Hi guys, I just got a call by my mining partner. We are running 6 of the following sertup in a warehouse atm:

- asus z270 prime
- celeron g3900
- 4gb ddr4 ram
- 8x sapphire nitros rx580
- hp dps1200 server psu
- 160w pico psu

he just installed new wires for power to place the miners at a different spot in his warehouse. now he is telling me that on the new place when the miners are just started up, the power consumption is about 3.5A at 230V wich should be around 800W. After 20 minutes, this climbs to 4,8A or 1100W. I told him this is very unlikely but he claims that he has professional measurement equipment which should be ok.

I only can check the gpu power consumption per software by remote which is around 85W per card and doesnt change. all fans are running at 100% so when miner gets warm that shouldnt make such a big difference. The only thing I could imagine is that these server power supplies with breakout board are pulling close to their 1200w max after some time regardless if the system needs it or not.

what is happening here please?



It seems its a normal consumption depending on the algo you are mining

for eth, default RX580 would go around 200watts per card

not unless you do modding and underclocking

which I bet you already did

Power consumption per software is different compared to power draw at the wall
