SATA power cable problem

[mitsosvazelos84]

Hello , I just finished my sleeving , got my mobo and gpu cables working ( after some troubleshooting ) , and then I checked on the hdd and sata cables .

But the cable wont give any power to the hdd , none of the two rows of sata will . I double checked the cables , found an error with the allingment of the sata cables ( the yellow wire and the black wire finished in each others destination in the next connector ) and fixed it . But nothing . I also tried powering up another hdd to be sure , but it wouldn't power it either , so it is deifnitely a cable problem . Can you please help me solve this problem because it is driving me up a wall .



thank you in advance ,

do you have a voltmeter or multitester to confirm the wiring is correct?

hmm, can't get link to work, search there for 'sata power'

I got a voltometer , but even if I detect any problem , how can I fix it ?

you said the yellow and black wires were reversed in one of the connectors, it wouldn't hurt to double check that you fixed the right (wrong) one.

Ok so will check how to measure this . i have a feeling though that my cables aren't in the right place in the connector . do you know were the ground , power etc. cables go in a sata connector ?

EDIT: I found something . the arangement of the cables counting upwards from the little notch ( positioned in the side of the connector ) is ; Red -> Black->Yellow->Black->Purple . the normal layout that i see on my second pc and pics on the net is ; Yellow->Black->Red->Black->Purple . Does that yellow and red swap make a diference ? I suppose that I shall reconect them the proper way and see how it goes ?

pin 1 is closest to the right-angled end of the connector, and this is how each pin should be:

I have been advized from the very same pinout 😛 as soon as i get to my pc I will try this out . I guess I don't need the voltometer now , since its just a misplacement of the wires .

thank you for the help

Ok so I fixed the wire misplacement , but unfortunately nothing . No power via sata . Any thoughts ?

I will try the voltometer next time I get to that pc .
