    How do you know your rectifier is bad? Can you read any markings on it?

    The current rating is crucial. It's likely rated to double your line voltage or so, but you need to replace it with one with the same or higher current rating. Look around for other components it might have taken down with it.

    i have replaced the capacitors it did work for few minutes but it died again thats why i want to replace capacitors and voltage rectifiers thers also a diode sb360 thats giving 0.2 on multimeter other forums syays diode should be 0.5 is that correct and the voltage rectifier will 1000v or 750v be ok for ps3 psu thanks

    According to the datasheet 0.2 is correct for a diode current <0.1A. At 3.0A the diode would drop 0.74V.
    If in doubt about a component property, always consult its datasheet.

    That bridge is rated 6A and 800V. Replace it with a bridge rated at least that high on both measures, if you're convinced it's bad.

    Hi just one last thing i have auto raging digital meter the diode sb360 give exact reading of 0.160 is that too low.

    No, the apparent voltage drop depends on current and your meter is supplying very little. The low number might be suspicious but it doesn't tell you anything for certain.
