I was looking at
http://www.ebuyer.com/UK/product/114941however evga are not very specific,
i.e. they ask for 26amps on 12v psu, and as their site is aimed at the end user whether in/competant one would assume they mean 26amps on a single rail, because most end users will not know that a psu can have multiple rails/ and there is no mention of this on their site
