[Power/EMI] I discover why sometime PC become fast and low input lag and otherwise feel high input lag

[Chief Blur Buster]

If you live in apartment you are basically fu**** until someone comes up with solution, power company or neighbours depending on source of the issue decides to do something or you hire some power quality specialist who works for big companies.

You missed my earlier solution, so here’s my Ultimate Pitch. In situations where you have traced your issue to bad electricity (rare), there’s an Ultimate Solution already that is 100% apartment safe.

Apartment dwellers can use lunchbox sized lithium battery that can double as a UPS. It outputs up to 1000 watts, and has a capacity of 1000 watt-hours.

These are camping batteries but they are also perfect for offgridding a gaming PC in a location with hugely problematic electricity (sinewave distortions, massive over-the-wire EMI, nasty harmonics, etc).

A typical single-GPU RTX gaming PC consumes about 300-500 watts including the gaming monitor. Mine eats approximately 400 watts with an RTX 3080 and a 1440p G-SYNC monitor, at non-overclocked settings. This specific battery can output up to 1000 watts, so this wattage is no problem. And it can output 1000 watts for 1 hour, 500 watts for 2 hours, 333 watts for 3 hours.

For a 1000-watt-hour battery you get between 2-3 hours of playtime completely unplugged from your electric company.

RTX 3080 Desktop PC + G-SYNC Monitor Lasts 2-3 Hours On 1000-Watt Battery

These new modern tote-along camping batteries have Tesla style lithium batteries inside them. So it certainly successfully blasts out enough wattage to run a full-tilt desktop gaming rig, with power far cleaner than most power companies.

It gives between 2 to 3 hours of battery life for a full-throttle game computer running Cyberpunk 2077 at maximum graphics detail on an NVIDIA RTX 3080 card (I have their reference card), plus a typical 24-27” gaming monitor. Goodbye electric company, and no generator fumes.

It costs about 1000 dollars but you can tote it along anywhere you want to set up a gaming PC in the middle of nowhere, or even to say goodbye to your power company for the duration of gaming.

The power station can be charged by any dirty electricity and it will output ultraclean electricity. This can be viewed as one way to purify your power company’s electricity — charge it by your existing electricity, then unplug, and game off clean electricity if your computer is exhibiting clear side effects from your power company’s electricity.

Or, it can also be charged from a car socket, or from an inexpensive solar panel; it has a built-in micro-inverter, so you can direct-feed a solar panel into it. Creating your cheap entry-level solar system that can also be used for other purposes such as camping whenever you’re not trying to use clean electricity at home.

These Jackery’s output true sine-wave inverter that is ultra-clean, no matter what good/bad electricity it was originally charged by. It’s the ultimate perfect electricity filter of sorts (in a manner of speaking). Kind of a blunt hammer brute force solution, expensive but super-easy solution.

UPS On Steriods That Powers For Hours

Easiest offgrid desktop PC solution as a “UPS on steroids” that gives usable playtime! I don’t need this as my electricity is reasonably good, but this is an offgridding solution that does not require modifying your apartment!

Sometimes it’s just easier to offgrid with a massive battery as a sustained unplugged UPS, than try to fight a power company’s defective electricity with regulators, filters, conditioners, etc — especially when you don’t know what’s wrong with your power company’s electricity.

All the large Jackery Power Stations support passthrough power, so you can recharge your Jackery while keeping your desktop PC connected. It just behaves like a ginormous massive UPS. You’ll want to unplug from the power company whenever you do things that need clean electricity (e.g. reliable gaming).

There are other situation-specific solutions that may help (e.g. Spread Spectrum, fixing your building’s electricity) but this is a universal clean electricity catch-all — it’s a BYOE (Bring Your Own Electricity).

You are essentially your own power company for 2-3 hours of offgrid desktop gaming PC — yes, it is pretty much a shotgun brute force solution — but it completely sidesteps your electricity problem on one easy (Albiet expensive) try. And it’s useful too, if you get lots of blackouts or you frequently go camping — a takealong power station makes you the envy of your neighbours.

IMPORTANT Note: Won’t fix over-the-air interference issues. This only fixes bad electricity / over-the-wire EMI. It won’t fix over-the-air EMI/EMF like living under power transmission towers. Mind you, this is a “less than 1% population” solution for unsolvable dirty-electricity from your power company.

Thank you chief i would also like to add that a simple am radio that costs no more than 15 dollars can confirm if u have interference or not (it will sound very staticy) before u drop a k on this u should at the very least confirm wether or not u have an issue with interference

there is out there a power station with more power ? 3 hours for me is short time hehe

[dervu]

3 hours is rookie numbers. For some it might be electricity, for some RFI. There are different experiences, but noone yet locked any of it for long enough time to tell if it is fixed permanently.

[BigDog7]

I think you can build solar system for much cheaper

- 180w Solar Panels are around 150 € each you can find it even cheaper if you search more
- Controller 15 €
- 300w Inverter with pure sine wave 150 €
- 100Ah AGM deep cycle battery around 100 €

We already have solar panels but if you include it will not be more than 500 € and for me few hours is enough per day. I'm gonna be buying these parts over the winter and have everything ready for spring and summer including mounting these things on the wall and cable managment so it look good and clean

Yep, I agree. However, it's not an overnight fix -- you can get a Jackery with Amazon Prime shipping and be offgrid tomorrow.

Also, it is illegal in some jurisdictions to DIY electricity without taking a class to certify you as an electrician first (e.g. you have to use a licensed electrician in Quebec, Canada). The Jackery doesn't require you to be a licensed electrician.

Mind you, it is legal in many countries, if you know how to DIY electricity (things like installing a new power outlet, or a new circuit breaker), definitely consider it as a possible option. Where I live (Ontario, Canada) it is legal to do basic DIY electricity like that, as long as you buy proper rated parts (e.g. CSA / UL listed, etc), and I've done a few wiring jobs myself (not for offgridding though).

Thank you chief i would also like to add that a simple am radio that costs no more than 15 dollars can confirm if u have interference or not (it will sound very staticy) before u drop a k on this u should at the very least confirm wether or not u have an issue with interference

Caveat: While an AM radio can be a tool for testing EMI/EMF, sometimes there are bad electricity waveforms like distorted AC-crossing events (squiggly sinewave) that sometimes aren't easily diagnosed on AM radios. There are billions of different ways that electricity can go bad enough to create issues with a computer -- that don't have any effect on AM radios. Some stay-on-wire EMIs don't emit strong enough interference over the air to make an AM radio notice amiss. But if you *do* hear really weird sounds (other than a normal AC buzz) with the radio near wires (but away from other gadgets), then it's certainly one of the many legit redflags you can to add to the redflag list (sometimes you need multiple redflags to reliably diagnose).

That's why it is almost impossible for most average users to reliably troubleshoot. The professionals use many troubleshooting methods, like wide-band oscilloscopes and waveform monitoring / logging (as the waveform can distort at different times of the day -- e.g. nasty harmonics during evenings only, or during daytimes only, etc). Even that doesn't catch everything, unfortunately.

However, if you notice your latency drop massively when offgridding (I've heard of reports in multiple tens of milliseconds), then you only care about the result, and just did a very easy brute-force troubleshoot by temporarily running offgrid off a UPS. So buying a cheap ~750 watt UPS (short duration power) and then unplugging the UPS to test for 5 minutes of offgrid, to see how latency behaves. That can be another troubleshooting method; using a much smaller UPS.

3 hours is rookie numbers. For some it might be electricity, for some RFI. There are different experiences, but noone yet locked any of it for long enough time to tell if it is fixed permanently.

Suuuuuuure, yes it is rookie (not the point), but it's easy.

For a $1000 budget it's hard to get more than 3 hours. To someone who rents an apartment/dorm, $1000 is a lot of money but not as expensive as, say, a Tesla Powerwall style sytem. Or even the knockoffs at half those prices.

If you can increase your budget and do lots more work, and get a real Tesla PowerWall style installation -- then the sky's the limit.

However, it's an easy $1000 quick-solve that is 100% apartment rental compatible and 100% landlord safe for a student dormitory.

One Amazon Prime shipment later and you're offgrid instantly without rewiring or custom setups. It's not much gaming time, but if you cannot spend more than $1000 and you live in an apartment/dorm/etc... It's a way to (semi-inexpensively) go offgrid even in a student dorm this way; which is the precise point -- it's a landlord-safe method of offgridding.

A more advanced DIY solution: You can buy up a few LiFePo4 batteries, plus the necessary inverter/charge controllers -- and wire your own apartment-friendly DIY setup at a bigger wattage (2000-3000 watt-hours) for less per watt hour than a Jackery. If you don't mind waiting 2-3 months you can buy off places like Alibaba and get it shipped by a freight forwarder (ala slow boat).

And could be great if you live in certain countries (China) and have access to cheap domestic LiFePo4 battery packs, which are much safer than Li-On or Li-Poly batteries. But LiFePo4 battery packs sometimes look industrial or looks like ugly car batteries. And starts to become an industrial size/scale a landlord may frown on, unless you box it up in a nice innocent casing/pushcart/etc that blends in your place. But, this would be your route if you didn't mind a roll-your-own DIY solution rather than a rookie solution.

LiFePo4 = Lithium Iron Phosphate
- Very cheap at only a few hundred per kwh!
- Heavier but Safer (ideal for offgriding)
- Doesn't catch fire easily
- Tolerates deep cycling
- Does more charge-discharge cycles (thousands!)
- No conflict minerals

Middle Option: 5 kWh generic clone of "Tesla PowerWall" for ~$2000-$3000 for all-day gaming

You can get approximately 5 kilowatt-hour lithium battery (cheap Tesla PowerWalls for you!) for only $1500 from Alibaba and Aliexpress including an inverter. Then add the freight shipping as necessary. 5000 kilowatt hour is enough for about ~12 hours of RTX 3080 gaming even with an 55" LG CX OLED.

Generic clones of Tesla PowerWalls now exist with LiFePo4 batteries, if you import them from a country such as China. Do make sure you double check they are the safer lithium batteries.

You just need to do but you're going to have a very jump-the-hoop ordering experience (you have to communicate to them like a business, be patient, because you're buying 1 sample from a company that usually sells them in quantities of 100 or more), and being heavy units, freight shipping is slow rather than 1-day Amazon Prime that you can get a 1000-watt-hour Jackery Power Station literally overnight.

But yes, you can build your own cheap 5000-watt-hour "Tesla PowerWall clone" system for your computer room for only about $2000 if you have enough electrician DIY. Basically a one-room-only "DIY PowerWall on Wheels" that is landlord-safe, for all-day offgrid gaming. This is a bit overkill if you're only 50-50 sure it's your electricity. You'll need to buy a cart and make sure these are very safe lithium chemistries that won't catch fire -- LiFePo4 is what I would recommend for offgridding, as they resist deep cycling (charge-discharge cycles).

Mind you, sometimes it's just easier to test with a Jackery first (smaller investment, quick test), or even a cheap low-watt-hour 750-watt-sustained UPS that gives you about 5 minutes of playtime for offgrid testing's sake.

there is out there a power station with more power ? 3 hours for me is short time hehe

If you want to spend more money and/or more time, definitely yes.

You can build your own "Tesla PowerWall" clone for about $2000-$3000 that gives you all-day gaming from even an RTX SLI system.

Google-Fu for alibaba.com and aliexpress.com "powerwall", "lithium iron phosphate", "offgrid battery"
Example: https://www.alibaba.com/product-detail/ ... 35582.html
(IMPORTANT / DISCLAIMER: SEARCH EXAMPLE, NOT AN ENDORSEMENT, I DONT KNOW IF THIS IS ONE OF THOSE "SAFE" ONES)

These chinese bazaars add things like "tesla powerwall" in their names, even though it's just a cheap clone using chinese-made LiFePo4 batteries. While some chinese batteries are really safe, others have their risks. Do your research, test/inspect, check factory certifications, check ratings like UL/CSA (some are faked, some are real), and get safety precautions. Also, some of them have crappy cheap inverters that generates a lot of interference. Also, you will have to be your repairperson (can't easily money-back). Do your homework!

Solar panels actually generate a lot of interference lol

[Chief Blur Buster]

Solar panels actually generate a lot of interference lol

FACT CHECK: Misleading Anecdote

Solar panels do not directly generate interference significant enough to affect a computer.

But cheap crappy-made inverters do.

Inverters are those devices that convert DC electricity (the type of power a battery or panel outputs) into AC electricity (the type of power a gaming tower PC accepts). So inverters are indeed mandatory for solar panels if you want AC power outlets. That's where the problem is: Crappy cheap inverters that generates lots of interference.

Those shovelware inverters from the bottom of the barrel that generates fake-AC (not true sinewave) with poor power factor correction and becomes a harmonics-generator. You buy cheap panels with cheap crappy microinverters built into them, and they can generate garbage electricity. So yes, you are semi-right that a crappy solar install can generate bad electricity. But that's NOT the panel fault. That's the inverter's fault.

• Some panels include an inverter built in. They are often called "micro inverters".
• Other panels do not (and you buy inverter(s) separately as separate boxes).
• The cheap inverter is the interference problem, and NOT the solar panel.
• Not all inverters generate interference

Moral of the story: Buy high quality inverters when you buy solar panels!

Don't skimp on cheap solar inverters that generate interference.

Although you're right about the inverters, there's no measurements that I'm aware of that show that it's not enough to affect a computer. I mean if it's far away it's probably not an issue but if it's literally right above you, I'm not too sure that I'd take the chance.
