Complete and utter nonsense. A UPS is an Uninterruptable Power Supply, not an Uninterruptable 'Controller'. The only function it needs to meet that definition is to provide electrical power in the absence of mains power. It doesnt need to control anything, or do anything else, and there's nothing on a motherboard that a UPS is designed to control.kingozrecords wrote: ↑Fri Jul 30, 2021 12:24 pm A UPS can control what it's governed to control and what a motherboard is designed to provide for a ups to control.
Some UPS have additional functionality (basically a serial port, usually now that allow them to send a message that can be understood if the requisite service is running on the OS of the computer to shut it down, but the UPS doesnt control that, or the motherboard.
No one has even suggested that except you, when you specifically mooted that a UPS would need to be connected to an individual card.There's no magic device allowing a ups to also control a pcie card's functions too, or power provided in 98% of cases.
And that was a completely nonsensical suggestion, as everyone else here has said, based on your complete failure to understand what a UPS is and what it does.
A UPS ensures that the PSU still gets power if the mains supply fails, nothing more than that. That means there's still power to the motherboard, which means there's still power to the devices connected to the motherboard.
Noone except you has suggested that PSUs do, or need to do, anything with regard to the individual devices connected to a motherboard, because if the motherboard still has power, so do the devices.
The core functionality of a UPS is to make sure that power is maintained to the PSU for a certain minimum amount of time, thus powering the motherboard (and thus the devices connected to the motherboard) for that time. To the PSU, and the motherboard, and the devices, being powered by a UPS is exactly the same as it is when the system is normally powered.
You know, exactly like a laptop running on its battery.
And since there's no instantaneous power drop, that's why its protection for SSDs
There's no mystery about this, no need for stupid notions of powering devices individually. Its very very simple; a UPS provides power just like the mains does, in the event that the mains drops out.
Anything else it does, power conditioning, or sending messages over serial or USB in case there's a shutdown service or daemon running, is secondary.
As to your half-understood snakeoil about batteries and capacitors on PCIe SATA card or whatever; modern SSDs actually have mechanisms in place to mitigate loss of data on power loss, including internal capacitors, and firmware solutions as to how changes to the data are stored.
Good, because you're the one who made up that flight of fancy in the first place.That's just impossible science fiction and a flight of fancy, I will not discuss it further.
