    It is an overkill for my son's system but the price was good so I bought it anyways. Only complain is the plugs seem to be backwards. I should have plugged all the cables in first before mounting it. My big hands had a hard time reaching all the slots!!

    Prices are ridiculous for 1000 rated PSUs at the moment. This was just the right price and it's running really stable and well so far. Very satisfied.
