Please suggest me a decent PSU as per Watts consumptions.

Greetings ,
I've been in a huge confusion ever since i decided to buy a graphic card regarding which one i must go with and i finally found something good enough for me.
My PC spec is very weak and hence i only needed a gpu which would enable me to play games like Crysis 3 , BF3 , Heart of the Swarm etc at High [Not ultra or very high] on 1280x1024 resolutions. Hence , i chose Radeon HD 7770 , which was perfect for me considering my weak pc spec.

This is my PC spec:

Processor : Core2Duo E7400 @2.80 ghz
Mainboard : Gigabyte Tech G31M-S2C
RAM : 2x2 = 4 GB DDR2
Hard disks : 1 TB x 120 GB [2 HDD]
GPU : Radeon HD 7770
PSU : 250w [ NEED SUGGESTIONS FOR REPLACEMENT]
OS : Windows 7 32-bit

The real reason i posted this thread is because i would like you guys to give me a BRIEF watts consumption of each and every component i mentioned to you in here so that i can go for a good PSU as per it.

Would 500w be enough for me? or should i go for 600w? , my budget is minimum.

Thank you in advance.

  1. Agree use a PSU calculator. This is the one I like.

    EDIT: Without calculating it up, I know your PC will draw under 250 watts. Use the calculator so you can plug in other details like number of fans etc. I suspect when your done it will show just over 200 watts draw.
  2. There is no need to go too technical. A Cosair CX430 430 watt psu for $30 after $10 at Newegg will work well. Very little competitions at the lower end price point. Good quality and a good company to back it up' Check the reviews.
  3. I don't need the exact consumptions figure , any rare assumptions on each of those components is fine for me..
  4. even with a 7770 your gonna be at "low" settings at 720P rez. youre on the borderline to run todays games. and 4gb of ddr2? your 32bit windows only uses 3.4gb. and a core2duo3.0 is required for crysis3. you are at the bottom of the barrel and need an upgrade.....can you play it? sure at 20fps.

    The answer is they draw about 210 watts give or take. You asked it as a break down if you want that use the calculator and it will answer your question. The two main pieces listed below(rounded). A 400 watt PSU would be more than adequate for your build.

    Roughly:
    Core2Duo E7400 = 90W
    Radeon HD 7770 = 90W
