UPS online Fully Protect Against Input Lag from Electricity?

[Slender]

@Chief Blur Buster, do you have any data from which you can conclude that we have different problems? Why are people from different places on this planet talking about the same issues?
Where did you get the idea that this problem occurs in a negligible number of people?

I would have preferred a single device so that I can easily return it.

Unfortunately:

UPS = McDonalds Hamburgers
"inverter + lithium iron battery" = Luxury BBQ T-Bone Steaks

Fortunately, Amazon sells both items into a single shopping cart, so they can be returned together. However, it's a bit risky to get into these because it's a bit of an "electrician DIY".

So you have a choice of paying 3x as much for a single device, or much less for two devices that you wire together.

It is not a 100% guarantee, but it's the cheapest way to get about 2-3 hours of gaming off-grid with just a single car-battery-sized lithium battery. Those common cheap new "12.8V 100 amp hour" (1280 watts hour) LITHIUM iron-phosphate car batteries can power an RTX 5080 rig for 2-3 hours including the gaming monitor.

Have extra money? Good. That makes things easier. If you prefer a single solution, get some Jackery Power Station or clone thereof. Anker sells them too. Big battery on wheels that you can plug in. The 2400 watt-hours ones can even power an RTX 5090 rig for a few hours. The power from these modern power stations ("giant lithium battery on wheels"), especially of good brands like Anker, is generally much, much cleaner than the power from the grid if you're living in an unlucky country.

Also get rid of the Internet wire too (use WiFi 7 instead of Ethernet), unless you want to use optical fiber (media converters). No copper touching the offgrid rig, follow the "weak link" principle to eliminate any wires touching an offgrid rig. NO copper Ethernet at all, not even the Internet connection. Interference/noise can go over that. Go optical or go close-range WiFi 6E or WiFi 7. Those two are low latency enough for esports.

Most advice is conspiracy tinfoil hattery here.

But the offgridding tip is a legitimate workaround for extreme bad power, grounded (pun) in real science. Some electrical grids are absurdly noisy/bad. Please note, this is no guarantee. Your problems may be other things including the game's own bugs etc.

I want to emphasize that I specifically need online UPS for my setup. The main reason is that if I were to use an off-grid solution, such as a generator or external battery, I would lose the ground connection. Without proper grounding, this could create other issues and invalidate the test.

I also want to clarify that I have already tested different PCs, monitors, and peripherals, and the same input lag persists. One observation I made is that when I disconnect the video cable for a few minutes and then reconnect it, the input lag slightly decreases for a short time, but it gradually comes back and never reaches the same level of smoothness I had before the appearance of the input lag.

Thank you for your responses, and sorry if my English is not perfect I’m using a translator.

Im one of those who tried too offgrid (EcoFlow Delta Pro 3, (close to 3500€), and had same problem off grid (6-7 hours battery mode). Not about ground (have tried byphasical installation and perfect ground on it). Different computers and perypherals, happens too on ps5.

Im actually tring on a room close to main window, ordered an UPS to try it (another post). The only fact that i have now is that Using and testing an AM Radio near cables: The more computer is working worse, the more intensifies AM noise on Radio on that cable and on the house cable that goes to that plug. Sometimes when testing AM Radio Noise and this noise isnt that loud, it works far better.

I heard that an online UPS is not galvanically isolated and that it is better to buy an isolation transformer, so which is better, an online UPS or a transformer? It's a shame that we have to wait to have our message verified.

While usually true:

1. Going without ground definitely does create issues, but sometimes solves issues if your ground was bad anyway. That's a big catch-22.

2. You can connect ground wire of an offgrid setup to a metal water pipe that goes into the ground. Or going to a metal stake hammered very deep into the actual ground. Or the building's lightning post. It would be the only wire allowed. You can read documents by electrician websites about improving ground by using alternate ground sources. So this is electrician knowledge.

3. Use the ground peg of a power outlet (but don't use the power from outlet). Only valid if the outlet ground is good / clean. It can still be way cleaner or way worse, like improperly installed ground, or if there's electrical coupling between the ground and your electricity (creating a noisy ground & problems = safer to go without ground sometimes, e.g. electrical shock in the ground line in the apartment tower outlets that you cannot control). In some cases, the ground peg is clean because it's already connected to the actual ground on your property.

Disclaimer: I am not responsible for the safety of electricity. Before you do anything, study the electricians that talk about "grounding problems". Do online tips at your own risk.

no one. i get 2 in rig, that help a little like 5% for short time.

Hello everyone,

I need some advice. I would like to know if purchasing a ups online pure sine wave can help me completely rule out electrical causes for the input lag.

My budget is limited, so this is only for testing purposes. If you know of a 100% reliable ups that is not too expensive, please recommend it to me.

I can't test my PC in another house, so this is the only way for me to isolate the problem. If the UPS eliminates the input lag, I will then call an electrician to check the electricity

Thank you

Either ups or low cap iso xformer will solve it.
I would say %90 of people here will not benefit from ups
If you willing to buy , buy with lowest output thd (<%2), inverter quality is important , you might get worse waveform than ur grid.

Our problem lies within hf noise (at least mine and most ppl i see here) , low cap xformer with low leakage will not pass those hf (commercial ones sucks , either get it done custom or buy from emc test labs equpiment)

Also you cant drain or conusme hf , you need only that xformer or low imp grounding ( ground shld also be bonded with neutral before entering your home )


If you want to buy custom , i prepared a request mail for it and wrote here , you can find it in my recent posts
