Oops missed 5770 crossfire so system will use maybe 450 watts instead.
i wont to do an serieos over clock and now i have the 525w enermax, i think it wont be enough.
thats whay i wont to upgrade sow i Thoght to buy somthing that will be good in the future too.
what do you mean -"hurt the efficiency of a power supply" it will ruin him or somthing?
the 525 will be enough for the over clock and for the cross fire?
