A:Answer The type and amount of memory is dependent upon the Motherboard you're using, rather than the PSU (Power Supply Unit). There's no memory requirement for a PSU, as it is basically only supplying power to your components.
You will need to reference the technical guide for your PC or Motherboard packaging (if it were purchased individually) to find out what type and capacity your PC can accept. The information will look similar to this; "Compatable Memory - 240pin DDR3 1333/1600/1866 (OC) - 32Gb maximum capacity."
