What do you think of this combination?

I really want the stacker because I would like to do some modding on it and will probably convert it into a BTX case. Just out of interest, what case would you take for around the 250$ mark? I might get persuaded.

My real dilema is with the PSU.
I wanted to take the Corsair 620W because some people told me it's a really strong and reliable Power Supply but someone here mentioned PCP&C and after a little research I found out they're really good when it comes to PSUs.

So what do you guys think? The Corsair 620W or the PCP&C 610W? Maybe something else altogether? Max 200$ for the PSU.

That really is a tough choice. You've chosen two PSUs that are truly excellent, and for their price they're probably the best in their respective catagories. I say respective catagories, because one unit is a quad-rail PSU, the other a single rail. In simple terms, the Quad-Rail unit (Corsair) would be the my pick for a SLI/CF gaming system, whereas the Single-Rail unit (Silencer 610) would be better for a server type system, where the +12V load isn't so evenly distributed, or one/two future very high end video card(s), which may actually exceed the maximum load available on any single rail.

As for the best under $200, the Silverstone Zeus 750W or PC Power and Cooling 750 are essentially better versions of the Corsair and Silencer 610 respectively.

What will the unit be powering?

Well the processor will be X6800.
Other parts except for the video card have no effect on the PSU so I won't mention them.

Right Now the video card will be an X1900GT but in a few months I will switch to either a GF8800GTX or wait a little longer for the R600.

I keep reading reviews and the PCP&C sounds like a truely strong PSU.
Can't find much about the Corsair I'm afraid.
 
I already read this review. :D

Man... I don't know what to get but I think I'll go with PCP&C 750W.

On the other hand I won't be getting an SLI/CF but I will have one of those high end, power eating DX10 cards so maybe I should go with the Corsair?
 
The difference between the Corsair and the PC P&C Silencer 610 on the all-important +12V line is only 1A in the Corsair's favour. My issue with the Corsair in this particular configuration is the load-balancing. If a high end DX10 video card, along with other components, is drawing power off one particular +12V line, it could exceed the 18A that each rail is rated for, and the PSU could shut down. Let me explain:

Firstly, here's an image (from Jonnyguru) of the rail distribution on the Corsair:

Note that the +12V2 and +12V3 connectors are each powering a PCI-E power connector, as well as a number of the modular connections. If we assume the video card requires 300W (which is what some of the rumours predict), that corresponds to a load of 225W or 18.75A on the +12V line (mobo can provide 75W). If we've connected say 4A worth of drives/fans/etc... on the modular connectors associated with that line, we reach a total current draw of 22.75A, on a line that can only provide 18A. OCP is triggered, and the unit will shut down.

This is, of course, something of a worst case situation, but is the main reason i'm directing you towards the Silencer, which, due to its single +12V rail @ 49A, will easily handle this load. Do note that the 8800GTX will be powered from two PCI-E connectors, so the load will be split over 2 +12V rails, and we'll still be fine. This will not be the case with all high end DX10 cards, however.
