I'd like to use a peltier system to cool both my GPU and CPU; I was looking at the Swiftech units, and trying to reverse-engineer them so I can make it myself a little cheaper; if not that I'd just get their GPU and CPU waterblock/pelt combination units and do the rest myself. Anyway, they sell the meanwell S320-12 PSU; and looking at the specs it looks like it does 25a @ 12v? I'm assuming this would only power one of their 226w 25a pelts. First question: Shouldn't the PSU produce a little more amps than what the pelt is rated for, or should they be equal?

Now I'd like to run another 80w/8a pelt for my GPU; can I wire it in series with the CPU pelt? If so, how do I figure power requirements? Is it as simple as 8a+25a=33a, so I just need a PSU capable of 33a? or does running them in series make it a 24v circuit?
