There is no logo or other markings. I must asume that they are MOSFETs because of they position and function. After taking of one suspicious specimen (furder measurment showed that there is shortcuts on uper MOSFETs) MOBO start to power on with adition +12V connector present and shortcut is gone.Only I need is datasheet of this 8-pin components.
