I have a rig with 4 AMD 550 Gpus, had a Thermaltake Toughpower 1500W , I was told the brand might of been the problem.
Getting a 1200W PS to replace it.
I can't get the specs on the Wattage for the GPUs, I've seen 200w per AMD 580. Anyone know about that?
Anyone run 4 GPUS with a 1200W Power Supply? Or even 5?
Thanks.
I think you should be pretty ok with your 1500W psu, and even if you change it to 1200W there won't 'be a probelm
but why do you want to do that? do you have some problems with power on your rig?
look, properly tuned rx480/rx580 with low voltage sucks from PSU about 115-125W only, so 4 of them will draw 500W only!
hell, rx 550 chip consumes even less then that, I guess less then a 100 watt!!! you do have plenty of power to build the rig of 6 such cards!
