hi, im in the process of building my 6 x sapphire r9 280x vapor-x rig
currently i have 2 x corsair ax 860w psu's so 1720w total using an add2psu connector do you think 1720w will be enough to power these cards, ive heard they are about 250w each when undervolted so gpu's will total 1500w
so that leaves 220w to run cpu (55w) + ram + mobo, i wont have a hard drive as i will be running from usb stick and no fans apart from cpu cooler
i also need to find out which cards should be connected to each psu, each card requires 2 x 8 pin connectors
should i run the motherboard 24pin and 2 cards from one psu and 4 cards from the other psu or should i run 3 cards from each psu or should i use 1x8 pin from each psu on each card?
i dont have powered risers, can i solder a molex connector to my un powered ones? or will the motherboard be able to handle the power of 6 gpu's?
any help would be much appreciated, im just trying to figure out possible problems before hand so i can piece the thing together fairly swiftly when the rest of the bits arrive
