Is a 450W Corsair enough? (working on a budget)

I've got a pc that I want to overclock:

E6400
Ati 4850
Asus P5B
2 GB PC2-5300 Transcend
Chieftec 400W PSU
1 HDD 250 GB WD Sata II
2 HDDs external
1 dvd rom
1 dvd rw
Win XP home

Before overclocking though, I would like to make sure, it is properly supplied with current and that it has adequate cooling. I am working on a budget and I am not going to buy anything to transfer to a new system sometime in the future (right now, I am simply trying to extend the gaming life of my PC while waiting for 32 nm, Windows 7). So, is a Corsair 450W enough for moderate overclocking (I would be happy if I reach 3.0 GHz)? Buying anything more expensive and I might as well buy a E7300 to put in there, without cooling the case and without getting a better power supply.

So, what do you think?

I think you'll be fine with the Corsair.
My wife's system;

E4300 oc'ed to 2.4
8800GTS 512 overclocked
Asus P5N-E SLI
2GB Ballistix PC6400
1 WD 160g SATA Hard Drive
1 LightScribe DVD/RW
1- 120mm fan
2- 80mm fans
Antec 380w psu

280 watts shown on the Killawatt meter when running Orthos and Furmark, equals about a 230 watt load on the psu.

That's good to hear. But your answer got me thinking. Do you think I can even keep my old one?

Personally, I wouldn't trust pushing the Chieftec.
