Hi all My first post. I have just ordered my new internals for a gaming PC i am builing. i have built office Pc's before and have just used 450W PSU's but this is my first Gaming PC. I have put a list of the components i am going to be using but am unsure as what size PSU to use. I was thinking of a Corsair TX750w, but i have heard that if the PSU isn't large enough it tends to fry things. I have read the Graphics card and CPU cooler i am planning on using are large power users. My PC spec was inspired by the DEC issue of Custom PC AMD article. I do love AMD but once the sandy bridge came out they seem to of fell behind until recently. anyway here is the list, would a 750w be good enough all advice and opinions welcome.

I've just gone through this, try using the Thermaltake PSU calculator to get the size of PSU you will need.
Be Quiet Pure Power 630W I have it, it is well built German Engineering, quite, solid and modular. http://www.ebuyer.com/283836-be-qui...u-bn182?utm_source=google&utm_medium=products My rig is also v.similar to yours
i have a TX850 thats got more than enough for that rig and future up grades and is dead silent so i can recomend that!
550W will suffice from what I can see. 750 is more than enough. The Be Quiet mentioned above is a great choice.
550W is plenty as others have said. If you're planning to get a second card for CrossFire, you might want a 650-750W though.
