If your free at 8pm will try it out then, I have built many systems, none of them require the force this board required for locking plate, you can hear a noise which sounds as if socket it being lifted up from board, scary, will take out cpu and put in again..
Also what happens if you boot with no gpu and no ram, and no gpu but ram..
as I want to make it as easy as possible I have 3 branded PSU's, the one I used was Seasonic X Series 750W, same as the rebranded corsair.., funny enough built 3 amd systems last week, all different mobo's and none of them booted... maybe it is just bad luck as every system I built in the last 10 years worked..
Tried Zalman and Seasonic PSU, will try another Seasonic, and reset CPU but I highly doubt it is not in properly as I lined up two notches, also what happens when you boot with no CPU?, does system switch on?
I have not connected any cables from case, using power switch directly on motherboard..
Tonight will connect following to board only
atx power/cpu power
cpu/1 ram stick/gpu
have spare memory, psu, gpu, so will change around and test again
