Forgive me, but if you have to ask such questions, you should not be messing with Peltiers. They rarely do any real good but can often do a lot of harm.

Is your 350 Watt power supply a 12 volt power supply, what type of supply is it? (at, atx, switching, etc.)

At 12VCD your peltier should only draw about 3.6A. That is still an additional 43.2 watts that your heatsink has to dissapate. If you dont have too many devices in your system your p.s. should be able to handle an additional 3.6A, but at 12V your peltier is not going to cool even close to the rated delta T.

Look on the side of the power supply and it should tell you how many amps it will supply at 12V.

Give us that number, at first glance I think your P.S. should be able to handle your peltier.

Generally Peltiers have been getting a bad rap because people are trying to cool the chip to 32F or below and on top of that are using watercoolers. I have found from my testing that going below room temperature will not get you much more in performance. If the payoff is 22 MHz (i.e 583 to 605) but the cost is cooling the chip to 32F, it's not worth the chance of condensation, run it at 583 at room temp and be done with it.

If you match a peltier to the chip then you can run at room temperature and not have a condensation problem. Don't go out and buy the biggest peltier you can find. A 40Watt (12V) peltier will cause condensation. A 30 Watt (5V or 12V) will not if used on a [email protected] volts. Also peltiers need a cold plate between the CPU core and the peltier unit. This can be made of 1/8" - 1/4" Copper or Aluminum. Lastly if possible use a temperature sensor on the cold plate so you can know if your going to have a condensation problem and NEVER run without the case cover on.
