    The power button is on two of the pins on the eight pin power connector. It's the same as the older ATX supplies used, just on different pins. The 6 pin and 8 pin connectors both have three each +12V and GND, plus the Power Enable and GND on those two extra pins.

    Excellent, any pictures and updates on how the upgrade goes is appreciated. I am a bit worried about removing motherboard because I heard it is really tightly fitted in the cabinet. So tips and tricks will be valuable!

    @SeoulFinn Kudos! Very fine walkthrough.

    @SeoulFinn I am about to order a Fractal Design Meshify 2 case. Based on your dissection of the po3 620 do you think the motherboard would fit into a normal atx typ case? What about the dimensions of the weirdly shaped mtb? Are the six screws placed in a standardized way?

    Looks like Acer doesn't want me here. Too bad. Hope you had time to read my reply. So long and thanks for all the fish!

    @GotBanned Oh that is a shame. Your upgrade guides were really good. What policies did you posts violate?

    Now running Noctua NH-U9S and Noctua case fans front an back :-). Followed instructions by @gotbanned / @SeoulFinn . Trickiest part is prying the cpu back plate away. Some patience and a blunt bending instrument worked for me. Scared I would kill the main board while working the back plate but as said it actually worked.

    Good job!


    When I compared my similarly modified  Acer to an unmodified one, the CPU temps(*) the CPU temp difference was "only" 30C. When the unmodified PC's CPU hit 90C in a minute or two it started to throttle and lose performance. The modified one chugged on happily without any loss.

    Tried moving the whole rig to a new case, but as expected I ran in to problems connecting the power cables from the new PSU to my PO3-620 main board. Couldn’t find matching power cables for the ACER Mainboard. There are three separate power connectors at the mainboard, none of them seem standardized?

    shout out; “Anyone who knows how to connect the PO3-620 motherboard to a standard PSU”

    The PO3-620 uses an ATX12VO power supply. As the name suggests the supply provides only 12V DC power to the motherboard via those connectors. An old style ATX supply has a bunch of voltages, ranging from -12V through +12V, with 3.3V and 5V bits as well. Use the stock supply from your old case, they are physically the same size.

    Thx @billsey thats what I need to do. Just hope cable length will suffice. Fingers crossed.

    If you flip your PSU upside down, you'll gain approx. 10cm cable length. Then you still have to figure out how to actually power up your system. :(

    (Sorry to sound like a broken record!)

    I have not given up on the idea, yet... Have not thought about connecting the power button. Is that a proprietary thing as well?

    That's the spirit!

    I can't remember exactly, but unfortunately I think it is. Maybe there is a way to mount Acer's power button to the new case? That is, if it can even be taken off in one piece. But don't worry too much; power button is the smallest hurdle you must overcome.
