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 Three-Hour 1000-Watt Battery With 3 Power Outlets For Gaming PC
. .
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.
