Like he was saying, it's more than just power loss. It's a way of "sanitizing" the power as it comes in. This is "usually" not a problem. But dirty power is arguably worse than power outages. If the voltages fluctuate or get low for whatever reason that puts a big strain on your power supplies.
This could happen because you run a vacuum on the same circuit and your house is old, guy down the street electrocutes himself or the power coming in from the electric company is 'dirty' because they have an issue with transformers or up stream somewhere. It can be imperceptible to you, but your tech notices.
GPU with a ton of vran is what you need, BUT
An alternate solution is something like a Mac mini with an m series chip and 16gb of unified memory. The neural cores on apple silicon are actually pretty impressive and since they use unified memory the models would have access to whatever the system has.
I only mention it because a Mac mini might be cheaper than GPU with tons of vram by a couple hundred bucks.
And it will sip power comparatively.
4090 with 24gb of vram is $1900 M2 Mac mini with 24gb is $1000
