But are you sure above PSU is enough for my system if i go for 650 ti ?
Currently this is my system:
Cooler Master Hyper TX3 Cooler
WD Caviar Blue 500 GB HDD Internal Hard Drive (WD5000AAKX)
ASRock Z77 Extreme 6 Motherboard
Corsair Vengeance DDR3 4 GB (1 x 4 GB) PC RAM (CMZ4GX3M1A1600C9) X 2
And now i will be adding a GPU - 650 ti which spec says PSU required 450W
