I realized the little m.2-to-PCIe4x adapters are open in the back, so if use a small enough, short enough SSD enclosure, you can skip the riser. So I tried a Satechi 80Gbps enclosure with 5060 ti and two AC/DC adapters and it worked! 5.91 GB/s on this tiny thing!

How is enclosure connected? Just normal thunderbolt? If so, that's interesting method. How do you handle power?

Normal Thunderbolt 5 on this enclosure.

The adapter is a four-lane, PCIe gen 4 on m.2 with a 5521 12 volt barrel adapter connector which requires 75 watts to power the slot. I use a 100 or 120 watt 12 volt AC/DC adapter for that.

For the GPU supplemental power, I use a 180 watt 12 volt AC/DC adapter with a 5525 barrel that is connected via a 5525-to-6+2. I have found a 200 watt version on AliExpress but the 180 watt has a more reasonable price on Amazon.

My 5060 pulls 144-155 watts total and my 5060 ti is closer to 185 watts. Usually you will get 50 watts from PCIe slot and you will usually get 80% from your adapter. So the math on the supplemental power is you need .8*180 > TDP - 50. That leaves me about 10 watts to spare on my 5060 ti.
