Seasonic 620W Power Supply (S12II-620) / Seasonic 520W Power Supply (S12II-520) OR Corsair Gaming Series 600W Power Supply (GS600) OR Antec Basiq Series VP550 (550W) The PC is a rather basic Intel Core 2 Duo E7500 with a G41 motherboard. RAM currently 2 GB DDR3 to be upgraded to 4 GB DDR3 Hard Disks - 2 DVD+/-RW Graphics: To be upgraded to HD 7770 Which of these would you recommend for my system?
