Gigabyte Superb 460W GE-R460-V1 Power Supply or FSP SAGA II 500 500W Power Supply both are same cost 2.3 k at techshop.in my config - AMD X2 250,2X500GB HDD,3GB RAM,8400GS GPU,LG DVD etc.
I'll choose FSP Saga because I've seen several times FSP used by the overclocker on the competition and I never heard any overclocker use Gigabyte PSU
