Intel SSD Not Recognized rockpi4b

Trying to use Intel 670p SSD (#SSDPEKNU010TZX1) and getting nowhere. Not recognized in debian or ubuntu (current versions downloaded from radxa site yesterday). I had originally tried this with the M2.HAT, but backed up to inserting directly into the rockpi - with identical results. No nvme device visible.
This is a new out-of-the-box SSD.

If I compare booting with and without the SSD, I do see a difference in the journal entries. In both cases, the entries contain failed related to 3v3, 1v8 and 0v9 supplies. Without the SSD present, the entries conclude with

Apr 19 10:59:59 barn-pxe kernel: rockchip-pcie: probe of f8000000.pcie failed with error -110

With the SSD present, the entries conclude with

Is this a power supply problem, or something else?
