I'm currently ordering the parts for a water-cooled system I'm going to be putting together. While I'm not planning on having a peltier from the start, I'm thinking of later adding one if everything goes well.

Now, looking around, I see a lot about how much power that peltiers need. It appears that some folks say you can just get a "very big" PSU and run it off that in addition to the system...others seem to say that some sort of secondary independent power source is required.

So, what are folks thoughts? And if a "large" PSU is a possibility, just how large (600W?)? I would prefer to buy it now in advance, rather than buy a new PSU later on (or a 2nd power source), and I calculated that my system so far is only going to be using around 400W so far...?

Thanks!
