I'm new to mining I need help with setting up GPUs with 750 watt power supply, I have two rx5700 and two gtx1660 6gb can I power these cards safely with the power supply?
If your PSU brand is Corsair or Evga you can safely go with 750 watt power supply.I have one Rx 5700 xt as you can see in the picture below it is doing 115 watt power consumption and it is the same at the wall because I have measured it with a Watt meter.So to do the math, 2 x Rx 5700 at 115 watt each makes 230 watt, 2 x Gtx 1660 at 70 watt is what I have seen but I am taking it as 90 watt it is 180 watt for both of them.Up until now we are at 410 watt plus 100-110 watt the motherboard you are at max at 510 watt consumption which leaves pretty ample space for the PSU,you can run your rig with a Corsair for years without problems.
However if you want to be sure use a 850 watt PSU and surely your cards are not overkill,but if you don't have the money by all means go with the 750 watt one as it will just do the job for your setup.
