So my computer has been acting funny ever since i got a new psu, including a broken motherboad and videocard. I got a power supply tester and it read the voltage as 5.2v for the 5v connector and 3.4v for the 3.3v reading. is .2v enough to damage the hardware? could this be my problem? if so, can it be solved, through a power regulator of some sort, of msut i invest in a new power supply? thanks!
