Asus K31CD-UK063T review

  (Rating Hidden)

A big black monolith of a desktop, the Asus K31CD could never be called discreet. With its latest generation of i5 processor and 8GB of Ram, on paper this is a powerful machine. But should you make room for it in your home? Find out in our full review.

Great buy - so far


Had to replace a clapped out computer after six years and wanted a new one that was fast, had all the functions I needed and was reliable. Have only had this about three weeks, but it fulfils all my needs. Easy to set up with good instructions; plenty...

Product seems good. Have not used it to its full yet


From what I have found so far the computer works very well. It is fasy enough for me and what I wish to use it for. There are a few negative points. First the instructions were very poor. If this was the first computer a person bought they would be in...

Not quiet enough


I bought this PC a few days before Christmas 2016. I chose it because the description promised it would be quiet. When I turned it on I was surprised by the whine of the hard drive and obvious fan noise so I left it running for two hours to see whether...

Need PC Knowledge To Setup


The PC is well built. large case is kept cool by a quiet fan. Main criticism is that the instructions are poor in that you need more than a basic knowledge to setup. This became apparent when using the keyboard which is set to English USA thus the @...
