't drain the battery? Or is it plainly wrong to put speakers on a UPS at all?

Nope that will be fine smile.gif
I just recommend against running them off battery from the UPS because its kind of pointless, especially consumer grade UPSes where they cannot support a load for much time.
