Is 500 watt PSU enough for my desktop or do I need more?

I am building my new desktop and this is my first time.
I have selected:
Motherboard: Asus P8 H77-m pro
CPU: intel I5 3550 quard core
RAM: corsair vengeance 8gb (2*4gb) DDR3 1600
graphics card: 1gb
HDD: samsung F3 1 tb 7200 rpm
optical drive: dvd r/w- not selected any brand yet

Firstly, is this configuration okay? I mean, is there any nonsense mismatch?
Next, what capacity of PSU should I use? Does a psu come with case?
I would also like to know what brand of graphics card and optical drive are good and economical?

  1. You'll need to be more specific on the GPU. VRAM doesn't mean anything.

    Though as far as I know, 1GB VRAM are usually low-mid range cards so 500w should be fine.

    I would not use any PSU that comes free with a casing, they are known to be of really cheap quality most of the time and has a chance to fry your components when they fail.

    nVIDIA and AMD are the only brands worth getting for a discrete graphics card. Give us your budget though, it's hard to make a recommendation without one.

    CPU is good, but you're paying tens of dollars for a couple of 0.1GHz that you won't even notice in real life play. Get the i5-3450 or 3470, whichever you find cheaper.
  2. Thank you for your kind suggestions. In fact, I don't game much. But, I don't want to gather outdated versions too. Yeah, I think I'll buy I5-3470. It's price is same to the price of I5-3450.
    About graphics card, I want it within 70 dollars range. What would be better?
    I selected to buy corsair enthusiast 650 watt PSU.
  3. Graphics: EVGA GT -520 1GB 64 bit. is it okay. It is only around 50 dollars?
  4. This should be a fairly good upgrade from the GT 520.
    According to Tom's GPU hierarchy chart, it's 7 tiers above the GT 520.

    650w is too overkill for your system. Even a 450w unit would be enough.
    I suggest a 500w at most for you.
  5. Antec offers a great psu at a reasonable cost check these out you might like one

    This is a basic 500w non modular @ 49.99 free s/h from amazon

    This one is a 550w modular 80 plus model @ 54.99 from newegg free s/h

    Same gpu excella recommended prolly best card for the money at that budget.
