Trying to activate a "Dell N305P-00 power" supply outside a computer.

I tried the solution given in http://aphnetworks.c...paperclip_trick

So it is not exactly the same but anyway. I connected the green cable to the black cable next to it.

Now I probed with a analog multimeter ( black connected to the green-black combination) the other cables on the 24 pin connector and some other loose connectors.

Nowhere I can find a 12 V cable with the red cable of the multimeter

I would like to use the 12 V connection for a small fan and waterpump (hydroponics on the cheap)

Any suggestion are welcome!

Yours Teunis

Welcome to APH :)

 

Why don't you just buy a small 12V AC adapter? You can just wire it up and make things simple. 60W units are quite common.

I like to use a 110V AC -> 12V DC adapter

For example I have an adapter specs are 12V 4.5A so the current to the fan is 3 times higher tan the specs

on the fav 12V 0.6A

Will the fan blow up?

I appreciate your advice but I like to experiment

Yours Teunis

Nah, current is just drawn on-demand. The current on a power supply indicates the maximum it can supply. The voltage is the one you need to match with specifications.

OK Thanks.

Is there anyone around that knows about the PSU

(See my first message)

How can I activate the 12V connectors?

:) Welcome to APH.

 

Why don't you use the paper clip trick and connect your fans to the Molex? That has 12V output.

The Molex connections don't have power.

I stop working on the PSU

Thanks for the reply. Discussion closed

No problem. The Molex should have power though. Have fun!
