    Plugs and Plays in a Friend's Computer
  

*by M***N on Reviewed in the United States on July 26, 2013*

I bought this for a friend whose power supply went out on his computer. He owns one of those Windows 7, 64-bit, Lenova computers that looks like a toaster oven. I took the old power supply out and put this new one in and he's back in business. It was all just that simple and he's tickled pink because he thought he was going to have to buy a new computer.

    One of two units ordered was bad out of box
  

*by N***S on Reviewed in the United States on June 2, 2018*

One of two units ordered was bad out of box.  Unfortunately, I had the unit for over two months before even opening the box.  This is seriously unimpressive.  I run a technology related company and always order extra hardware just to keep a part I will likely need on my shelf.  Don't count on hardware from this company to actually work once you pull it off your shelf.

### ⭐⭐ 2.0 out of 5 stars







  
  
    Rattles and roars like bearings are worn out
  

*by D***E on Reviewed in the United States on January 15, 2016*

Have had for about 3 months and fan is already going out.  Rattles and roars like bearings are worn out already
