I just ordered these parts:

1 Asus P5B (i965-Core 2-Fsb 1066-Ddr2-Glan-7.1-SataII) € 59,50
1 Corsair 2GB (2x 1GB) 800MHz DDR2 XMS2 € 46,00
1 Midi Tower ATX 400 Watt Black + Front USB/Audio Pc 390 € 39,00
1 MSI nVidia N9600GT-OC 512MB DDR3 + TV-Out + 2x DVI € 127,00
1 Seagate 250GB SATA II 7200RPM 16MB € 47,00
Combined with an old 2.6Ghz P4 Northwood (Single Core)-----till I get some new funds to upgrade that.

But thinking about it I was wondering if that 400W PSU can handle all those components?
This review of the MSI nVidia N9600GT-OC said the power usage under load is about 240, that leaves 160 for everything else. My budget is about 300€ for this one so I'm pretty much maxed out. But I don't want to end up with an OK system that won't run because of power problems.

Thanx in advance!

Sorry about the consecutive posts but wanted to add a last question and since I can't edit....

I have another 300W PSU lying around, if the 400W would be too low, could I use both of em? For instance if I connect the 300W to the N9600GT-OC and the 400W to everything else (or vice versa), would that work?

PSUs that come with cases tend to be cheap crap probably not good for much more than half their label; there may be more than healthy noise and ripple getting through too, which will shorten the life of your components.
According to that review, the ENTIRE system, not just the GPU, pulls 235W under load.
So, that PSU might hold up for a while, but chances are also that when it dies, it will not want to go alone.
Although there are ways to get two PSUs to work together, they involve wiring and soldering. Your best course of action would be to get a quality 400W-450W PSU for your system.

Actually it was probably 240watts for the ENTIRE system. (with OC'd Q6600)

Can you get us more info on the power supply in the case? This wouldnt be a Apex/Supercase PC-390 case with a 400W PSU (that is really a 300W PSU) would it?

Ooh god of course how stupid of me, thanx for clearing that up guys.

This:

is the link to the actual page of the store where I ordered it, as you can see, it does not have much info about it. But with the system used in the review only going to 240W, mine shouldn't even come close to the 400W of the case I ordered.

Thanx a lot guys!
