a cheap power supply?

[Uncle Jimbo]

Just to sum up the ides: The 10 psus will be divided into composite units.

The first will be comprised of 6 psus in parallel and power my system (or any other system) by supplying all lines necessary.

The second unit will be comprised of 4 units in series (and parallel) in order to power up any TEC I wish to use.

Correct?

I leave the layout to you. However do not hesitate to use the correct symbols and component layout. I am quite good at following instructions and building circuits from a predetermined plan. I may not understand it all (at first) but I am almost certainly going to be able to build the system....

P.s. Uncle Jimbo, if you could already suggest how many of these relays are needed (http://cgi.ebay.co.uk/OMRON-RELAY-PW...QQcmdZViewItem) I would be grateful. Mail takes forever to be delivered in this country!

Edit: if you feel that a different design is to be considered more desirable, feel free to do a different layout. You have 10 psus on your hands...enjoy!

Well I'll give you two options - one which is a little easier to build, uses fewer relays, and gives most of the capability, and a second which is what I think you wanted to do.

Both of them provide a 'super ATX' PSU with 6 20A 12V rails and better than 50A on the 5V and 3.3V rails. Both also provide 80A or more for the TEC supply.

You will need to do a little tinkering but nothing that should give you a problem.

The 'simple' design uses 20 relays, and the full design uses 32 relays.

This is a pretty exciting project, I think I may have to build one myself!!

Let me know if you have any questions.
