I making a build which I will buy in late June or early July and I need advice on a power supply to power it. It will be used mostly for playing Guild Wars 2 and surfing the web. This is going to be my first build, so I think a modular PSU would be best, but feel free to disagree and give advice on that matter. So this is my build: http://pcpartpicker.com/p/8b6p

Notice I have a 750W PSU there. Is that overkill for this build, and I should just go with a 600-650W PSU, or does 750W seem OK? Also, if there is a better PSU out there, instead of the Enermax one, please feel free to leave suggestions.

i5-2500k gives comparable performance but overclocks better. I don't honestly think the difference is much. The new Ivy Bridge CPUs tend to be 10-15% better at identical speeds, but give 10-15% less overclocking room because they don't dissipate heat as well. So pretty much a wash IMO.

Switching to the 2500k won't make it use less power. It actually uses more than the 3570k. As others have suggested, you'll have more than enough room in the 500W-600W range with either processor. Hell of a deal on the Corsair Builder Series 600W right now. Arrr.

Your whole build is an overkill to play guild wars 2 and surfing the web but I like it. I would do a small change tho: get a i5 2500k and a PSU from Corsair or Antec. 650 or 700watts should be enough from either brand.
The best thing about modular PSU is the easy cable management but even a regular PSU is easy to manage with some time and patience
 
An HD7850 requires a 500W PSU with one 75w 6-pin PCIe power connector and 28A on the 12V rails; amps on the 12 V rail is more important than watts.

The Rosewill Capstone 450W is actually more than sufficient for your build and is 80+ Gold certified: http://www.newegg.com/Product/Product.aspx?Item=N82E16817182066

Other options:
1. OCZ ModXstream 500W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817341016
2. Antec BP550: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016
3. PC P&C MKIII 500W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817703035

Why do you recommend a 2500k? And if I don't switch to a 2500k, would 650W be good for my build, or would 750W be better?

Alright, so I'll be getting a 600W-650W processor for my build. I'm currently looking at the OCZ ModXStream Pro 600W Modular PSU from Newegg.com. Do you think this is a good PSU, or should I just go with the nonmodular Corsair Builder Series 600W?
