    Hi.

    I have an Ivy i5 and would like to use it in a very slim SFF build.
    Seems like most slim mSATA boards with external power supply can handle up to 65W TDP, like this board for ex.

    Ivy i5 does 77W TDP.

    Any suggestions?

    Get an i5-xxxxS/T. They have 65 or 35W TDP.

    The i5-3475S for example has 65W TDP and the HD4000 graphics.

    I have a 120W 24pin PICO DC supply if that would give me more options?

    If you've got a 120W picoPSU and the i5-3550 allready, then I'd suggest a standard H77 miniITX-board, which are available for $100. The thin miniITX-boards with onboard-PSU and external powerbrick are all limited to 65W and there's only the boards form intel and Gigabyte.

    Ok, thanks. But the H77's I've seen have a p4 socket, and my PICO psu lacks of an P4 connector... Is there a way around that? Steal some 12v's from the 24-pin connector somehow maybe?

    All the desktop intel CPUs require the P4-power-connector. The reason for the thin miniITX not having them visible is the integrated PSU-circuitry.

    So either go with thin miniITX and buy a new CPU with lower TDP or use your current CPU and buy a "normal" miniITX-board in addition to a new picoPSU like the XT150. There's no way to modify your old picoPSU with a P4-connector.

    Why not the P4 connector is only 2x 12v and 2x ground , easily taken from a std molex ?

    Not possible, as it would overload the PSU. The modern picoPSUs have two circuits to prevent this.

    My friend has a Pico PSU with P4, but it's from molex as this one:

    This won't work?

    The thing is I wanted an mITX with onboard power, and they don't support over 65W cpus. But I'm going to get an Intel dh77df and use a pico PSU instead.

    Sorry, I gave you the wrong link :

    http://www.gigabyte.com/products/product-page.aspx?pid=4463#sp
    http://www.gigabyte.com/products/product-page.aspx?pid=4462#sp

    These 2 thin ITX boards, with onboard power, both support 77W CPU. Only keep in mind that the PCIe-4x expansion slot is limited to 25W, compared to the 35W with the Intel boards.

    Oh, that's great news. I'm not going to use the PCIe-4x anyway. I'll go for the GA-B75TN then, thanks a lot Guille!!

    You're welcome. The good thing is that this board is less restrictive than the Intel ones about the laptop brick voltage. It accepts anything from 12V to 19V, where the Intel board accept only 19V brick.

    That's nice, cause I have a 12v brick laying around.

    I've got a Gigabyte GA-H77TH Thin Mini ITX board and according to the website it supports up to 77W chips.

    I can't prove they are right though as I'm running 66W chip.

    Looks like GuilleAcoustic beet me to this.

    Oh well, I should learn to read the whole thread before putting in my 2 pence worth.
