It has been suggested that the problem could have been caused by the PSU being underpowered for the rig. Out of interest I used the extreme power supply calculator at it came out saying that I need a PSU rated at 298w, hence 430w should be ok.
My question is this - is the PSU underpowered and therefore being pushed too much - hence I need to get a more highly rated PSU?
Is the PSU fine for this rig and I was just unlucky with the PSU unit that I got?
