That said, there's often little innovation in this market. Which I often think is a shame. That's why I was delighted to come across this article, which reviews the Ultra Product X-Connect 500 W ATX Power Supply, a true innovation in modular PSU design.
Rather than having a bunch of power cables sprout forth from your PSU like some ugly weed, a modular design allows you to connect only the cables you need to the PSU. Cable clutter is greatly reduced and airflow enhanced. All serious modders should take a look.
