    Default using a 1u server psu for a desktop

    Hello everyone,

    Right now I am building a custom case and i looking for the narrowest psu possible. I am currently eying the SS-520H1U by seasonic. Unfortunately it only comes with 3 molex adapters, an 8-pin mobo power connector, and a 24pin connector. It has 40A over 3 12V rails and supports a total of 520W. I wanted to use this to power the following system:

    Q9550S
    ASUS Maximus II GENE P45
    2 x 2GB DDR2-800 @ 2.1V
    ATI 5850
    OCZ Vertex
    Sony 5600-SH Slot load blu ray

    Does anyone for see any issues using this PSU? Will it work?

    Thanks

    40A on the +12V rails (probably actually a single rail) is plenty for that system.

    I don't think you'd want that, really, you don't!

    I'd give you about 10 seconds before you pull the plug...

    Thanks for all the comments, what other options do I have?

    The most powerful TFX PSU I can find is 300W and 21A over the 12V rails (says it has 2 rails). It is the one made by seasonic. Is that going to be powerful enough to power a 5850 with the below configuration? Would it be enough for a 5770 and the below config?

    Also I have changed the system to this:

    i5 750
    Gigabyte MATX P55-UD2
    2 x 2GB G.skill DDR3-1600 7-7-7-20 @ 1.65V
    OCZ Vertex 250GB SSD
    Sony 5600-sh slot load blu ray drive
    2 x 120mm Noctua Case fans

    Thanks everyone, your help is very appreciated

    What if i disabled the fans on the PSU, took off the top cover and then mounted some quiet fans on top?

    Without OC'ing, the above with a 5850 will be fine on +12V@40A.
    Yes. One of the last commincations I had with Dave Hammock before he disappeared from the web was how a major brand single +12V rail PSU wasn't shutting down when shorted. We were literally arc welding with the PSU. Hopefully Dave's absense isn't due to the fact that he got over zealous with the welding.

    It's pretty close.

    If you've got some time I may be testing it with my 350W Antec (Seasonic Made) TFX PSU.

    Cool, but what about this:

    300W @ 21A Seasonic TFX and the ATI 5770 with that system?
