I want to ask knowleded people about power supply for the mining rig. I have a 6 VGAs RX 580. CPU G3900, 4GB RAM, SSD, Mainboard and 2 PSU SAMA Armor 750W. I want to distribute the load of PSUs as follows:
PSU 1 (3 VGA (185W each) + 2 riser (15W each) + CPU (51W) - CPU power supply) = 555w + 30W + 51W = 636W
PSU 2 (3 VGA (185W each) + 4 riser (15W each) + Mainboard (RAM) + SSD = 555W + 60W + ~10W SSD and mainboard = 625W
But when I consulted my younger brother who had installed this mining rig, he insisted on delivering the following:
PSU 1 (2 VGA) + 4 riser + CPU + Mainboard + SSD
PSU 2 (4 VGA) + 2 riser.
I try to calculate and I saw that one PSU 750W that loads 4 RX 580 + riser (185W), it is not good. But his brother did not explain, he just said he plugged 3/3 instead of 4/2 as he told me, my mining rig will dead faster. I was too fussy to look up here to consult your brother to see how to distribute the power supply. Thank you for your help.
