PicoPSU connector?

I have to power an itx motherboard without the typical power supply option.  


I found this: http://www.ebay.com/itm/PicoPSU-150-XT-150W-12Volt-ATX-Power-Supply-Cyncronix/160429089631?_trksid=p2054897.c100204.m3164&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140407115239%26meid%3D8873486385218778677%26pid%3D100204%26prg%3D20140407115239%26rk%3D2%26rkt%3D21%26sd%3D110888383297


Does anyone know how that works exactly?  What kind of power supply do i need to plug up to that?  Just a standard 12v wall plug ac/dc converter?  Or do I need a specific mA/wattage?

Depends on the power you intend to put through it. Further down their page, you can see they do a bundle with the adapters (like the laptop adapters). Basically 12v times amperage = higher wattage.

If you plan to run the PicoPSU to its limits (150Watts) you shall need a higher amperage device. (12v 12.5Amp)

It depends on how much power you require really.

the full 150 just to be safe

thank you!

What that adapter will let you do is use a more standard single source 12-volt supply to power your motherboard and possibly a peripheral or 2 like a hard drive.

This is an excellent solution for anyone who builds a HTPC using a ITX mobo (because ITX is about as power efficient as it gets) and wants a fan-less power supply to keep things quiet. But it's not a very good option if you have larger power requirements like if you're stuffing a AMD 4+core CPU into your motherboard and trying to do some bitcoin mining that requires some heavy math calculations (which causes said CPU to suck down the juice). And that's because a typical 12V "wall wart" is not as likely to be able to provide anywhere near the same current even if we're talking about a laptop power brick.(The thing to remember here is that It's all about Ohms law.)

BTW, I simply used AMD as an example of a power hungry processor (which often requires more "amps" and thus a beefier PSU) since Intel has AMD beat pretty bad when it comes to power efficiency. But make no mistake, even a Core i7 or something (or even an older spinning HDD) might require a bit more "amps" too/instead (it depends on your choice of components in your rig).
