PSU and comp question

[spongebobfan]

I have a computer case, a small one with a 230 watt mATX power supply: 3.3v=10 amps, 5v=18 amps, 12v=7amps.

I want to put in a

P4-3.0c
mATX intel 865 MB
a gig of 333 ddr
ati 9600xt
audigy 2
40GB 7200RPM HDD
48x cd-rw

Am I asking for trouble? As far as I can figure, the people with shuttles with 200/220 watt PSUs regularly put this hardware in without incident. Is this a safe assumption?

Thanks in advance,

Sponge

Edit: The PSU is new, only 2-3 months old, it has the P4 12v MB connection...

How old is this PSU? There is a possibility that your PSU isn't P4 certified and it might not run your setup. When you hook up everything, push the power button and nothing happens or even possibly the fans comes on but no POST from the main board then you'll more than likely need to buy another PSU.

With all that, I'd definitely be more comfortable with a 300/350 W PSU, but odds are good that you can probably get by on the 230 W.
