power source w/ >4A @ 24v...?

post #1 of 12
Thread Starter 
I dont know where to post this considering it applys to air cooling...a radiator, and its a PSU question. lol

Long story short, I have 2 of these-> Attachment 52971

They are high CFM 240mm fans, in a ~260mm enclosure. I am considering using one for 2x BIX2 120.2 rads, or using both of them on a 'dual-quad' heatercore setup.

Attachment 52972Attachment 52973Attachment 52974

Theres a shot of the input specs, ~2.3A @ 24v for full power. Once I have something that can power them, I plan on building a small speed controller setup .

So... is 'meanwell' the only solution for me, for a good 24v PSU, or is there a cheaper alternative? I would gladly buy and mod a PSU, if it will do the job. Currently the extra PSU's I have laying around, do not have enough on the -12v to handle the load.

any suggestions?

I can barely make out the specs on the side of that fan ... does it say 24V 2.14A ?

Just making sure.

If so, you need about 102.72 watts at 24 volts to have enough to run both fans.

( Watts = Volts x Amps )

Here is a pretty good place to get 24V PSU's that are good quality...These are like 3&4 amp models look around they have higher amperage models to..


...24 Volt AC/DC Power Supplies, Mid Power, 75 to 325 watts, Chassis and Enclosed

Here if you have 2 values you can figure out the other 2...

nice, tnx for the link Ira, i think this one, will do nicely. Its only 86$...thats pretty cheap, a lot cheaper than i expected thats for sure.

Q- is 310W enough to run the 2.1A fans and a small TEC..for gpu?

It would have to be an awful small pelt...I would say not..That PSU only has 12 amps..Check the under-volting charts and you can see what kind of amps they pull with different voltages...


...TEC undervolting charts

This guy has different sized ones I have bought several form him with no problems...

Those are the quoted specs for a 120W TEC...

7.7 + 2.1 + 2.1 = 11.9A ... kinda close... but I plan on using a speed controller for the fans to undervolt them a touch..they should only be pulling 2A at start up...what do you think?

That would be shaving it pretty close...Is that pelt a 24V one? You could alway hook it up to start the fans first then the pelt...Do you think a 120W would cool a GPU? I think they use around a 180W on GPU's....I really don't know though I've never done a GPU before...

From the ones I have seen made by swiftech and DD, they vary from 80W-120W...

Maybe I will just get one and use it for the fans for now...I need to upgrade my W/C'ing in a bad way, and want to add the chipset to the loop.

I guess it would work then...Yeah you could always get a cheaper PSU and later on get a higher amp model...They have 15V PSU's there to that might save you having to use a controller on one...They night not start at that low a voltage though I don't know...It would suck to have to spin them with a pencil every time to get them started.......Most of the better ones you can + or - them 10% of the rated voltage, they have a trim pot on them...
