Hey folks,
currently mining at 170Mh/s with 6*rx 470 4GB (MSI Gaming X), that's roughly 28.3Mh/s per card with 870W measured from the wall (total power consumption).
We can go a bit higher in terms of hashrate but we only have a 1000W Power Supply and we don't want to take any risks.
In terms of clocks and wattage, our cards are at 1100Mhz and 1050mV for the core and 2050Mhz and 1000mV for the memory.
Few questions:
1. Is it safe to draw ~870W from the wall, 24/7 with a 1000W PSU (Aerocool Gold+)
2. ~170Mh/s for 870W, is it a good ratio or do we have room to optimize the hashrate (without impacting the electricity consumption) ?
1. First of all. 1000W PSU meens that it can support 1000W output load , if its gold+ i think you current load is 870*0.95=~820 Watt of 1000 W PSU ability - No problem
2. Im using a lot of 4 Gb 470x cards, and usualy drive them in 1120/900 2000-2100/900 from 28 to 31 Mhs ( depends on vendor). On my mesurement one card eats 110-120 Watt itself.
