  1. Hi .. What is your exactly type your cm 500W, extreme power plus or silent pro from CM ?
    PSU important for safely when OC GPU and CPU !
    Just suggestion for safe longtime your hardware. Actually I don't like OC GPU, it can decrease life time GPU for fast.

    Hello Again!!!
    ya, its 500watt extreme power plus
    My gpu memory clock rate is 1200mhz
    and Core clock is 850mhz
    so
    i want to increase default clocking speed to 50mhz
  3. you can overclock both, just keep testing them for stability as I wouldn't worry so much about power,, the CPU you have will far outstrip the power increase required from the GPU as the 5770 is not a power hungry card...
  4. I'm sorry for this time, I does not recommend overclock GPU for safely all hardware. Your psu poor efficiensi arround 72-77%, and real crap 460 labelled 500W.

    I think this time if youwant oc gpu for safely, you need good PSU from brand like antec,corsair, xfx, ocz,
    Not more than a year, first damage HDD , VGA , motherboard . Just suggestion

    I calculate power of all hardware in my pc that is maximum usage 324watt
    on this site
    http://www.extreme.outervision.com/PSUEngine

    hardware is
    Amd phenom ii x6 1055t
    Ati 5770 1gb
    1 lg super multi rom
    1 sata hdd 7200rpm
    Asus M4a78lt-m mobo
    2 88mn fan
    4gb kingston ddr3
  6. You'll be fine, just don't try anything to crazy, that power supply isn't the best, but it can power your system fine.

    So can i overclock my gpu as well as cpu
    i want increase only 50mhz
  8. you'll be fine,, you aren't doing "extreme"
  9. Don't .. They don't know power consumption overclock cpu 1055T at 3.5ghz + oc hd 5770. PSU engine your link calculate at default not overclock ..
    I know it because I have 1055T . Just suggestion good luck man.

    m confusing
    some saying fine and some warning
  11. He has a HD 6770, and the PSU has 30A on it, a CX430 can easily power a HD 6850, and that has 28A on it, a HD 6770 uses quite a bit less power than a HD 6850, his PSU will be fine as long as he doesn't push the voltages too high.
  12. ya,, you don't need much more than 400 watts unless you have really high end card (it will require connections you won't find on a 400 watt PS anyways) or multiple cards - which a 400 watt PS won't have enough connections for.
