After having owned the computer for 8 months in a second home where it was used sporadically for just a few months, the power supply failed. Acer would not pay for my shipping costs so I'm out another $55, since returning it to them was my only option other than junking a $550, 8 month old unit! Great customer relations! NOT!!! I found the following review on Amazon and it describes my situation perfectly. "1.0 out of 5 stars Do not buy if you intend to modifyReviewed in the United States on September 12, 2020processor_description: Intel Core i5-10400 6-CoreStyle: Desktop onlyVerified Purchase"This piece of crap uses a completely non-conforming power supply. All kinds of reviews of how you can add larger video cards, but with this model they have changed the power supply configuration to some little 300W power supply that does not conform to any power supply I have ever seen. New motherboard connections, new size factor - absolutely no way to port over the real power supply I had intended to use. Amazon needs to quit lumping reviews and comments for several different models together as it is very misleading. You want to run excel? Maybe its an ok computer."It will be interesting to see if Acer corrects the power supply problem or just replaces it with the same garbage components and configuration. This experience has been so bad that I'm seriously thinking of dumping Amazon Prime and taking my business elsewhere. A shameful misrepresentation of a seriously flawed product!
