Hi i have unknowingly tried to power my 7U performance case with Meanwell GS90A24-P1M instead of GSM90A15-P1M that comes with the Intellijel Case. the modules were blinking and now the Intellijel Case cant be powered on. Have i just electrocuted my 600€ case? 
It’s probably blown something on the power supply, it is not designed to handle a 24V input. Email support@intellijel.com and they can help you out.
