I always buy seasonic this days in my country finding this pus hard I read a great reviews about this bitfenix Whisper M 650W any one try this I will run 4 Rx 560 mining eth
You can yes. But you would have to make sure it is undervolted before you start mining.
RX560 if it is the same as RX580 is about 130W without overlocked and undervolting when mining.
so 130W x 4 GPUS = 520W which is 80% of the total power in the PSU.
However as it is Gold 80% efficient then that would mean it is technically at its maximum power give without any errors and that hasn't even powered the MOBO or HDD/SDD or RAM. (650W x 0.8 = 520W)
So If you do use it, make sure you undervolt first.
If not, then get a PSU with higher W's.
Cheers.
Great advice, I was just about to chime in until I noticed the red text showing you posted.
Anything above Gold rating is good in my honest opinion so this should work fine - also keep in mind that the MOBO / CPU and risers will be powered too, remember to add that to your calculation.
560's are significantly less at power draw then 580s but I totally agree that you should undervolt to maximize profits.
(I think its around 80w compared to the 130w 580s have)
