help with tecs

[saaya]

i have 6 28W tecs, theirdefault voltage is 8.5V, how mayn amps will the draw id i plug them all to my 5v line? how many watts will they pump when powered with 5v?

imma use them on the memory of my videocard...

i have an old samsung psu that has up to 22A on the 5v line, is that enough for 4 of those tecs @5v?

sorry for posting here but the tec section is kinda dead...

does anybody have a good link to a tec formula page?

[saaya]

come on... anybody? any link to the formulas to calculate the A a tec draws or how many watts it delivers with how many volts? :/

Watts = Amps x Volts

:)

should be volts x amps = wattage pumped
so we know they are 28 watt so 28 into 8.5v =3.29 amps per pelt
now 3.29 amps x 5volt =16.45 watts each
:D

cool thx! i wasnt sure about this since there are 80W tecs with a A of 8 and voltage of 16.3v, but i guess those are the max V and A`s...

16W thats 8w for each memory chip on my vidcard... should be fine, i hoope its still enough after i did the vmod on the mem.

thx a lot guys!

typical heat dissipation at def voltage=1W/module! :banana:

not quite, you are saying that the pelt draws 3.29 amps at 8.5v, at 5 volts a different amount of current will be drawn. voltage and current vary linearly, more volts = more current drawn and the opposite. 3.29 amps will not be drawn at 5v, but somthing lower, couldnt help you there, best thing to do is get a DMM and test it. i think it shoult be about 16watts anyways maybe more :x

doesnt matter, the old psu ill stick them to can deliver 22A on the 5v line, thats 5A for each...
