    Review of Dell PS

    Posted by Cordell on Jul 03, 2017

    Received in good order. Was well packed with plenty of bubble wrap. So far so good. Will let you know as time goes by... BTW I have the old PS Optiplex 755 and another dead one from another Dell Dimension E521- would you be interested? Could ship to you if you want maybe for some credit?? Thanks for the great service!

    ordered for PSU and it came well packed and installed that in no time and my wife did not believe our CPU (desktop) as there was no sound produced while coming up and in working processes.

    Thanks for that great product.
