Thank you

- i7 3770
- 2x Radeon HD7470
- 1 HDD 7200rpm
- 2 4gb sticks RAM
- 1 case fan
- 1 optical drive DVD RW
HD7470 = 27W (x2) = 54W
i7 3770 = 77W
The rest is trivial.
So total: 131W
If you overclock lets add 50% = 200W.
Add 50W for headroom.
So I would say you could run your rig overclocked on any good PSU 250W+.
Here is a well made Seasonic 300W for $43 shipped.
