Can someone tell me the Max power draw for a stock Rx 480 4GB? Trying to figure out a PSU for a 6 x 480 rig.
Use nominal values from datasheet for this purpose (=150 W) and add proper headroom for overclock, spikes and working point at good efficiency.
So a gold rated 1200W PSU for 6 x 480 + MB with Celeron-CPU and risers/SATA should be just fine in other words. Even without undervolting.
