I might accept the premise that inflation is higher than officially reported, but I don’t accept the relevance of your evidence in support of that premise.

It doesn’t have to be the main GPU. I’m not even sure it would be possible to pass through integrated graphics. But if all you need is HDMI output, you can use the absolute cheapest GPU you can find (assuming there’s an open PCIe slot). PCIe pass-through does require CPU support (Intel VT-d or AMD-Vi) on the host and may need to be enabled in the BIOS/UEFI. I have an NVIDIA Telsa card passed through to a VM on my Proxmox server, but I’m only using it for compute; my card doesn’t even have a video output.

The primary concern is switchover time. A purpose-built UPS can switch in about 10 microseconds. Those large “solar generator” battery packs switch in about 30 microseconds. That might be fast enough, but it’s not guaranteed to be fast enough like a UPS is.

UPS batteries are only rated for a few years’ use, so you probably are due for replacement.

I’ve heard people express the opinion that society is likely to collapse in the next several decades. If that’s a genuinely held belief and not just an edgy thing to say, then saving money for a future in which that money will be worthless makes no sense.

I agree there are people who get into trouble with credit cards, but 99% sounds like a made-up number.

Do you already have a rack? Rack servers are an inconvenient size and shape except in a rack.

But it can draw more current than the line is rated for. Everything electrical is about “can”, not “will”.

Divide 3000VA by your line voltage to get the required amps. Here in the States, I’d need a 30A circuit at 120V and would absolutely have to run a new line from my breaker panel.

Liftmaster and Chamberlain are the same company, so it’s highly likely (though not guaranteed) that the parts are compatible.

I recently replaced my opener in a similar situation. Mine’s chain drive and I did reuse the existing chain. I’d be less confident reusing a belt; rubber degrades faster than metal. But, based on my experience, replacing just the belt or chain isn’t much harder than replacing the motor unit. I had to loosen my chain considerably in order to get it around the new motors sprocket. At that point, it would have been just a few more turns of the tension screw to fully remove it.

::1 is a compelling alternative
