    Question Upgrade G20AJ (i5-4460 model with 8GB RAM, 1TB HDD and GTX-745)

    Hi, I am new in the forum. I just bought a used G20AJ with an i5-4460 processor, 8GB of RAM, and 1TB hard drive.

    I have just installed a Samsung SSD 850 Pro 256GB plus a clean Windows 10 Pro install and gives the computer a massive increase in boot times and responsiveness.

    I have purchased a second SO-DIMM DDR 8GB (Samsung M471B1G73DB0-YK0 1x8GB) to double the RAM; should arrive next week.

    I would like to upgrade the HDD, CPU and GPU.


    1) Does the motherboard support the i7-4790K? and, is this the best CPU you can put on this motherboard, or would you recommend something better?

    2) I would like to replace the 1TB HDD with a 12TB HDD, has anyone experienced any power/compatibility issues doing so?

    3) GPU - has anyone tested the RTX 2080 Ti on a similar G20AJ model? does it work properly with the original G20AJ power bricks?

    4) My computer came with only one power brick, how do I know which one I have so I can buy the other one? a link would be greatly appreciated.
