    Just like above, I bought a zm600-HP today along with cm690 ii advanced case.
    Installed everything, now when I turn-on the pc, all the fans twiches but after that nothing happens. I'm pretty sure its not the Psu nor would it he the Mobo tho...

    What could be the problem???

    it now runs with out power to drive but when I install a new clean hdd it runs but pc can't find it the hdd

    I doubt its the Psu, cause I use SATA power cable to power the dvd Rom and its able to work and recognizes it yet it doesn't recognize the hdd? How weird is that? And there is no ways that the Psu is too weak, since my last Psu was only 350w and it runs nicely

    It's a SATA and BIOS can't find it...but I felt the hdd, doesn't feel like its spinning...but the BIOS can see the SATA dvd Rom but not hdd...not sure if its the Psu tho, a faulty one maybe?

    My spec
    Biostar I45 Mobo
    HD4850 1GB
    2gb RAM
    Q9400 cpu
    ZM600-HP

    Don't think ill draw that much power

    It's a modular Psu, and yes swopped both cables and both work on dvd Rom and not hd...I've tried all cables
    Could it really be the hd?

    Ok when ever I plug the hd with OS on, it doesn't start, the power and lights flickers then stops...but if I take the hd off the pc runs???

    Yeah I know it doesn't boot, that's why o was hoping to reinstall Windows cause I think the old one is dead...
    and all my components are the same I just got a new Psu and case...so I don't know why it does work?

    check in the bios or user\motherboard manual about changing the settings for the sata to maybe compatibility mode or enhanced mode.

    Hmm...I have tried both mode in the BIOS for the sata settings...still not want work, but like I've said before, its able to see my dvd drive, which is also sata and the flat power cable...so I think it could be the hd problem?
