i am using the hdplex with cpu @176w max tdp. no issuses !
ps: I measured the power consumption at the wall socket with a multimeter, even running FurMark, CPU Burner, and even DiskMark. The maximum power draw was 268w at the wall socket, and that only lasted for a few seconds. No problems at all! The HDPlex 250W handles peak loads very well.
btw… Power consumption in idle mode has dropped from 20W to 15W! The HDPlex is also very efficient!
That say I have a simple MB (128Gb of RAM) with 1 ssd (4To Samsung 990Pro…) did not see more than 230W at the socket when max power (160W for a few sec..) (using sudo tuned-adm profile hpc-compute) (and it was with a old “80 PLUS Gold” …)
If you do not use other elements it may be good for the 250W DC-HDPLEX with max power…
