Power supply for 3770 OC to 4.1Ghz, SSD, HD, Nvidia 730 or onboard graphics

Hey,
I'm currently using a 850w power supply but going to retire the machine to either Linux or just general playing about with so going to remove the quality power supply (Seasonic Platinum) to use in my new PC when I build it.

What power supply will be fine for the following?
3770K running at 4.1Ghz, 1xSSD, 1xHD, Nvidia 730 or onboard graphics(probably onboard if I only use a 1200p monitor with it.

I was thinking 450watt?

Thanks for the input. I'll likely go with the Superflower HX 350 or 450. I think 350 will be enough.
