pretty much anyone can sell you one but get a decent branded one rather than budget, its less likely to blow up and more likely to put out the rated power.
how much are you looking to spend?
but what is a decent brand?
if you are sure 430watts would be enough
if you are sure 430watts would be enough, i'd got for the Corsair CX 430W ATX Power Supply
can get the 500watt for about £50
to be fair it all depends on what you are running - mine is a 700watt PSU and that is fine, any less than 600watt and i'd struggle .
true it depends what you run, but unless its a beast of an overclocked machine with billions of drives and peripherals a decent lower rated PSU is fine.
scan, ebuyer, overclockers, novatech..

Cheers to all concerned, just fitted me a novatech 400w psu, wow its soooooo much quieter than the old winpower one fitted to my unit.
£30 notes !!!
quite impressed by the Novatech store, anyone else use their kit?

Yikes!!! Bog standard PSU!! Hope it is a good runner for you mate. Was it very light or heavy?
Light ones are usually naff. Cheap components etc. Upgrade to a good 'brand' one soon!

we opened it up and found what can only be described as a mini breeze bloke inside![]()
I run my PCs 24/7 and I've had 2 x 450W power supplies die on me within 3 years.
