Can PCIE X16 Gen4 SlimSAS 8i x2 Adapters be powered by a second PSU ? or does it need the same PSU that powers the motherboard ?

Can [PCIE X16 Gen4 SlimSAS 8i x2 Adapters](https://i.ebayimg.com/images/g/HTUAAOSwYUpj6fpw/s-l400.png) be powered by a second PSU ? or does it need the same PSU that powers the motherboard ? since the PCIe slot already provides 75 W from the first PSU, I’m hesitant to power it from another PSU for fear of a blow-up.
