PSU problem !!Some advices would Nice !!

Hy i'we just registered . read all kinds of stuff for over 1,5 years at TH.
Ok ,my problem is >> is have a crapy 400W PSU that can take around 240W load max ,
My System specs are :
Amd 3200+ venice 1.4v
Abit KN8Ultra Nforce 4 Ultra
1x1gb kingston DDR400 cl3 Ram
Daytona X800GTO (r480core)
Seagate barracuda 7200.9 250gb SATA
SONY CDROM ))
onboard sound /LAN
a modified case and the rest (monitor. mouse ..)
considering that i am from europe .and my current buget is kinda nothing ..... what PSU would you guys recomend ???
I'we put my eyes on a Thermaltake Purepower 430W , or a Hiper Power 435 w , that's all i can afford (hopefully i can ) . some advices on the brand or some other PSU that i should be looking for ,or the output that would work for me (I Won't upgrade in the next 1-2 years!)??
PS I would overclock hard (CPU,GPU,MOBO) , i can't go further than 2.4 ghz CPU the PSU is failing at that load !!

oooh, this is a hard one, but seeing as you don't have a big budget, I'd go for the thermaltake, I know someone that owns one with a 6800gfx card and everything you have, with the exception that he also has a 74gb raptor on it too, I think it may be able to suffice, if you could wait and save up more, that would be the smart move, otherwise the thermaltake is good enough

And I hope you enjoy forums as much as the rest of us do^_^

I think a new psu may do the trick to fix that
