Can you run a 350 watt build on a 480 watt power supply?

Hi, I will be build my computer sometime soon, however I am not sure on this. If anyone could be of assistance, I would greatly appreciate it! I need to know if I can run a 350 watt build on a 480 watt power supply? Will it make any difference in performance, or is there any risks? I have posted a link to my build list below, please take a look if needed.

Thank you in advance,
Daniel D.

  1. It is recomended to have a larger power supply then what your build requires so it will run without any trouble!
  2. By the way, where is your build? No link posted below.

    if you may want more gpu in future the 550W XFX is a great psu. Wattage is not the only factor when looking at psus - current on the 12V rail is very important. The XFX supplies are good quality and are very quiet - highly recommend them.

  5. What is this build for? If it is for gaming, it is underpowered. I suggest this.

    I would spend less on the monitor and get a 7850.

    Do you have a link?
  9. I will be using this build for work, home-use, and gaming.
  10. Nobody told him the psu he has only can deliver 16A on the +12 rail ? That's actually less than 200W, the cpu itself is 125W(will also be fed on the +12v rail), the card will be ~100W(7850), even with the 550 ti, you'll probably will reach more than 192W in load with cpu+gpu, that psu is junk, most junk psus will damage the components when overloaded.
    I recommend getting a decent psu, an throw away the one that came with the case, never cheap out on the psu.
    Actually you just need a 400W psu for the 550 ti, but a decent one.
    You can find cheap decent psus like the Corsair CX430, Antec VP-450, Antec Neo Eco 400C, XFX 450 Core Edition, Seasonic 430W, Roswill Green 530W.
    Then look for a cheap monitor in neweeg, there's some for less or about 100$.
    For a Card either the 650 ti or 7850 if possible.
    Same price as your monitor and card, with new psu, gpu and monitor : http://pcpartpicker.com/p/IDSX
