    Hi I have an HTPC system with the following specs:

    Mobo: Asus P5E-VM DO
    CPU: E2180 @ 2.8GHz @1.3v under load
    HDDs: A raptor 74GB and a 250GB Seagate one
    My case also drives a 80mm and 120mm fans
    I have no DVD/RW (it's external), and that's it.

    My PSU has the following specs:
    Output Maximum Load
    +12V1 18A
    +12V2 18A
    +5V 20A
    +3.3 20A

    1. Maximum continuous total DC output power should not exceed 350 W.
    2. Maximum continuous combined load on +3.3 VDC and +5 VDC outputs should not exceed 110 W/28A.
    3. Maximum continuous combined load on +12V1DC&+12V2DC outputs should not exceed 300W/25A.
    4. Maximum peak total DC output power should not exceed 385 W.

    Considering how modest my system is and how efficient (for 350W) my PSU is, wouldn't it be possible to add a 9600GT (@stock)? I'm asking this because nvidia requires a 400W PSU as minimum, but considering that my +12V rails combined produce 25A, wouldn't it be enough juice for my (slightly) o/c'd CPU and GPU combined?

    Thanks in advance...

    From what I have read, the 9600GT draws over 200watts under load? So the math of it would tell me no, 350W would not be enough. But to remember PSU's are always under rated anyways so....

    According to http://www.extreme.outervision.com/psucalculatorlite.jsp , my system WITH the 9600GT added would draw 266W under load and 295W under peak load (everything 100% utilized). Of course I'm note even sure how accurate their PSU calculator is, so...

    Seems about correct, bearing in mind you have a highly overclocked cpu and a mobo that has a power-hungry chipset.

    @TS: It'll definitely work. Full load consumption for your rig with the 9600 would be around 200-220W.

    You're fine but your PSU should be a good brand not a no-name.

    It's the following http://tinyurl.com/59448f , only the 350w variant which is being used with the Minuet HTPC case. Antec seems to very proud for them, I don't know if they right to be so, though...

    OK, I guess this or this should convince you that it's OK. :)

    Oh great, that would probably leave me space even to overclock the GPU. That would result to a great HTPC gaming machine, thanks for the info.
