@campo007 Don’t buy low quality things that may set your house on fire.
The router doesn’t need that great of a linear PSU. Something like this Topping unit should be ok.
If you need to do a streamer or DAC with a linear PSU, don’t get any lower than this KECES unit for $550. It has 2 outputs and you can vary the output voltage for your use case, i.e. has more utility. Or you can try the KECES P8 for $900.
