Which power supply should I get?

Hello everyone,

I'm planning to build an affordable gaming computer for the first time and I just wanted to know how much watts (power supply) I need to support my computer.

Here are the computer components that I am planning to buy:

Motherboard- http://www.newegg.com/Product/Product.aspx?Item=N82E16813131623R
Video Card- http://www.newegg.com/Product/Product.aspx?Item=N82E16814125327
CPU- http://www.newegg.com/Product/Product.aspx?Item=N82E16819115222
Memory- http://www.newegg.com/Product/Product.aspx?Item=N82E16820145218
HDD- http://www.newegg.com/Product/Product.aspx?Item=N82E16822148597
Optical Drive- http://www.newegg.com/Product/Product.aspx?Item=N82E16827106289

I'm planning to buy a 500 W ATX power supply and I was wondering if this is too much or not enough power. Also will a ATX power supply fit in a micro ATX tower?

Here are the links for the micro ATX tower and the ATX power supply:

More about which power supply
  1. ATX PSU will fit in a micro-ATX case.

    The NewEgg fine print on open box items should concern you if you're getting a open-item motherboard:
    Open Box Refund Only Return Policy
    "If you purchase an Open-Box product Newegg guarantees only that you will receive the product itself; accessories MAY OR MAY NOT BE INCLUDED with Open-Box products. Newegg will not send you a missing accessory, even if the missing accessory is required in order to properly make use of all the product’s advertised functions."
  2. Best answer
    Corsair 400CX $30 after $20 rebate a bit less power but much better overall quality and after rebate less expensive. 3yr warranty vs 1yr for the Rosewill.
    Most important it has enough power for all your parts and is a well reviewed and respected PSU.
  3. Hmm... I never knew that. Well thank you for the short reply and the warning. So I definitely should get a brand new motherboard then right?

    good quality recommendation for the price.
    Corsair and the open box advice.

  6. Im looking to see if I can find a NewEgg combo deal near the same price with a unopened box motherboard.
  7. Core i3 530 & ASUS P7H55-M PRO $180 after $30 discount is about $4 less than your original CPU/MB pair.
  8. Combo deal: Corsair 400CX and the DVD burner you picked $61 after $7 discount and before $20 rebate on PSU.

    Thank You WR2. You've done more than enough of what I expected. Also thank you for the great suggestions. I definitely will consider of taking your suggestions.
  10. You're welcome.
    Just in case we've saved enough to upgrade the HDD a bit: Seagate Barracuda 7200.12 $39
  11. This is interesting. A Cooler Master case: COOLER MASTER ELITE 335 $40 after rebate free shipping and $10 off promo code EMCYVNY48, ends 7/26.
    Thats $30 a/r and free shipping. Vs $30 and $10 shipping for the other case.
