    really good value. 40 bus connectors and enough power that my planned modular of 32 modules eats only about 60% of a single power supplies capacity

    We do not supply the wires with the kit because there is no “one size fits all” solution when it comes to different eurorack cases sizes. Adding cables to the kits would make them more expensive even when you would not be able to use provided cables if they would not fit the case size you are building. That is why all the wires can be purchased separately in our store – you can choose exactly the length you need. A Manual of basic wiring is available in one of the listing photos.

    Quality of the power switch was not the best. The switch is a little loose and some of the contact terminals are too wide for the crimped connectors.
    Bus board screw terminals are a little tight for connecting sufficiently thick cables (0,75 mm2).

  89. Austin C. (verified owner)

    It may be my lazy side talking, but I really love these kits. It’s so nice to get all of your case electronics in one purchase without having to spend a bunch of time worrying about the individual pieces. As long as you’ve determined your current requirements correctly you can’t go wrong.

    The kits are fine. I’m not sure about the spread between +12V (up to 2.8A) and -12V (up to 1A). I probably would prefer a spread of 2.3A/1.5A or similar but I guess that’s a minor issue.
