do i need to buy a UPS for my gaming PC ?

[Nancy the Girl]

can the UPS protect the PC  from a sudden electrical spikes ?

for example the voltage in my house will suddenly drop from 122 V to 99 V then up again to 115

I don't know why

but can that damage my PC or my monitor ?

 

EDIT :

on my old PC it was connected to a UPS but that UPS is very OLD 

and I don't want to connect it to my new gaming PC 

so I'm asking if I need to buy a new UPS for my new gaming pc or its not needed .

Most UPS have a surge protector as well as a battery backup, so you should be good. APC makes good ones, and you can even hook it up to your PC with a USB (I think? It comes with the cable) and monitor the charge levels and stuff, if you're into that.

A UPS does protect against voltage spikes, but that's not the primary purpose. It protects against the computer cutting off when the power goes out which is mostly a protective measure for data since cutting power doesn't do much to hardware. If all you're worried about isprotecting against electric spikes, just get a surge protector and save your money.

A surge is usually 110%+ higher than the nominal power. While difference in the order of +-30% are common and normal, they won't damage anything. A 440V can go down to 360 and up to 520 in industrial setups costantly.

 

No, it is not NEEDED to protect the PC with an UPS, but if it your PC costs thousands it's a good thing to do. If you are considering it only because of these "voltage differences", don't buy it. It's useless.

You can use one for surge protection, but they aren't designed specifically for that purpose. What is wrong with the old UPS? Is it not large enough for your system?

I agree, I never replace the UPS unless I need a bigger one. Almost all UPSs will let you replace the batteries in them, batteries usually last around 3-4ish years and then need to be replaced. Most batteries are around $20-30 So it isn't to bad.

I use a CyberPower UPS that outputs the current in a sinewave shape. It seemed to make my old intel rig run a little smoother (or placebo effect?) but my current Ryzen rig hasn't been plugged into anything else but I'm satisfied with my UPS. But I also invested over 2k in my Rig and all connected accessories and didn't want another power outage (had more where I live this past year than any year in my memory) to possibly damage anything. It's not usually necessary, though.
