### ⭐ 







  
  
    Keep looking, failure rate too high!
  

*by K***N on Reviewed in the United States on July 25, 2018*

Terrible quality power supplies.  Out of 18 purchased, 2 of them are bad.  First one died after 2 weeks of use.  Another was outputting 38VDC and fried an internal PSU converter of a PC, good thing the PSU caught the voltage load and not the motherboard, that $40 problem could have been a $180 problem.

    Failed in less than a year
  

*by A***Y on Reviewed in the United States on February 5, 2019*

This item probably won't last for you either. I made sure to get something rated for higher wattage than I actually use, but it didn't matter. Looking for a more reliable product.

    Failed in 2 months, light use.

Failed in 2 months, with light use. Reading reviews today, it appears this is a common problem. Look for a better product.....
