Highlighted rows differ between these boards. “Not stated” means the Amazon listing does not mention it: the board may still have it, so check the maker’s specification. Power phases are printed as stated by the maker and are not comparable between brands. Prices are the new price on Amazon.co.uk at the time shown; the price on Amazon when you buy is the one that applies.
