### ⭐⭐⭐⭐⭐ 







  
  
    Exact Replacement and Quick Delivery.
  

*by R***1 on Reviewed in the United States on June 1, 2016*

Worked exactly as expected and received in 2 days as promised. (Ordered Saturday evening and received on Monday afternoon, Memorial Day.) Unplugged power from the computer, removed side panel on computer and removed 4 screws holding old power supply in place, disconnected wired connections to computer hardware, pulled old power supply and connecting wires out of computer ....new power supply fit exactly into old power supply location and all connectors were the same. Exact replacement for me. Recommend you remember how each connection from the old power supply to computer hardware is attached and ensure your new power supply connects back exactly the same way. Some connections are just press fit while others have a small latch. Inspect each of your connectors carefully first to ensure you understand how the connector works or you could damage the connection. If you are unsure, look at connectors on new power supply to understand how old connectors should be removed. Not hard to do, just need to do it carefully with attention to details.

    Happy with the product and delighted with Amazon

Since all of our wonderful big-box computer stores have all folded in this area, I sometimes have to run around to lesser stores to try to find something that I need.  On Monday evening, I received a desktop with a failed power supply and realized that a replacement was a bit specialized.  After a bunch of phone calls to places within 30-40 miles, the best advice I could get was to "bring it in and we'll see if we can match it.  I went to Amazon, found the specific power supply, paid less than $6 for next day delivery, and it arrived the next day, as promised.  The machine went back into service this morning, working like new.  Why should I spend several hours, driving all over Tampa Bay, when I can sit back and let Amazon do all of the work?

    Awesome communication!!!
  

*by A***R on Reviewed in the United States on January 27, 2011*

I bought this item thinking it was what my computer needed, but alas it was not and my computer still did not work.  I wrote to ask about returning the item and I received an answer within a few days.  Later as I got ready to mail it back and I had some more questions that when I asked they returned answers within a timely matter.  I returned the item and was emailed that they received it and I would be getting a refund check soon which I did.  Great company to work with would buy from them again.
