Two MOBOs in one case
« on: January 03, 2009, 06:36:08 PM »

Hi,

In this review

http://www.gideontech.com/content/articles/328/2

they manage to power up two independent MOBOs but there is little clarification up to how they did it. Most 5.25 Bay PSUs (like those at Thermaltake) lack a P4 ATX connector, necessary to power decent mini ITX like those from Intel, and are designed to assist the main PSUs but not to work as main PSU by themselves alone.

My bet for this case is that they managed to put into it two independent PSUs, each feeding its own respective MOBO. One PSU must be in the fashion of a small form factor.

Any comments onto how this could be possible? Thanks.

It might also be an external PSU-- like one of those PicoPSUs which is an external brick which runs to a small card that plugs into the ATX socket.

"Placing the BFG PSU in the case, we can see how much space both of these take up. It's really not all that much, as all of this is behind the primary motherboard. There's still a more than 30cm of free space over the PSU."

Looks like there are two PSU's in there. It seems like a bit of overkill, but a 75W Pico PSU (I got one) requires somewhere in the range of 3.5+ amps @ 12v for stable operation, so I don't know how well a average (500W) PSU would enjoy having to run the Pico on top of a regular system.

2 PSU's One BFG for the Main ATX, the a PicoPSU is used now with a external brick on the mini ITX board.

The PSU on the iTX board was replace since that review to a nicer and better fitting PicoPSU

Thanks for the advice. The pico PSU with the P4 (the 12 volt four pin) adaptor will do the job.
