Hi, sorry if i have posted this in the wrong forum. I tried to find the right place to post this.
I have just recently built a HTPC with the following components.
Case - Streacom FC1 EVO
Motherboard - MSI A88XI AC MITX
PSU - 160w PicoPSU Bundle (with 150w Power Brick) < Link Below !
Cpu - A6-6400K 4.1GHz FM2 Dual-Core (64W)
CPU Coller - Noctua NH-L9a
Ram - 1x 4GB DDR3 1866 MT/s (PC3-14900) CL9 @1.5V Ballistix Tactical
HD 1 - WD 1TB Scorpio Blue (2.5")
HD 2 - Hitachi Travelstar 640gb (2.5")
Case Fan - 1x Fractal Design 40mm
Installation of all the components went a breeze, i booted up with the bios set as factory defaults and installed windows 7 !
After windows installed i noticed the ram was running at 1333mhz so i changed it in the bios to run at 1866 (This is the only change i made in the Bios) I rebooted back into Windows and performed a windows update and 20 mins into the update i heard a loud pop, i checked the system and tryed to boot up only to find the system wouldn't power up !! i changed the fuse but it didn't make a difference the brick was dead !!
Its my first HTPC build using the PicuPsu & AC adapter and i'm hoping someone hear can shed some light on why the adapter would blow up ? there are no loose wires in the case and everything is connected up the way it should be. Does anyone have any ideas as to what happened or anything i can check to find out what happened? I really don't know what i've done wrong or what i should look at.'

Lastly, these forums in general are not really geared towards troubleshooting PC problems, but there are not a lot of eyeballs in the Linux HTPC forum, you might get faster reponses posting in the http://www.avsforum.com/f/26/home-theater-computers forum...although really you should be posting in a PC hardware forum, since your problem isn't really related to AVS at the moment.
Here's what picoPSU support says on the subject:
"The DC barrel style jack supports up to 8A but if you can use a bigger AC/DC adapter if you don't exceed for too long the rated input. Usually, the bigger AC/DC adapters are delivered with a a 4-pin mini DIN connector for higher power. They can also be used with the PicoPSU-120 but with the P4 type connector. For example, see this AC/DC adapter which is delivered with the 4-pin mini DIN to P4 adapter: http://www.mini-box.com/12v-12-5A-AC-DC-Power-Adapter . Hope this information helps!"
I don't know if this was the issue. It was probably a bad AC brick. But, it's something to consider. 12.5A is over half again the rating of the jack.
