Like the title says, I'm curious if i can connect a 24V RGB led strip via usb port of the computer. The strip will have 2.3 meters (roughly 7.2 feet according to google) and it's going to be lighting the desk and it would spare an outlet. I know that I need a power converter like this one https://www.ebay.com/itm/DC-USB-Step-UP-Down-Adjustable-Converter-5V-to-1-2V-24V-Power-Supply-Module-/372704356638, but I'm concerned that if I connect to the computer it might fry the port or the board.

It can work, but you'll likely only be able to set it to a fraction of the brightness before the USB port cuts the power on you.

That would happen because of the low amperage or simply can't handle it?

Just limited power (1A at 5V for a USB3 port), which means 200mA at 24V, plus you'll likely lose 20% of that in the converter's efficiency...

It's better to have an independent plug for the strip then to have a more stable and real 24v 2A other than a power converter to reach those values right?

It's a shame, because it would be interesting to have it. Thanks!
