I just wanted to know if any 8 pin atx cable will work with any atx PSU. It's because I just sleeved a 8 pin cable, albeit sleeving it poorly (first time), and I want to test it in a working computer before I sleeve the rest to make sure I didn't damage anything in the process. Also, lets say the cable isn't working, and I plug it in, would it ruin anything? And if it makes a difference at all its a 8 pin PCI-E cable from a Corsair 1050HX. Thanks!

What do you mean by touching wires? All the wires had a coating, they weren't bare

Lol yes, I suppose that :D but what I meant is you could look if the coating didn't melt and the copper wires are touching, although it's not very likely to happen.

No, I'm not using any connectors, haven't built the rig yet

That clears things up. Then you could use a fresh connector and sleeve it. Unless you have quad-SLI/CF, there should be enough PCIe connectors.

I'm a tad bit afraid of sleeving the CPU connector now, but would I be alright as long as I made myself a diagram and connected it exactly as before?

Almost every PSU model has its own design for modular cables, so it shouldn't even fit. Even if it fits, there's a chance the connections are different so it could damage something.

The only thing you could have done wrong is to plug the wires differently back to the ATX plug. In that case the PSU would survive it thanks to its protection circuits, but I'm not sure about the graphics card. But if you're sure you did it right and didn't burn the cables to a crisp, it should work.

I checked my cables to another one I didn't touch, one side has 6+2 pins and the other side (one that goes into PSU) has seven pins. The 2 on the 6+2 go into one in the blue seven pin. That one I plugged back exactly like the stock cables, but would it matter about the configuration of the other six pins? Aren't all the wires just wires and it only matter what current goes through them?

Also, if I do on the off chance fry my GPU, would that normally be in the warranty if the PSU fries it? They don't have to know it was my wire.....mwahahaha

Edit: Oh and as for the burning to a crisp, the heat shrink is a bit black on one wire as I used a lighter instead of my heatgun on it, (silly me),
But I'm pretty sure the wire is fine. Is there any device that I can plug in to the 6+2 pin side and plug the other side into the PSU to test the cables?

Partially right, the black wires are ground, while the yellow ones are 12V.

So just be aware of the colours.

If so, it's a case of warranty for Corsair then. And I don't think they won't recognize a false wiring.

Dude, no comment :D
Btw I use lighters for shrinks too, but you have to heat it in short and quick.

Is there any device that I can plug in to the 6+2 pin side and plug the other side into the PSU to test the cables?

No, at least not a less expensive one than a graphics card, except a cheaper graphics card. But really cheap cards don't need extra power from the PSU.

Either you try it out or if you are unsure, here's what you can do:
1. Buy new cables from Corsair, I'm sure they're selling them apart. If not, you can contact their support and maybe you can get them for free if you'll do it cleverly.
2. Buy a cheap, old generation graphics card with high power consumption on ebay and try it with it.
3. Buy a new graphics card and try it with it. If it works, you can send it back. But if not and it gets damaged, it would be really rude if you would send it back and claim you've got a faulty device. That's why I wouldn't advise that to you.

;)

Is that diagram universal? Because I saw something in the corsair PSU manual referencing what each pin did, going to check it again. Also, Corsair, in their infinite wisdom, made all the wires black, no yellow. After I removed the stock sleeving, each wire was black, and each one on each connector didn't necessarily correspond on the other connector. Ie, the top left pin on the black connector wasn't the top right pin on the blue, it was mixed up. Since all the wire's were black, and now I don't know where the original positions were, would it be fine to just correspond the pins on the black and blue connectors with the same configuration of an untouched cable? Like if on the stock one, bottom left on the black goes to middle right on the blue, would just rearranging the pins on the modified cable to the same as the stock be alright?

Right, with 1050W there's more than one PCIe cable, how could I not think of that. Of course, just compare the wires with the untouched cable, then you should be fine.
You could also remove the sleeving, look for the connections and look if there are blank wires touching and do the sleeving better than before.
Are you using all of your PCIe connectors from your PSU currently?

No, I'm not using any connectors, haven't built the rig yet, I wanted to sleeve all the cables beforehand. What do you mean by touching wires? All the wires had a coating, they weren't bare. Some of the wires do touch, not the copper part, the outside material, as I didn't have enough small size sleeving do all the cable wires individually, and had to do two per sleeve. Eventually I'm going to have to do 4 per sleeve as I'll run out of the medium size if I continue with the rest of the cables. I'm a tad bit afraid of sleeving the CPU connector now, but would I be alright as long as I made myself a diagram and connected it exactly as before?

Yeah, I'll just re-arrange the pins on the sleeved ones to match the stocks, and I'll sleeve a new PCI-E to be safe and the CPU cable with diagrams. Does it matter which wire goes where or any wire, just in the right config? Just asking because I feel that it would be hard to mark the wires while sleeving. If it only matter by config, I'll just draw up a diagram, remove all the pins on a cable, sleeve, then re-pin according to the diagram. Does that sound safe? I'm probably going to save the one I have sleeved already to test in the future.
