I upgraded my 5 year old Aspire TC-780 -AMZKi5. It's been a great personal PC with no problems until a month ago. The 300w power supply burnt out. I found an APEVIA VENUS SERIES 450w PS on ebay installed works great. Well I might as well upgrade the 8gb of RAM. I got 2 8gb ram cards from A-Tech. Twice the Ram I got twice the performance start up and loading speeds. Might as well get a Graphics card since the TC-780 never came with one. I got an ASUS Geforce GTX 1650 OC 4gb. The upgrade has opened the door to the PC cloud gaming world. I lost my optic DVD drive in the process. I've spent about $250 so far and I have heard I need a SSD to make the gaming upgrade complete.
