@deeveedee, this could be something to try out:
It appears that at least on the lenovos, people are reporting that getting a higher wattage power supply unleashes more CPU performance. Especially on the i7-i9. My 65W G5 came with a 90W Power supply but our CPUs have a PL2 of 135W. I don't know how HP handles these. HP parts research seem indicate that HP uses the same Motherboard and cooling for the 65W and 95W CPUs so the major difference would be the 150W power supply. the 95W i9 has a PL2 of 235W... Which I don't think these machine can sustain. I ordered a 150W power supply to see if it could help the multi thread performance of the i9 9900. In comparison, Lenovo uses 135W/170W/230W power supplies Vs the puny 90W from HP for 65W TDP CPUs. Even the 35W i9 9900T appears to benefit from getting 135W Vs. 65W on the lenovos. Some info here.
