Is there any plug system for automatically stepping voltage based on the plug design, so people wouldn't have to set it manually? Like say you had 24v as the base, using a plug with 4 prongs gives you the full 24v, a plug with 3 prongs gives you 12v, 2 prongs gives you 6v, etc...
- wtallis 12y agoAlmost all the power connectors used inside a desktop PC have at least two voltages. For example, a hard drive will usually draw from only the 5V and 12V pins, but some SSDs are designed to use 3.3V. The problem with these connectors is that they usually aren't designed for many plug/unplug cycles. The SATA power connector is also nearly unique in being designed for hotplugging by ensuring that the ground pins make contact first and disconnect last.
