I just purchased a new PC with a non labelled case and my question is about the power supply. The power supply is a Kingwin MK-650W 650W ATX. I notice that the power supply has grill near power switch (rear) and a top mounted fan. However, the case does not have a grill on top at all for air intake. please help me understand how this works. The computer store said this was fine. my logic tells me that the fan is useless in this set up. Did they mount the power supply upside down
or did they give me the wrong case?
