Looks like SATA power will suffice. Molex power is optional.and looks like need to input that molex power to work

Thank this answer! Unfortunately, there are no concrete results that I am worried about.
Thank!
Looking into a low-cost M.2 PCIe adapter. Don't need bandwidth greater than 1500 MB/s. Can I safely use the adapter (i.e. not risk overheating) in the link below WITHOUT installing the heatsink and silicone pad? Will be installing a Samsung 1TB 970 Pro NVMe M.2 in a macpro5,1.

Thanks much!

Don't do this. Unless you live in a freezer, your 970 Pro will overheat.

Lol, thanks. Alright, any thoughts on the quality of this [low price] adapter installed with the heat sink and silicone pad?
Also, plan to install the 970 Pro NVMe with this adapter in slot 2, just above my GPU (GTX Titan). Heat issues with that?
Some people here have this adapter, but I don't have any experience with it.
I have a 970 Pro with a SSD7101A and even with that enormous heatsink fan combo, the 970 Pro is around 47º to 50º when in constant use. I tested it with my Angelbird Wings PX1 and got around 50º to 55º when cloning another SSD to the 970 Pro.
Don't use it without a heatsink, your Titan is a little hotter than my GTX 680.
Do not healtsink do that? Does this adapter have with 970evo speed of 16x for ~3000/3000Mb?
@5050 asked:
Only PCIe adapters with a PCIe 3.0 switch can get over 1500MB/s. Do you think that a adapter that cost $13 will have it?
The cheapest PCIe switch, just the switch, when bought 10.000 units cost $130 per unit, the cheapest complete card bought directly from the manufacturer, in China, cost around US$ 180 (IOCrest).
People are buying it cheaper from AliBaba, not AliExpress.
OK, just bought it and also bought 2 512GB 970 Pros. I told myself I wasn't going to put any more $ into my 5,1, but there you go. If anyone is interested my Apricorn Velocity Duo x2 will be available soon!
I'll be moving my 2 2.5" 840s to the HD bays. They will be replacing a WD Black HD and a Seagate Hybrid drive. No more platter drives for me!
I'll be keeping my 512GGB AHCI SM951 mounted in an Angelbird PX1 and the 2 840s already in the HD bays.

Me too ! I only have ONE platter now in my cMP.
Can you possibly post some performance info on the Iocrest?
Two x 512 970 pros is definitely going to be faaaast !
Have a MacPro 4,1 upgraded to 5,1. Latest Mojave, firmware is @ 140. Just put in a WD Black 1GB (in an Angelbird Wings PX1). Its in slot 3. Boots just fine, but only getting about 760 MB/s read and write. I would expect about twice that. System report confirms 4x and 5GT/s and TRIM is on.
Any ideas why its running at about half speed? Here is the item. If I’m reading the specs right, it should be faster. I know its not going to get 3400 in a PX1, but it should be better than 760, I’m thinking.

Thanks to tsialex for directing a bonehead to the right thread.

Yes. SeriTek 4 port eSATA card. It’s also a 4x card.
All slots are filled, in fact.
Slot 1 is AMD Sapphire Pulse 560
Slot 2. Blackmagic Decklink Monitor. Its only a 1x card, but it’s placed here for better airflow to the graphics card. Its tiny and doesn’t block the fans at all.
Slot 3 is the PX1 with SSD
Slot 4 is the eSATA card.
Remove all other PCIe cards, except the GPU and check again, but WD uses the name WD Black for various types of NVMe blades, some are PCIe 3.0 2x and the throughput of these are 750MB/s into a Mac Pro 5,1.
Other users here got the same speeds before.
That’s interesting. Will try that later today. Not in a position to remove all the cards at the moment.
Out of curiosity, how did people determine that? I don’t see that info anywhere on the spec sheet.

Much appreciated.
