Trying to switch to server power supply onlu mining. Without second ATX. I have hp server supply and breakout board with cables. The risers are 6 pin ver 006c, which should be powered directly from the hp server power supply. But in this setup no picture on the screen. No signal is send from gpu to monitor. I try only with one first gpu card. Riser red LED is on when HP PSU is on. Processor fan is on also. I have Pico /160W/ also. Can't figure out why gpu do not turn on fans. I tried with other riser and other gpu. It was working fine with corsair ATX PSU. I`m sure it is possible, because at this video how they use only server psu for 6 gpu. I see from the video they use Pico for the main board.
