The new PicoPSUs
At Mini-box.com I saw PicoPSU-120-WI-25V with a 12-25V input and PicoPSU-120-WI-32V with a 12V-32V input. I checked the WI-25V manual and it says 6A over 12V which is more than enough for a mobile on the desktop. And you no longer need to hunt for arcane high ampere 12V bricks, any run of the mill laptop charger will do -- I think the sweet spot is at 19V. 19V 6.3A (120W) laptop chargers are twelve a dozen. And smaller, 4.74A (90W) chargers also equally easy to be had.

Please forgive a question without much research, but how do I work out my 12v amperage requirement? I assume the CPU, HD & optical all draw mainly from the 12V? I have:
I have an NSK2400, and the PSU whines, so a replacement is attractive...
- X2 3800+ 65W, should use well under 65W, but a theoretical max of 5.5A if it took that all from 12V
- 3.5" Samsung SATA drive, up to 1A?
- DVD drive ???

You guys forget about the to 12 V conversion. The original PicoPSU didn't touch the 12 V line.
EDIT: of course, dreed mentioned it first. See my message as a reminder that's more than a 1 % hit.

Try my psu calc, has 12V amps calculations.jimmyfergus wrote:Please forgive a question without much research, but how do I work out my 12v amperage requirement?

I have:If they all draw from the 12V line, I would be done for, especially given that I can't undervolt in BIOS, so at startup I'm drawing full power?
