Ok so I am building a Peltier water cooling system rather than purchase one for $300 as I already own just about all of the parts needed. I will be Using a peltier cooler, a temperature controller that acts as a relay for the peltier cooler as well as turns on the heatsinks fans, a pretty nice CPU heatsink that I have an extra of lying around, and a pump to pump water from the reservoir to a waters block that the is mounted to the cool side of the peltier cooler.
This is the Temperature Controller 12v with a relay current of up to 10A/30V

The peltier cooler is a standard TEC1-12706 12V 92W

the heatsink is a nice aftermarket cpu heatsink I used before I made my own open loop cooling system for my PC. It has 2 120mm fans on each side of the heatsink one exhausting heat off the heatsink while the other blows/intakes air over the heatsink. Both run at 12v 0.16A
And the pump runs at I believe 65W nothing special here.
So the question then comes into how to power it. Ideally I want to run the pump and fans in a parallel circuit connected to the fan relay on the temperature controller and leave the peltier to its dedicated slot but then Im not exactly sure on how to power it. That is im not sure what ampage I would need for the DC transformer would 10A work? I know 10A would not be enough if I ran it all on one parallel circuit but split this way would that be sufficient?
Also last question I was talking to a family member who is in the HVAC industry and he said it would be easier to use an AC temp controller and then use a DC transformer and relays to power all of the devices so that the AC controller is really only acting as the on/off switch for the relays powering the peltier and fans rather than directly powering them.
Any and all help/advice would be very much welcomed as I am experienced with PC wiring and other wiring but have no real experience with having to power something like this and im a bit fuzzy on what type of transformer/switcher I should use or if I should go with the AC temp controller.
Also I feel the all DC option would be cheaper as I wouldn't need to purchase additional relays but first and foremost it has to work.
