    The Radeon HD 5450 does not use a lot of power at all. At most it uses 13w of power and that would be when playing games. You should have no problems with a 240w PSU. Playing a Blu-ray movie uses 9w.

    jaguarskx - excellent, thanks.
    firo40 - the onboard 3100 isn't working correctly - causing display issues.
