PSU questions for AMD o/c

[venm11]

I was considering using my old antec TP430 for my new AMD board for the time being. Will I absolutely need a 24-pin adapter, or can I actually stick the 4-pin alongside the 20?

(I'm planning to run a dfi am2 board, 4000+ dual-core, gf 7900gt (with the 6-pin adapter), 1 hard drive, some fans...)

Secondly.... what characteristics should I look for in a new PSU? From what I can tell, that AMD likes to have heavy amperage on the 5v rail.... and the antec TP2-550 is the most I've seen (40amps). There's also a TP3 out but no specs as of yet.

What do you think, folks? Is an Antec 430 enough for AM2 X2 OC, plus 7900GT?

How old is your power supply ?

There is a risk that a older powersupply has a weak 12v line so it's best to upgrade if it is over 3-4 years.

check out my sig, my powersupply is weak for sure - and i have a dual core opty arriving soonish - just sold an x2 4400 because it was crap overclocking...

I would say get a new psu, but then again I still havent upgraded mine
