hi
i would like to overclock my r9 290x so which psu do u recommend
Corsair cx 750m or EVGA 650W GQ 80 Plus Gold (which one is better)
thanks
ps if i want to use crossfire can i use one of the above mentioned power supplys?
For a single R9 290x the EVGA is the (much) better choice, but for xfire neither will do. For xfire you will have to look into at least a 850 watts PSU or higher.
