PCIE power cord pin layout for sleeving (Area 51 R2)
I want to sleeve the cables of my Area 51 R2. Because I'm running a single GPU setup, I decided to practice with the sparse PCIE power cord sets. In the process, I stumbled upon two questions:
- Are the PCIE power cord sets (cables from PSU to graphic card) interchangeable?
They are labeled with PCIE1 (or 2 or 3, respectively) on one side and with the corresponding connectors on the PSU on the other side: R1-R2 (or R3-R4 or R5-R6). Is this labeling just for the purpose of better clarity or is there a difference between the cables? I disbelieve it, and I could find non, but I want to be sure ...
(On the PCIE2 cable set there is also a warning label that reads "PCIE2 not available when using the 2nd 400W graphic Card". This is because of the 48 A limit of the 12 V rails of the PSU, right?)
- Are the pins of the PCIE power Cords are interchangeable, as long as you connect 12 V to 12 V and ground to ground?
At the moment, every pin of the 6-pin plug on the PSU side is connected with corresponding pin on the 8-pin plug on the GPU side (Two of the three grounds on the PSU side are connected with two grounds on the GPU side each, for the 6-pin to 8-pin conversion). But because the plugs face opposed directions, the wires cross each other. Can I switch them, as long as I keep 12 V and ground correctly connected? For instance, pin 1 of the PSU side (12 V) is now connected with pin 1 of the GPU side (12 V). Can I connect it with pin 3 of the GPU side (12 V) instead to avoid the crossing of the wires?

PCI-E cable has 8wires:
PSU end of cable has 6pin
GPU end of cable has 6+2:
Any yellow can go into any bottom row slot / any ground can go into any top row slot; be sure 2pins consist of a black jumper
Take a Grfx cable that has not been modified yet, and recreate it at both ends, understood?

all my 4 Cables have the same Dell Product Number (0JPV3Y). i guess it's just a Label and you can swap them..
messing with the Crossing Order sounds like a bad Idea.

It sounds like you have way too much time on your hands.
Try not to blow-up anything (Power supply, motherboard, or video card). Then, you will really have problems.

Thank you very much, this is what I wanted to know.
I already had watched Lutro0 (he is the sleeving-pope, isn't he?) and got my first PCIE cable sleeved before I asked this questions. I sleeved it one wire at time and double-checked it at the end, so I'm pretty sure that it will work as it is now.
But I want it to give it a more "cleaned up" look, so I think I will change the wires, even I'm still a little nervous about it ...

Time is not a problem, but I'm running out of fingers without scratches, cuts and/or burns ...

Just realized that because of the whole 6 -> 8 thing you cannot get rid of all the wire crossings. So I decided not to mess with the pin order at all and to stay with the little more "organic" look. Still as different as day and night ...

After I posted I didn't get back to the forum to see your picture or text but I can chime in now to lend help perhaps to your Sunday project, but it looks like you've got the gist of it, and if you have then I'll post this as helpful material for other people considering an individually sleeved project
I've made an individually sleeved cable set for myself as well; when the empty connex are posed as in the photo below with latches up, the wires are most easily plotted out as shown, to avoid tangles and 'crossing'
(Note: Grfx cable diagram below is for R2 850 / 1500w model only; any other make or model power supply or cable does not apply since there is no such thing as 'universal' power supply cables; other makes / models will surely be wired different @ PSU end and will probably also use an 8pin connector @ PSU end; example Seasonic may place 12volts in the top row of their 8pin design)
*Roladin uses red sleeve for the 12v wires so I've used red on the diagram (12v is normally shown as yellow)
From prior, any bottom row 12volt (left) can go into any bottom row slot (right)
For x5 grounds you get a single wire (#5) plus a pair of 'jumped' wires (4/6 left):
Optional: another wire scheme could put the single-wire into slots 6 while the jumpers / 2pin consists of slots 4 & 5
I realize Roldain's figured it out by now, but for those who haven't:
PSU end of connector shown = black ground jumpered wire-pairs (2 wires in one slot)
My sleeved paracord set found here: a Practical Approach to the Area 51 R1 Aurora Power Supply Swap
If you have more project pictures, tips and tricks, post them here for others
Owners who do not wish upon a do-it-yourself sleeving project, there are other ways to get a sleeved set like buying a new power supply and from there purchase a dedicated full set of pre-made cables as AlienAndy's done above, normally available for Corsair EVGA Seasonic etc in various colors and sometimes custom-ordered colors and sizes depending on the source (see CableMod configurator page etc)

I have to aggree with , your posts are very detailed and a great source of information. Thank you for taking the time to share your knowledge.
And that Area 51 in the last picture is a pure beauty. Just WOW ...

So I finally found the time to finish my PCIE power cord sleeving project. I used the alternative pin layout that Cass-Ole suggested, and it worked out perfect! So thanks again for the great input.
Still waiting for some cable combs to arrive, but I'm not disappointed with the look right now either:
