Seasonic: I looked all over your site. I found diagrams of your new cables, but I found no photographs of them. Am I missing something?
The physical connector looks the same, it's about a change to the pinout and actually using a pin that was normally left unused or just a ground wire.

Those monster 6-12TB HDDs that you can buy these days require a complaint cable and while it is present on some units it's not as widespread as it should be. Some drives won't start without the proper wiring of the connector while other drives won't have access to their power saving functions. Depends on specific make & model.

This is for datacenter SAS disks.
For retail drives, companies would include Molex to SATA adaptor. And the retail market share of these drives is thinner than a human hair.
The PSU industry (ex-Seasonic) will not ship again SATA 1.0 connectors without 3.3V. Most drives do not use the 3.3V anyway, but shipping SATA 1/3 connectors instead of SATA 2 is stupid for the retail market. It would just cause mayham.

Correction: Seasonic seems to include 1 adaptor, but ships SATA 2.

I'm sure the fact that Seasonic hired on a whole server team this year has a lot to do with this.

We wont even include the adaptor, it would be included in a SAS. And we dont sell too many units to data centers. Seasonic is obviously just picking this for marketing since they include 1 adaptor in non-IPC units. I wonder from whom they learned this
I still feel guilty how eSATA in cases was such a obvious screw-up for end users, but the best invested USD 2.4 on a 90 degree tilted eSATA cable for Enermax. Chakra sold like crazy

And for their IPC team, they sell normal IPC stuff which neither needs "PWDIS", they are not Emerson.

Anyone,

Do ALL NVMe drives use PWDIS?

Answer to self,

NO, they do use 3.3V. Like Seagate Nytro 5000 NVMe up 7W read/write - 8.25W max = 2.5A max for one drive

What are 180 degree SATA connectors? How do they look like on power supplies?

Normal


Picture 180 degrees turned. First one works best if you place the PSU at the top of your case, second one works best is you place the PSU at the bottom of your case.
