Would 600W be about right for this setup?
Phenom II 720 BE @ 3.7GHz
Samsung F1 HDD 250GB
x2 4770's CFX
DVD Drive
4 GB DDR2 (2x2GB)
Due to a tight budget the cheaper the PSU the better (PSU needs to be branded though) any recommendations?

It'd probably be slight overkill. If you're looking at a tight budget I'd haul back to ~ 450W which will let you get a better brand and should still comfortably power that lot. Don't forget that your 2 4770s only match the peak power draw of a single 4870!! The only real issue you might find is getting a 450W with 2 PCIe connectors, but you can buy adapters from 2 molex -> 1 6pin PCIe...
hmm using this

it says I'd use 517W at full load, and they don't have a 4770, so I just used a 4870
I would look at getting a modular HX520W or Enermax MODU82+ as these are solid PSUs.
The budgets £50 MAX less would be preferred, and the quieter the better.
Well I find it most satisfying when you have the elegant minimum to get awesome performance, and say a 1KW PSU would just be the anti-christ for me
So would you say a nice 400W OCZ Modular PSU would be able to give enough power to both the cards?
Except that PSUs are at their *least* efficient when put under very low draws: so a 1000W PSU powering a 300W-drawing system is probably pulling nearer 500W at the mains, where a 400W PSU powering the same system will pull ~ 350W.
A little headroom for more components is fine, but since you're most likely to add more memory or another hard drive which won't pull much power you don't need much headroom - maybe 20% / 100W. If you manage to upgrade your computer to such an extent that it's drawing more than double its original power consumption, you're doing something wrong...
If £50 is the absolute top you probably want an Enermax Pro82. If you can stretch the budget a little further, the Enermax Modu82 CAT suggested is £55 and will help keep your wires nice and neat

Would I just need a molex - PCI-e adaptor for the second 4770 then?
