As I said, the Hiper is the best value for money part I have seen in the UK. Save up for that. The Enermax will run it, but it will be too close for my comfort, and will be a waste of money if you upgrade, as you will need a new PSU. http://www.overclockers.co.uk/acatalog/Hiper.html
I did a price check, and it is £60 here. (I've ordered at half 4 from here and recieved it the next morning still. http://www.gladiatorcomputers.com/Pr...=SearchResults
edit: The Hiper has some patented design, which is apparently the same as what is used in aviation, but myself, I see it more in sound studios.
My voltages are fine. 12.032, 5.053 and 3.328.
