My computer is with 'Asus P8Z68-V Pro-Board' had after almost 2 years exchanged (multiple boot processes and crashes). As improved "Alternative" the 'P8Z77-V' is selected. Now again bought a 'B-Ware' board "P8Z68-V Pro Gen3" (All the best!). Not - After installing the boards booted the computer - in spite of many troubles. Therefore returning. To power the motherboard I can therefore say nothing. Overall, my board will not so "valent", beyond the ATX dimensions are smaller, ie instead of 9 screw-fixing, there are now only 6 (ie narrower). This means that important connections, eg power cord, without support !! For PC makers actually unacceptable.
