My miner is runnig for a few days and today i checkt the power consumption with a special device. The consumption is around 575 Watts.
I had assumed that it will be around 300 Watts.
Why is the consumption this high and how kan i fix it ?
Rig:
2x MSI Radeon RX 470 8G
Intel Core i5 4460
Gigabyte GA-Z97P-D3
4GB Corsair 1600 MHz
Corsair 60 GB SSD
Corsair RM750x Gold

Mining arround 42 MH/s.
How can help me?
Update:
I orderd a third card from another supplier. It's from a diffrent batch as well.
I swapped al the cards tried them single, double and with three of them.
It doesn't matter or i swap the card from different batches i get the same power consumption every time.
Minig with only 1 card: 305 Watt.
Minig with 2 cards: 570 Watt
Minig with 3 cards: 819 Watt.
This doesn't seem right

Benchmarks gives around 157 to 163w for this model. So you probably are in the high value due to the fact that mining is a heavy work. So 326w or a bit more for your cards. The rest of your system use 249w, this is a bit high too but it depends of a lot of things. Higher temperature due to mining can elevate the consumption but i admit you are almost twice the value on the rest of the pc. Try removing each graphic card and calculate the consumption of the pc without this load, then add card one after the other an mine and see if one have an abnormal consumption. Hard to say more...
