Re: Radeon released RX 480. (Card is Released)

For the 1000W output power supply, it can output 1000 W, while it can draw 1000W/91% 1098W. So it still has some redundency.

I thought that efficiency is related with the difference between the load needs and the power that you need from the wall.

For example, if you have a load that needs 100W, and you have a PSU with an efficiency of 90%, then you get from the wall 110W.

The efficiency is highest at around 50% of the maximum output. It is lower when the output is too high. I run my output around 70-80% of the maximum output.

My electricity price is high. So I use the platinum power supply and also a big specication PSU, so that the efficiency is high.

The difficulty of the Ethereum is rising fast, in the next 3 months, unless you have the 470 or better GPU, you will not make much profit in the Ethereum mining.

yeah you will need current gen cards, 14-16 nm to be able to profit, although the nanos are quite efficent as well i have a bunch of those undervolted nicely
