Dedicated PSU for Pumps and Fans?

[squick3n]

I currently have my pumps and radiators stored below my computer in a cabinet. It lets me use a SFF case while also having the whole thing virtually silent. Only hangup is the cables running out of the case are visible. To prime my pumps I use a spare PSU and jump the 24 pin. I'm curious though if that is something that could work full time. Quite often when jumping the PSU I have to reset the paper clip to get it to work. Is anyone using a separate PSU for his pumps? I'd appreciate any insight or tips. Thanks!

Thanks!Well, sure you could use a separate PSU for your pump. I'd prefer to use a molex pci blank plug thingy 128718

and use an extension to get power down to your pump/fan(s)... Maybe something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16812311002 and/or this: http://www.newegg.com/Product/Product.aspx?Item=N82E16812706030

thanks for the links. That definitely looks better than just running cables out an open PCI slot. But I'm not sure I can run 6 fans and two pumps off a single molex plug split multiple times. Right now I have two molex extensions running and a 3 pin coming back to give tach to the CPU fan header. I'd rather have a cleaner look and just have the single tach line going from the case to the cabinet

I have a feeling that you should maybe look at a dedicated cabinet psu. Obviously I have no clue of your power requirements but as an alternative to a computer psu I am leaning toward something like this;

I am using a dedicated fanless PSU for pumps, fans, controllers and such. Got myself a Seasonic unit for this, but any good low power unit would be good.
I also have a cable running through with a power plug adapter so i power up both PSUs at the same time.

@OldChap I have looked at those before. They can't really handle two pumps.

@gmat Do you mind telling me what power plug adapter you are using?

Here is one that will work.

I am using one just like the one BMSliger posted above. Does the job.

Thanks for the info. That looks like what I'd need if I go that direction.

I use this to run pump when filling loop etc. but I guess it could easily provide power for couple dozen GT AP-15's as well : http://www.aquatuning.us/product_info.php/info/p11968_Phobya-external-PSU-230V-to-4Pin-Molex-90W-including-Euro-UK-plug.html
