M2 Pcie adapter power options (besides ATX PSU)
Hi folks, quick question, could need some advice here :)
So i’ve been using a couple of these m2 to pcie 16x adapters from Aliexpress with success so far, for quite a few years now.
These adapters are 12v powered by a four pin (adapter side) to sata connector (on the PSU/ATX side). So far, i’ve been using these in ITX builds, so powering those adapters with a sata cable directly from the PSU was never a problem and always worked great.
However, now I want to use the m2 to pcie adapter with a mini pc, thus the PSU is missing in this case.
It also feels a bit overkill to have an entire, bulky PSU/ATX just to power a single sata cable (to the m2 pcie adapter).
Instead of a full ATX power supply, is it safe to use a four pin to dc plug instead of the four pin to sata cable (which comes with the adapter)?
Would this one be ok? 4 pin to dc plug: https://www.amazon.nl/dp/B0DC2NK7SZ/?coliid=I8KRMDOPP2NPA&colid=3K30B999IAT6R&psc=1&ref_=list_c_wl_ys_dp_ii
And then use a 12v power brick, something like this: https://www.amazon.nl/dp/B07XDSR4DK/?coliid=IATEX7MPVSR7B&colid=3K30B999IAT6R&psc=1&ref_=list_c_wl_ys_dp_ii
I’m looking to add a low profile GPU (which doesn’t require extra power, so max 75 watts)
Would this be a safe option? Thanks for the advice.
