PSU pinouts

[BrodieH]

I want to make custom sleeved cables for my power supply, but first I need a pin out so I don't blow anything up. My power supply is the EVGA supernova G2 650w. Does anyone have any pin outs already or any ideas on how I can create my own pin outs? Thanks in advance for your help.

dont forget to check the voltages with a multimeter too

thank you for the help, however this the the supernova G1, whereas I have the G2. I'm unsure if the pin outs are the same, so it would be useful if you or someone could tell me how to check the voltages with a multimeter

get a multi meter

set it to voltage (DC)

set it to a voltage above 12v

turn on your PSU

plug the red one (positive) into a positive one, and plug the black one (negative) into ground

Are you sure you want to spend a week cutting cables and spending hundreds of dollars on tools and materials?

Maybe you should buy a custom cable kit instead which will look much better than what you can do at home, and it will cost less.

I'm going for fully custom length cables that are the perfect length for my build, so yes it is worth it. once you have bought the tools it is actually cheaper to make them yourself also

A. It does not cost hundreds of dollars to sleeve your own cables.

B. Cable Kits are low quality compared to custom hand made cables.

C. What is created at Home will always look better then mass produced kits (As long as you know what your doing).

Take a look at the default cables that came with your PSU and you can follow that pin layout. Those cable are always the most current version of the layout. There should be atlease two to three Y cables (aka Double wire). Soldering will be required to create those cables.

Creating your own pin layout you will need a multi meter & also a PSU tester.

A. It does, all you need to do is add up the cost of the wire, sleeving, connectors, pins, crimps, heatshrink, wire cutters, wire strippers, etc.

 

B. Nope. Take a look at cablemod stuff, higher quality than you will ever be able to make.

 

C. Haha, watch this video:

Unless you do it hundreds of times, it will never look as good as something done by cablemod or singularitycomputers.

Cablemod does exactly that. For much less headache.

A. Actually they don't. Most supplies can bought at a decent price. It will never cost hundreds and hundreds of dollars, I suggest adding up the supplies. It never cost me that much to sleeve all my cables.

B. I suggest you take a look at my cables, CableMod uses OEM terminals. Using MDPC-X Sleeving & Molex terminals your already leagues above anything Cablemod makes.

C. Why? I know how to sleeve cables. Singularity Computers are hand made just like most do it at "Home". My Cables looks better then anything CableMod makes.

Haha, those are some great jokes

It is definitely over $100, unless you use scissors to cut and strip cables, buy chinese quality sleeving, and the cheapest crimpers you can find on ebay.

Also, you seem to not understand the difference between custom cables made by someone with many years of experience, and the cables made by someone who has never done it before (OP).

Maybe take a while to think about it, you may come up with a different opinion.

Do some actual research before stating this BS. Even first timers can make amazing looking cables and They look better then anything CableMod makes.

 

Anyone who states that you can not make high quality sleeved cables at "Home" does not know what there talking about.

I made my own cables for about 1/2 what cable mod charge. I used all molex terminals and 16AWG wire from TE Connectivity.

 

I already have decent wire strippers, cutters, soldering iron and mulitmeter etc, as electronics is both my job and hobby. These are not factored into the cost.

 

It was my first time doing it. The first couple of wires were a bit ho-hum, but I did the ones that were largely out of sight first and got quite good quite quickly. I didn't use a crimp tool and got very good at crimping the terminals by hand with needle nose pliers. Despite this, the cables turned out really well. It took me 3 days to sort everything out, and that included some troubleshooting as some of the CPU pins weren't making proper contact for some reason (nothing to do with the cables.) I didn't use a PSU tester, and instead spent 3 hours checking continuity and voltage output to ensure the cables I made were exactly the same as the stock ones and the outputted voltages were the same as the stock cables. I would highly recommend DIY as it means you get exactly what you want. Even using cheapo Chinese paracord I managed to get

a really good result. Although the MDPC-X sleeving looks superb. I might have to get some of it.

Totally agree. I have heard alot of people say they like cable mod stuff, but everyone who actually looks at how it has been built or manufactured doesn't have nice things to say about them, and they are really expensive compared to other options. I worked out once that their LED strips cost 2.5 times what I can buy equivalent products for elsewhere.

I am in agreement with the others, there is nothing to say that you cant build your own quality cables at home. I did it for my recent build, and even though it was my first time sleeving, with some practice, they came out just fine. And one thing no one has mentioned is the satisfaction of knowing that you created something with your own two hands. For me, it did cost more than a kit, but that was because I chose to buy nice tools, and the supplies that I wanted (Primochill Kobra Maxcord, in my case).  I wont say that cablemod is bad or anything, but how can you deny the value in creating something yourself?

 

How about instead of fighting over this, we actually help the OP with his question?

  

When sleeving my HX750i from Corsair, I couldnt find a pinout online, nor did I have any metering tools. I just looked at the stock cables, traced the paths or the wires, and diagrammed them out on graph paper, using pairs of numbers instead of voltages. I think that may be the easiest way for OP to get their pinout. 

Another tip I have is to use transparent heatshrink for finishing the wires, as you can see when the sleeve melts, so you can pull off the headshrink at the right time. Before that I had trouble with knowing when to take it off.

I used this for initial reference:

 

http://www.overclock.net/t/1420796/repository-of-power-supply-pin-outs

 

However when it came to actually making the cables, I used a multimeter on continuity check to copy the stock 24-pin, and used continuity check and voltage measurements with the supply running to work out how I needed to connect the rest of my cables. I actually found on my EVGA supernova g2 850 that the two GPU and CPU power cables that came in the box had different pin <--> pin wire connections but outputted the same voltages. This was due to wires carrying the same voltage being switched. It made no difference to the functionality of the cable, but made it harder to copy.

 

I would recommend getting a multimeter to copy your stock cables, that way you will guarantee that you have used the right pinout. For EPS, and PCIe pinouts, a quick google image search does the trick. At the end, either spending 3 hours (ish) checking continuity and voltages or buying a PSU tester is a good idea. I used my old Pentium machine to check nothing was amiss before connecting the cables to my ryzen rig.
