At the Computex show, TechPowerUp took some photos of the SeaSonic Connect device. This product is basically a PSU connection hub, it promises to make cable management a little easier by routing all the cables to a ruler-shaped structure that can be mounted behind the motherboard tray (provided there's enough clearance there). The first SeaSonic product with Connect could be the Prime GX750 PSU.
Shorter-than-usual modular cables handle the "last-mile" connection to the various devices. A single ribbon cable runs between the Connect and the PSU, with high-capacity wires for the various voltage domains (+12V, 3.3V, 5V, etc.). Those into PSU cable modding would be breathing very heavily. The upcoming Prime GX750, an upper-mid range model with 80 Plus Gold chops, could be the first to implement this concept.
