Is Seasonic M12II 520W sufficient for i3 2100, ASUS H77-M, ATI 56xx series (cant remember exact model), 8 GB RAM, 1TB Hitachi SATA2 HDD, 128GB Corsair M4 SSD? I ask because I just replaced my ASUS H67M ("bricked" BIOS) with Gigabyte H77M-D3H, then encounted problems like fan start and stop soon after. Returned to shop and probably changing it with ASUS H77-M. So want to ask to confirm
