Default how many peltiers will run off of 320W?

Sorry, it's probably a simple answer! Right now, I have a Swiftech S320w-12v and am wanting to hook up 2 (80w) and 1 (226w) will this work?

No, the 226w peltier uses all 320watts of energy.

The powersupply supplies 320 watts of energy @ 12v's. The 226watt pelt, MOVES 226 watts of heat (capacity wise), but consumes 320w.

A 226 watt only uses that amount of juice or about 340W if you supply 15V and 24 Amps at Imax and Vmax.

For 226 Watt pelt at 12V, it should draw less current at 12V and have smaller Q max. I would guess it would draw 260-280W at 12V and about 20amps.

I wouldn't use an 80 watt pelt at 12 V.

EDIT: calculations

12v/16V =.8 and .8 x 24 amps= 19.2 amps/
12v x 19.2 amps = 230 Watts draw
