One of the more interesting ideas that has been floating around the world of gaming PCs in the last few years is the concept of back-connect motherboards. The principle of these systems is that instead of plugging cables into the top of your motherboard, where they look all messy, you plug them in from the back. However, one of the developers behind this idea has just proposed a new standard that will do away with power supply cables completely, and it's called BTF 3.0.The BTF (or Back to the Future) standard is one of two main competing standards for the back-connect concept in some of the current best gaming motherboards, with Asus the most famous backer of BTF, and Asus' biggest rival, MSI, choosing the competing Project Zero standard. Both concepts broadly offer the same cable-tidying benefit for the handful of motherboards and cases that currently support the two competing standards, but BTF 3.0 looks to take cable clearing to a whole new level.Read the full story on PCGamesN: Gaming PC power supply cables could be a thing of the past, thanks to this brilliant new idea
