How to use an ATX Pinout Diagram for Custom Cables | bit-tech Modding

Since a few folks were asking about this in the community tab post, I figured it would make a neat little video to round off the week. Using a pinout diagram really is quite straightforward, as long as you know why you need one.
If you'd like to download the template and fusion file mentioned in the video, head to the GrabCAD link below. Additionally I've also added complete pinout diagrams for both the AORUS P850W Gold used in Ensis, along with one for Corsair Gen 3 Type 4 PSUs such as the RMx/SF/RMi units.

I have waited for this kind of video for over 3 years. Its tue only reason Ive never done cable sleeving myself

[@tonka8080]

That’s really pretty simple once you get the hang of it I’ve been making cables for about eight years I love it

[@lnrdrpd]

This channel is so underrated. Keep it up, mate!

[@xxJOKeR75xx]

you actually inspired me to do my own cables last year and it was a little confusing to find the required pinout sheets and using them. I found it very intimidating at first but i checked with a multimeter and all the voltages where fine so i risked it. It's just a small mod compared to what you're doing but it's very satisfying.

[@anchitrao386]

Was always really intimidated by the idea of custom cabling. The effort and the possibility of things going wrong was always too high for me. This video gives me a bit of confidence, and seeing as I'm slowly getting into modding, I'll be sure to use it as a reference in the future. Thanks so much!

[@haloshiroe]

Instead of manually tracing the cables, I would recommend instead using a multi meter continuity test, this is probably a much better approach (I know you made an offhand mention, but I feel this is more important.)

[@ramonflorezjr]

is there any map to test continuity that you can show?

[@AcerTheRed]

Wow, good timing. I was also curious about that pin-out diagram but was too lazy to do further digging. thanks.

[@The1PatSmith]

Thank you, Alex. Stay well.

[@michael-rommel]

Looking forward to the further journey of Aquaceras... Thanks for the downloads, mate!! Very good, enjoyable content on your channel!

[@GarrettC8450]

Uploaded right as I've started getting into modding, nice lol

[@X2Broster]

Thanks for providing. I created the diagram for my Straight Power 11 cable with a multimeter so as not to destroy the original sleeve. The visualization of plugs has often confused me because you have to think 180 degrees, so I visualized the sockets of the mainboard and PSU on the sheet.

[@hoyle038]

Thank you so much!!!!!! This was a much needed video for DIY'ers.

[@onlyy823]

Nice! PC World exactly need such kind of information 👍

[@kitsune2858]

I have been DIEING for help on this :)

[@maggot4953]

I rly enjoy your videos a lot, keep up that great work - And thx so much for giving these files to us for free!!!

[@homerogonzalez2909]

ur a LEGEND thank u for the diagram! i hope the corsair rm diagram also applies to the AXI series 🤞🤞

[@albert30300]

Great info - Thanks!

[@chaadlosan]

Always a class act.

[@triggerhappysound]

I've watched god knows how many pc building/upgrading videos. I can't believe that I've never heard anyone say that you can't swap cables between power supplies (since they appear, externally, to be standardised). Seems like quite an important piece of information for folk to know since someone might well decide to just re-use the cables they already have if they change PSU or something. Eep. Anyway, really interesting video, thanks!

[@phyranios9091]

Certain ones you can get away with but you would have to be incredibly lucky. I think all manufacturers should just standardise them

[@GabbyTech]

very precious info well explained ty ;D

[@H3rr7w3rg]

Nice - thanks :) Stay healthy

[@CrtopherCR]

Hello, by chance there is a video of making the strainers or there is a template is the structure to put it on the pc and separate the cables. the videos are magnificent

[@joshpeck6039]

Love your videos. Very informative Could you adjust the volume of your oppenings. They often come in way to loud. Especially compared to the rest of the videos

[@konan1468]

Wow this is really helpful, I’ve always been a fan of clean and organized custom cable. Just wanna ask what does the color on the diagram indicate? Is it the one you’re talking about that can be interchanged?

[@davidmcglynn2765]

I've just gone through this myself as well. The fact the ATX standard covers the motherboard side and not the PSU side is criminal. I got lucky with mine though, as it happens Silverstone PSUs are 1-to-1 with the motherboard so it was easy to match up

[@vasilioskapousidis8675]

Great builds! Looking to make custom PCs and water cooling components for PCs and laser cutters. What CNC do you use?

[@ubermacht1984]

That is a very helpfull video. Thanks. I was Wondering why my PSU wasn't powering up after swapping. That moustage acts distracting though. xD

[@Lucas..23]

I am looking to build a custom case for my computer that I have now. I cant measure any of the parts. Could you please make a tutorial on how you make your mods in Fusion 360.

[@kootaalzamili1707]

Can I switch cable pin out for pcie ground for better cable management

[@phillipzan2005]

I had a semi modular PSU. I wanted to have full length cables. I had to disassemble the PSU, map the wires, build a diagram, Cut the wires to the length I wanted & then build the pins for them. Custom wiring the you build from the ground up is so time consuming on any thing.

[@ryanmichalski7420]

I am looking to make a custom 2 pin power switch do you know if the pins are the same as the axt cables.

[@bageland2000]

Is there anywhere I can go to learn the Photoshop basics of how to edit the template to add the PSU side numbers/colors? I'm not savvy enough to accomplish that.

[@HeyHeyIamYourFreind]

You Are the MEN finally some one explains what is a pinout connector and how to do it , every other youtuber shows how to make the costume cabels but doesnt explain about the pinout, you got a like and subscribe from me 👍

[@nikolas7615]

When switching around wires, Isn't is possible for one 12V output to be able to supply more Amps than another one, depending on what it is used for on the motherboard? Or are MB manufacturers not using the same pins for the same components as well?

[@Cristiancr1ogenMachado]

The diagram of the power supply of aorus 850 is the same from the aorus of 750 model?

[@stevepap1333]

bit-tech hi my friend. If someone have for the EPS ( mobo side ) one 8-pin + one 4 pin in motherboard?? Your diagram ( pinout ) does not show how we can fix it. Any help??

[@matthewwilson3673]

do you have a link to a pinout for evga? I have a 550 gm sfx unit and none of the pinouts I find are numbered or show voltages especially for the mobo 24 to 18/10 connectors

[@omfgximjustin]

When you say pins of the same voltage can be swapped, does that mean in the pcie-8 pi that the 12v and ground cables can just go straight across except for the double wire in 4,8 position? I see in your diagram that a couple of them cross. I have a desleeved cable for a corsair ax760 that also has crosses, but they are not the same as shown in the diagram.

[@BowtieMan4Ever]

Does anyone know why the ATX standards do not require manufacturers of PSU’s to map their wires the same way?

[@dbcustomtowers4757]

Is there a way to test the cables, if you're making them for someone else and you don't have the power supply, just the pinout?

[@marcellipinski8929]

First of all be sure to have the right pinout. If this you have the right one it's the best to check it with a multimeter one connection after another. Just be patient and mark every right connection to the pinout. At least that is what I've done on a daily basis to connect machines with far more pins than 24 or 28.

[@ryzuu9640]

how pinout thermaletake smartpro ??

[@phillipzan2005]

bit-tech out of curiosity what seize cable do you use and do you have specific place you get them from?

[@anomalousresult]

mdpc-x is a one stop shop for everything cabley

[@bittech1]

I used to shop around but now I just use MDPC-X for essentially everything other than peculiar niche connectors. I really like the 17AWG wire from them, it has a large core but slim insulation, so has similar total dimensions to 18AWG. I used to use 16AWG but it's trickier on the pins themselves, it's also harder to use with distro plates etc. since the holes need to be larger.

[@phillipzan2005]

@@anomalousresult I already use their custom sleeves which I love I just wanted to see about cables. I get a little mind blown on how expensive they can be for wire. Considering construction wire and special flexable cables is cheaper. I just don't want to use those any more cause the are hard to bend in tight spots and/or have thick insulation.

[@phillipzan2005]

@@bittech1 yea I used some local construction white cable. It has a close O. D. TO MDPC-X. 16awg I found is a pain to pin up with sleeve in the connectors. Other down side to the cable I used was it has to many strands so tight bends suck hard. So I am going to redo my cable job with some other cable. Hence the question. Luckily my custom cables are way longer then I needed them to be so I'll have enough MDPC-X sleeve to redo 90% of it again. The other 10% I made some weird choices in hind site.

Do someone did find a 12 pin NVIDIA rtx3000 to 8 pin diagram ??

[@1440PGamingContent]

I wonder if you can combine an ac system converted dry with pneumatic air cooling. I see these cool robots at work that need this generator :p

[@flamingducky8221]

i just sleeve the original cables that came with my psu and then i dont have to worry about pinout diagrams

[@Bunyaminozb]

Targaryen Themed Pc Build Pleaseee ❤😊

[@black.phoenix.]

I prefer to create small converting plugs, so basically the same as the cable but in shorter length, less than 100mm and then extension at 1 to 1. Since the small length are normally hidden close to the PSU, the only thing that is shown is the beautiful parallel run from the extension cable. Something like this cdn.shopify.com/s/files/1/1207/2332/products/Untitled-1_large.jpg

[@willthepotato]

sponosred by CORSAIR

[@JamesCoyle95]

I find it really stupid that this is even an issue. The connectors should just be the same (or at least map 1 to 1 with no crossed wires) on both ends of the cable so you can never mess things up.

[@bittech1]

In an ideal world where we cable makers mattered, definitely. The issue is that by using different pinouts on the PSU side, OEMs can achieve higher efficiencies and ripple control without vast expense. At the end of the day consumers will choose the unit that reviews with tighter figures for a lower cost.

[@IIGrayfoxII]

From what I have seen most +12v lines are tied together so instead of having +12v then +5v then +3.3v you just get all of the voltages tied together internally on PCB. Separating each pinout for its own voltage will just drive up the costs of making the PCB.

[@ared18t]

Why are subtitles set to dutch auto generate and translate to english lol they don't work

[@TheLukemcdaniel]

Would it have been so fucking hard for it to be a 1:1 from one end of the cable to the other? Were they /THAT/ afraid of some 3rd party stealing their profits by putting out their own replacement cables?

[@jonathanlarsen4177]

They need sense wires. The double wires he mentioned exist so the PSU can know the voltage it gives out to the components. Some Power supplies also use the sense wire to control the fan speed of the fan in the unit. Engineers aren't dumb y'know

[@TheLukemcdaniel]

@@jonathanlarsen4177 it can check that on the internals. All these need to be are fucking extensions.
