    Am about to assemble new system consisting of the following.

    2 Hitachi deskstars 2 x 160GB
    2 Samsung spinpoints 2 x 500GB
    Intel Q6600
    2 x 2GB 6400 memory modules
    FX5700U Graphics card
    Wifi card
    Lian case with 3 fans on board
    DVD writer
    CD drive

    Hoping to use same PSU from old system ie Silent X PSU@400W

    Is this sufficient?
    Plus I am going to be editing HD AVCHD video is this graphics card up to it?
    If not recommendations.

    Regards

    Re: Power supply size.

    Probably a good move to get a new PSU if that was isn't too fresh but as long as it's a pretty effecient 400W I don't see why it wouldn't work.

    Try this calculator http://extreme.outervision.com/PSUEngine

    I've just tried inputting your rig and it comes to 305W, so you should be fine. Quality (voltage regulation stability) is more important than quantity.

    The PSU calculator is complete nonsense, that system is under 200w so your current PSU is plenty.

    Your CPU will be more than capable for your editing, the GPU doesn't matter in this case.

    Your current PSU will do fine but if its an old PSU I'd upgrade it anyway since you are getting a new PC, when my PSU died it caused a permanent hardware problem.

    Rant Mode On

    Will people stop responding to these "will my 400W PSU (or whatever size) run this system" with "look at this PSU calculator... blah blah blah". It could be a 1 Gigawatt PSU and still be completely inadequate if the 12v rail only produced 1 amp without knowing what its complete specifications are the is no way for you to tell if it is adequate or not.

    However as a sweeping generalisation older power supplies (and cheaper newer ones) tend to have more of the Watts available on the 3.3 and 5v rails this means that the 12v rail can be underpowered which is bad.

    End of Rant

    To the OP,

    Look on the side of the PSU the should be a sticker with the specs for each rail (3.3v, 5v and 12v) if it has a single 12v then you should aim for it being at least 20A if you have multiple 12v rails then they will probably be around 15A each. If your PSU reaches these levels then you are probably going to be alright but I can not vouch for the quality of the PSU, not having read a review on one or owned one myself.

    Personally I would move to a new PSU it will likely have a higher efficiency which will save you money in electricity in the long run! And you will know that it will happily do what you want it to!

    That video card isn't PCI-E is it? How would that fit onto an IP35 which is PCI-E.

    Would have had to go in a standard PCI slot.
