    Carnetix 1280 enough ??

    Hi guys, I need your guidance before I go and buy a PSU. I would ideally like to keep the internal PSU so that I can just bring it in the house and use the original adaptor.

    I have a Cubid 2699 case (60w morex ??) with a slim cd drive and 3.5" HDD. Here's a layout of all the components I'm gonna add eventually (got everything except the PSU, unpowered hub and slim drive/enclosure).



    I still don't have power to the firewire drive though... Suggestions... I have a couple of PT6653D chips that I was going to use for 5v supplies. Suitable ??

    For the hubs, I assume the BT and wireless dongles won't be power hungry so no power to that one. The front one is powered as I'm sure I'll end up plugging extra thnigs into that...

    All comments/suggestions welcome.

    The only thing that worries me is the 3.5" drive. Do you know the current requirements of the drive you will be using? Have you already powered the system from the Morex? If so, the P1280 should work fine.
    I still don't have power to the firewire drive though... Suggestions
    You could either power it from the Secondary Output of the P1280 (it's cabapble of at least 3+ amps), or you could add the CNX-P5V regulator that's coming out in June. It will give you an additional 3 amps for your firewire devices assuming they are on a powerable hub.

    I don't know the specs and haven't personally powered it up yet, but it was bought second hand as a complete PC so was working with the internal PSU previously...

    The secondary 5v supply will be going to the powered USB hub.

    I saw a post about the P5V, but didn't realise it was for the 1280 too. That's good to hear, it sounds ideal for my needs then as the slim DVD will be in a powered enclosure...



    Thanks Mike...

    The secondary 5v supply will be going to the powered USB hub.
    If you want, you can try splicing both the USB hub AND the firewire drive to this same output. It MAY handle the load.

    Well, technically it's not. It was designed for the P1900 since people needed the 3rd output when powering their +12V screen from the secondary output. However, it DOES fit inside the P1280 enclosure. But you'll have to clip off one of the jumper connectors and solder it to the +12V pin on J1. It was designed to plug into a jumper header on the P1900 to derive its +12V input. This is no big deal if you are comfortable soldering.

    I'd feel safer with a dedicated power line for the drive...

    My current temp setup is a laptop which I dismantled and soldered wires to the back of the power switch on the motherboard. So yea I'd be happy to solder it in with the instructions to do so....

    Mike, as the 1280 has been replaced by the 1290, does it still need soldering or is it plug in on the newer PSU ??

    You'll still need to do some minor surgery to install the P5V in the P1290. This will be the same for the P1280 & P1290.
