> Higher voltages improve transmission efficiency, in particularly for connectors, as long as sufficient insulation is easy to maintain. Datacenters are looking at 48V for a reason. What datacenters are doing has little bearing on what's worth the replacement and reengineering cost in a SOHO environment. Datacenters have multiple orders of magnitude more power they need to deal with than a SOHO user. Also, given the long-standing existence of the 80 Plus program, I'm also pretty suspicious of claims that switching to HVDC inside the computer chassis will have an effect on a end-user's power bill that's not washed out by the increased expense of the replacement components. Will it? Do you have the numbers? > (sometime connectors even only work once!) I've been building PCs for decades. While I totally believe that there are such connectors, I've never been so unlucky as to encounter one. > They are numerous orders of magnitude more rugged than any internal connector you've used. Some? Sure. Any? Hell no. For example: You cannot honestly claim that a bigass ATX power connector is less resistant to shear force than the tiny wafer that is the USB-C connector. I've had many USB-C cables (and some ports!) fail at the connector end due to stresses that ATX cables handle just fine. But yeah, I totally agree that -say- SATA connectors, or "freestanding" front-panel pin connectors are far more vulnerable to shear and torque than USB-C connectors.
