it may be going to the same 12v yes.
But.....
it's spreads the heat and doubles the max capacity of power over both sata lines vs just 1 on the y adapter.
and honestly. just a simple fix. it works very well.. and im just sharing.

3 reasons

1. all riser sets come with them
2. the sata chains usually arent long enough or the connectors spaced far enough apart to plug straight into the riser
3. most PSUs dont have enough single or double peripheral cables to supply all the risers (especially in 8+ GPU systems)

really the best solution is to use a server PSU with a breakout board. then you can power everything from a 6-pin directly with no adapters. that's what i did on my second rig, but its a lot more wires overall.

what's the point of using adapters off a SATA line?  Other than riser connection compatibility of course.  It's still a single 12v line back to the PSU.

been running my risers with 4x SATA to 6-pin adapters on my rig for months. all from a single cable. total of 8 risers, 2 PSU SATA cables with 4 connectors each.

also just to pour gas on this flame, running 2x PCIe 8-pin from a single CPU/EPS 8-pin powering 2x RX 580's

6x RX570s
2x RX580s
all underclocked/undervolted

can run 2 sata y adapters per 4 sata string off psu and power 2 1080ti's. no issue.
i guess i just had to do it all my self.

sata y adapters to 6pin work flawlessly with 1080ti......

simply put. if you got sata strings and not enough 4 pins for risers. use these y's and they work great. nice gauge, thick wire. feels good. tore 1 apart and it's all solid metal contacts.

i don't even think you clicked the link. cause again u can't answer clear questions... 

3a 3b 3c...    look at the Y adapter....  and input on how electricity works would be more then  wave ur hand ur doing it wrong approach ... ty.

Fail to plan, and you plan to fail.
1. dual 8 pin adapter off gpu. how many watts ? 150 or more. no one has a clear answer. i know that 150 watts per single 8pin is standard and it's well below it's max. but does the dual adapters that psu's come with just hanging on that same 150 watts (however it can go more because it's just the specification?)?
The 150W is for the cable, not per plug, so 75W per plug is the specification, most can do ~100w per plug easily, but dont push your luck beyond that.

Quote
2.dual 8pin on 1060 are safe (going off question 1's answer 1060's - two should be hitting your 150 watt rail not hard as it's maximum is higher much anyways).  how about 1070. i guess it depends on card? thoughts?
No 1060 needs dual 8 pins, or 8 pin + 6 pin, plug in the primary 8/6 pin and thats it, enough wattage for the card. 1070's can get by with one 8 pin as well, you only really need two with 1080ti's and Vega 56/64 etc.

3a. dual sata female to 6pin. does it pull power equally off each sata port?  https://www.newegg.com/Product/Product.aspx?Item=N82E16812400106&cm_re=dual_sata_to_6pin-_-12-400-106-_-Product
Again, the spec is for the cable, not the plug so 54W total for the cable, can be pushed to 60w but not recommended beyond.

Quote
3b. can i use 1 sata string cable from psu with 4 male connections and use 2 connections of 54 watts(per sata adapter specs) to get a total of hopefully 100+ish draw. or do i need 2 separate sata cables. from what i understand the sata plug (just the tip not the wiring) is only able to allow 54 watts within it's limitation but if i use multiple plugs (***on the same cable***) does each plug have it's own rail is what im saying. if so that would make all those 4 port sata plugs useful in some sense.
DO NOT - repeat - NOT think of combining sata/molex to 6-8 pin kinda shenanigans unless you want to burn your cables/cards.

Quote
3c. if 1 molex string from psu can power usually 2 1080ti's. or 1 if u overclocking. then technically if 3a. is true and it equally pulls. and 3b is true separate rails. then can't a single 4 string sata cable from psu, with 2 y adapters of sata going to a 6pin, be possible???    my main point is im lacking molex plugs on my psu. how can i use the sata's effectively. now i wouldn't run 2 y adapters on a single string, but if molex can run 2 on a single string. why can't sata, im guessing it matters about gauge wire at that point? im assuming the equal pulls and different rails and gauge all factor in to this. but this is advanced knowledge that is hard to find and only real people deep in the mines who messed with adapters know and i would love some info...
Nvidia GPU's typically pull very little power from the PCIe slot, so the you can use 2 risers per cable be it sata or molex without any issues. But if using sata, us the Sata power type risers, stay far faaar away from sata-molex or sata - pcie power adapters that come with other risers. Also, DO NOT connect multiple risers to one cable when using AMD cards, they have notoriously high power draws on the PCIe slot.

4. My problem is i got 4 dual pci rails off psu and 3 1080ti's plus 2 1060's. the 3 1080 ti's using dual pci express 8pin adapters. the the 1060's sharing the last dual 8pin. the peripherals  that came with my psu are 2 molex strings and 5 sata. how should i power my 5 cards, best options???. my opinion would be all 5 cards get there own 4 pin molex but i do not have that. more or less. can i use 2 risers per molex string for 1080ti? should i do the y adapter from dual sata to 6pin on the 1080ti's..    (i got some crappy unsafe sata risers but 1060s draw such little power that it's ok to use them on them .1070's can be a different story however).. regardless that 3rd 1080ti how should i go about powering it if i only got 2 molex strings.  Now it's obvious if i had the equip in front of me i'd be trying out stuff. i got a grasp of being safe with 1060's and 1070s. i just wanna make sure without blowing money on all different adapters i just get the info i need for 1080ti's and be done with it.. you guys know whats best. and it's obvious my answer should be a simple do this as i know whats up Smiley.
You have 5 GPU's to power, you can use 2 molex powered risers per molex cable making a total of 4. For the 5th, get a sata powered riser. DO NOT USE ADAPTERS.

5. F it all , if adapters don't work and 3abc all is shit. how do i just buy more pata's for my psu. the website sells hx wires but not separately for the higher watts versions.

Lets keep this page informative, as there is a lot of bs info out there on this very subject and others are in the same exact boat with me as to questions on how to go about the lack of PATA 4 pin molex cables in their below 1500 watt psu's.   the question is what do i do. what is best. all these dam sata strings. are they all literal trash or can we retrofit them to 6pin or .... again. what do i do.
This isnt a "Page", this is yet another "Help me bro" thread created because someone is too lazy to read through the forums several threads covering THESE EXACT QUESTIONS.

8-pin from PSU (standard terminals) can handle 288W.
From my PSU (EVGA G2 1600W) I have 8-pin cable that splits into 8-pin (powers radeon 570 GPU) + 6-pin (powers riser).
(Each PSU handle 6-7 GPU + risers. The one handling 6GPU+risers is also handling motherboard, cpu and ssd.)

Some will do 150
Some will do 200
Some will do 250
Few will do 275-300

Some 1070 are eight pin dual with 180 tdp most all won’t melt a dual 8 pin pcie cable.

Can not tell as I do not have a good view of it.  But I think not from the view I see
3b. can i use 1 sata string cable from psu with  4 male connections and use 2 connections of 54 watts(per sata adapter specs) to get a total of hopefully 100+ish draw. or do i need 2 separate sata cables. from what i understand the sata plug (just the tip not the wiring) is only able to allow 54 watts within it's limitation but if i use multiple plugs (***on the same cable***) does each plug have it's own rail is what im saying. if so that would make all those 4 port sata plugs useful in some sense.


The one you link looks to have a 2x draw on 1.  And a 1x draw on the other.

If I am right you can only balance if you feed it from 1 sata cable using 2 connections .

If you feed from 2 cables it will draw harder on one cable then the other

And if you downclock your cards with power limit, 1000w should be enough for your rig given you buy some quality psu like evga, seasonic or corsair. 1200w is of cause better but is way more expensive.

Make sure you power limit your 1060 cards if you use one power cable for two of them.

Yes you can use two risers out of one molex or sata cable from psu. By book you should not but actually you can. I use them this way for half a year and they are ok.

And you can use one pci-e power cable for two 1060 cards. i did this on two 1070 or 570/580 cards no problem.
