Agree with gt_addict so the only solution is to replace the PSU or contact the support to replace the PSU with working one since you bought it from Aladdin miners they should replace it with working one or get a refund.
You can contact them with this email:
info@ald.top or go directly here

● Returns
Due to the special nature of products, once sold, do not accept refund, return.
So you can't get a refund but you can return it to them to repair.
● Machine warranty
The warranty period of the machine is 180 days. During the warranty period, if there is any problem with the machine, we will repair it free of charge.
