    What size PSU do I need

    Probably asked a thousand times... But there's the 1001th

    - Via Epia MII 12000 or M10000 depending if I use my pcmcia wifi and cf cardreader for digicam
    - 512MB single DIMM 266MHz
    - W.D. 200GB 7200rpm 8MB buffer HDD (probably a big power draw)
    - Panasonic slot CD-RW/DVD
    - WiFi either my pcmcia card (will probably work only in my garage) or a USB device with antenna (better reception)
    - Royaltek Sapphire GPS (USB)
    - Lilliput screen (USB for touch screen but own power)
    - Wireless keyboard - Not choosen yet (USB probably)

    I might eventually get a good sound card in order to send separate RCA feeds to front, rear and subs amps (5 channels), so I need to consider having power for that card if needed. Or maybe I can send the digital output from the via SPDIF to a module that will separate all signals to send to the amps.

    Also, I read here that the resolution is not widescreen compatible on the epia so a pci video card might be wanted, I need to consider this also (not finished my reading on the subject yet, too much info on this forum;-)

    I think that's all I need powered.

    Will a Opus 90W be enough, do I need the 150W? What about the Audioforge 200W which sells for half the price (100$) of the Opus and has ITPS included?

    An OPUS 90 watt should be enough, but I can't garuntee it. If you have the possibility of putting the DVD drive on its own power supply if it is too much then I would get the 90 watt and take off the DVD if it won't boot, otherwise just spend the bit extra and get the 150.

    I'm running an AMD 2000+ with 7200 rpm hard drive, 3D card and a bunch of USB stuff and I'm drawing just a hair over 90 watts when I running at full processor usage. Developer (I am Chuck)

    The OPUS 90 watt would work will with your setup.
