Looking for a very small PSU

post #1 of 9
Thread Starter 
I'm looking to mod something and I'm almost sure I'll have about 3" x 6" x 2.5" to work with, with some other room available but not 100% sure yet.

It will be powering a system in total no more than 100watts max. Needs 20pin and 4pin atx and will need at least 2 4pin power connectors.

I realize I won't be getting any normal ATX power supply that size, and expect to have to take one apart and arrange things inside the thing I'm planning to mod. Perhaps I will even rework the metal for shielding and airflow after I figure a way to fit everything.


Does anyone know of a small PSU maybe with 2-3 small PCB's instead of one too bulky for my application?

Or does anyone know of small PSU's for this type of application?

PS, I looked into some very small dc-dc with ac-dc converter, seem to be about the size I'm looking for but don't seem to have the 4pin for the motherboard or the 4pin's for drives.

Thanks!.

Just came across something a lot cheaper, and I think I could get it to fit.

You can also get a DC-DC convertor and an external power brick.

I have a half-size 150W PS I pulled out of an HP computer. Should fit your needs. I can let it go for just the cost of shipping. Works great!

PicoPSU 120...I own one, just get a 110W AC-DC brick from the same supplier, you're all set. They even have a model that has a 4-pin P4 connector soldered to it. Or you can just get an adapter like I did. Even though it's only 20-pin, you can plug it right into the 24 pin motherboard header.

Thanks for all of the suggestions, looks very promising. I was reading and apparently the one I'm looking in getting comes with an adapter, which would have made the process of finding one of these much easier. Thanks.
