Core i5 overclocked bundle - how much power?

[lazyvulture]

Hey, I'm looking into purchasing the core i5 overclocked kit from this website

(http://www.overclockers.co.uk/showproduct.php?prodid=BU-012-OB)

I'm on quite a tight budget and I'm looking to cut down where I can. I'm quite aware that I don't want to be cutting back on PSU quality, but if I can reduce spending extra on unneeded wattage, it'd be awesome.

Here's the planned spec:
-The linked bundle
-Samsung F3 1TB HDD
-GeForce 210 512MB
-2 x case fans

Was wondering if this corsair 400w (http://www.overclockers.co.uk/showproduct.php?prodid=CA-017-CS) would do the trick?

Thanks.

Ah, I meant to put this in general hardware, sorry.

And how much would it change if I were to step up to the 4GHz i7 920?

400 should be fine i believe but im not 100% sure
