Sorry in advance if this is not the right place to ask this question or if it has been ask already.

Question:

How do I determine what PSU size to get for my new rig.

Items to be included;

Processor= i7 K
Mobo = Asrock Z68 extrem 4 or Fatality Z68 (still doing review) but leaning towards Exrt 4 due to budget.
SLi = GTX 460 x 2
Water cooling = yes (first time trying this)
- CPU block
- GPU block x 2

is a 500W suficient ? I don't want to over power it or worst under power.

Newbi here. So please share your wisdom.

PSU brand and model (perferably BLACK) as I am going for a full black concept.

Thank you in advance for your wisdom.

Thanks guys.
