Is 550W enough?

Hello,
Is 550W PSU enough for over clocking CPU a little with water cooling and also fairly high end GPU such as HD Radeon 7770?

More about 550w enough
  1. Edit: Was looking at OCZ-ZS550W-UK 550W ZS Series 550W.
  2. easily.. the OCZ will be fine as long as no second card...
  3. Yes, more than enough, and the 7770 isn't a high end gpu, it's a low end gpu.
    It will do even for two 7770 CF.
  4. Hi. The HD 7770 isn't really considered high end but a quality 550W PSU is more than enough for it. If you're from the UK, get the XFX ProSeries 450W here: http://uk.pcpartpicker.com/part/xfx-power-supply-p1450sx2b9
  5. Is XFX a good brand?
  6. It is, it's made by seasonic, it's of high quality.
  7. quick question, would it fit in xigmatek midgard ii? (i will research more later)
  8. Yes, it fits, there's also the 550w version if you want to add a mid/high end card(with two pcie connectors).

    If you don't, just get the 450W, is more than enough for it, with plenty of room to spare.

    This is $50 with MIR and occasionally goes for $40 if you're really patient and it's 600 watts.
