This is an "Open Box" Cioks Crux power supply from Sweetwater. It has never been used. I ordered it and realized I do not need it and the return window has passed. It is in excellent condition (basically new).

The CRUX is basically used as an add-on to the Cioks DC 7 and it can be used to power modelers and power-hungry multi effects pedals. The Cioks description is below:

CIOKS CRUX is the ultimate add-on to CIOKS DC7 if you are using a Neural DSP Quad Cortex, a Line 6 HX-series pedal or another power-hungry 9V or 12V multi-effects pedal. Simply connect the CRUX to the 24V outlet on DC7, set the correct voltage on CRUX, connect the appropriate CIOKS Flex cable from CRUX to your multi-effect pedal and you are good to go. 

Using CRUX frees up the outlets on DC7 that would otherwise be needed to run these devices (for instance four for a Neural DSP Quad Cortex and two outlets for a Line HX Stomp), allowing you to run more pedals along with your multi-effects device. CRUX therefore provides a simpler, more reliable setup and gives you more options for connecting additional pedals.
