Hi there! I just picked up a second hand PowerColour 6870 for my mac pro 4.1. (thought it was time to upgrade the GT 120!) I know i need 2 power cables and found a link on here to OWC: http://eshop.macsales.com/item/Apple/9227128/ I'd prefer to get them sooner so started looking around online but can't find any anywhere. I can only find male to female extensions. Does anyone know where to find them in the UK?
