questions about my new build plz

[atomos]

hi all,

Been looking into my new build and was looking at these parts..

Asus GeForce GTX 560Ti £169.99
Intel Core i5-2500K 3.30GHz £161.99
Asus P8Z68-V GEN3 Intel Z68 (Socket 1155) £144.98
Corsair Hydro H100 Extreme Performance Liquid CPU Cooler £99.98
Corsair Carbide 500R Midi Tower Case - Black £92.99
Corsair Vengeance Blue 8GB (2x4GB) DDR3 PC3-12800C9 £40.79

I already have 2x500GB HDDS and a Hiper modular Type-R 580W PSU. I will be overclocking and use PC mainly for gaming.

Questions I have..

1. Is the H100 gonna be over kill should I get a cheaper one like H60?
2. Will my current PSU be able to power all of this? (will be adding couple of colour fans to case prob too).
3. Any other tweaks ppl would suggest?

thx all

Perhaps it's time for a new PSU:

The 'Hiper-Explosive' Club

Have you considered the Thermalright Silver Arrow CPU cooler if it will fit in your case?

Had the PSU for good couple of years now never a problem with it. Just need to know if what I have will power what im after or not as Im at limit of my budget.

As for the thermallight cooler i was thinking a watercooling unit as be quieter. T'is a very nice cooler though, would be what I would conside if not the watercooling module
