## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    It Works!
  

*by J***H on Reviewed in the United States on March 16, 2019*

I purchased this PSU to upgrade from a 235W unit in an Optiplex 360 Desktop PC.  It arrived quickly and was carefully packed.  The unit was very clean, exactly what I'd expect for the "Certified Refurbished" designation.  I've been using it for almost two weeks without any problems.

### ⭐ 1.0 out of 5 stars







  
  
    NO POSSIBLE WAY TO INSTALL IN A DELL OPTIFLEX 745 AS STATED.
  

*by J***W on Reviewed in the United States on February 27, 2019*

Mounting holes do not match.  Only has one connection that would reach the motherboard intended location.  All other connections are too short.  Would not trust this supplier because the differences are obvious that someone took a guess in sending it.  My first real disappointment in a Amazon purchase.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Perfect fit in OptiPlex 755
  

*by A***I on Reviewed in the United States on July 30, 2019*

Worked great, fast shipping.
