I'm planning a pc build that's gonna draw about 400w. however the psu that i have in mind to buy is a 850w gold rated psu. is it bad for the pc if i have a few hundred watts from the power supply? or does it not matter how many watts the psu can support? i would be very grateful for an explanation :)
 
Solution
It really doesn't matter. Efficiency can be affected, but it really doesn't matter, and could actually mean a longer-lasting unit possibly. Quality of the unit itself is most important, though.
Over doing it never hurts if it's a high tier psu. You will still use more power if the psu is capable of more, regardless of how much it needs. But no, it will only hurt your wallet.
 


ok thx :)
