Some KVM switches have a dedicated power input, which helps maintain stable connections when switching between devices. Unpowered models might disconnect peripherals when you switch, which could lead to issues. If you're unsure, you can connect the USB-C port to a USB charger to be. I recently picked up a basic KVM switch to swap between my PCs, and it has a USB-C port intended for power. However, I noticed that it relies on the HDMI cable for power to operate. Is there a risk that the USB-C port could be used for. Why does my KVM switch have a power connector if it doesn't need it? I've got a 2 device PS/2/VGA KVM switch I bought for like 5 bucks in a bin labeled “Misc vintage KVM switches: $5” and I noticed that it while it does have a standard barrel power connector, it functions perfectly fine without it. I'm very new to KVM switches and I've been shopping around for a 2-Port one (Mac and PC) that supports 4K video at 60hz (minimum) and USB3. For more context, I am designing this KVM to be modular such that it will have two seperate. A KVM switch (with KVM being an abbreviation for "keyboard, video, and mouse") is a hardware device that allows a user to control multiple computers from one or more sets of keyboards, video monitors, and mice.
