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.
It is better to make farm with a reserve power supply for future algorithms, which can be more demanding. This is usually done so, it is considered necessary power of consumers and mount a 20% of the stock. 6 cards x 150 = 900 + 100 (system)=1000 + 20%= 1200W will be good.
Ok, going for EVGA G2 1300W to be safe. Should set my mind to rest.
