Do I trust this Corsair Type 3/4 Pcie Cable?

hi

really hope someone can give me a clear answer on this one. Am using a second-hand Corsair 750w psu (TM) for almost a year now and all is good but wanted another pcie power cable as it only came with one and heard to use two cables from psu if gpu had two 8 pin connectors required. I have ordered and received one but when I checked the pin layout compared to the existing one plugged into the psu I notice that the 'empty' pin in the new cable is different - the new cable its 'bottom-right'.

Weirdly I checked the Corsair site before I bought cable and it says 'type3/4' are same and looking at other sites with pictures I can see the new cable I have bought is the same as everyone is selling but why is my existing pcie power cable layout different to my new one?

I dare not connect the cable to my psu until I feel it is safe to do so.

Thanks for help.
 
If the pinout is different to the existing pci-e cable then don't use it or you could kill something. What you could do is move the wires to match the ones in the existing lead. Although it makes things easier you don't actually need a special tool to remove the pins from the plug as you probably have something around the house that you can use. There should be some guides on de-pinning on Youtube. Just remember to pull the little locking tabs back out before you re-insert the pins in the proper locations.
 
It appears that all the pics of pcie type 3 or 4 cable the same pin layout as the one I have just bought but the one already fitted to my psu is the one that's different?

I was just ghoing to ask a very similar question.

I am changing a few PSUs about in my systems, mainly cos I got a decent PC with a little 600w and for some rteason I threw in a 1000w XPRedator into an old Core2Duo that I never use, and I have also got a Powercool thats kind of sat here doing nothing, and well...

The thing is, that the Powercool I cannot find ANY of its cables, or at least I dont think I have... It has Some Black ( 6 pin ) sockets and some blue ( 8 pin ) ones.

The Aero has Red ( 8 pin ) and Black ( 6 pin ) and the Corsairs all have black.

Now, I found the corsair cables as they are in bags, so I have kept them, together, and annoyingly I have a well organised setup with boxes of cables X and Cables Y asnd so on, and so I should have the others, but I dont.

Now, I have also found Type 4 ( Corsair ) and type 3 ( erm? ) and so what type is the Powercool?

Im ok with a soldering Iron and I have plenty of adapters and I could rewire it, but I dont know what to wire up?

How can I find out what type the powercool PSU is? I have had a bit of a look, but I am flying blind.. Sorry to hijack this thread, but as its so close to my issue...

Thanks.

Oh, a small addition... This is only a thought, but is type 3 and type 4 essentially the same, but one has the 3x2 and the other has the 4x2 sockets for GFX cards?

Im just wondering because I found one that has type 3/4 and it has the extra 2 pins that can disconnect for it has both the 3x2 and the 4x2 plugs on it.

That would essentially mean that type 3 and 4 are ( for my needs ) the sam,e as I only need 2 of the 3x2 plugs and the 2 extra wires are unused?

There are also some differences in a pin or two missing from the cables and the pins are different.

Ill have to see what pins are missing, but this still does not solve my issue on whether they are all compatible and I am not convinced of anything right now.
 
Another addition.
I just found a couple of cables that have the same 6 pin ( 3x2 ) plug on one end and 4x MOLEX and one if type 3 and the other type 4, so yes, they are pinned completely diferently.

I have also found a doubler that converts a single 4x2 into 2 4x2 plugs and also a blue socketed 4x2 cable, so that does sort out the Blue PCIE connections for me, however it also means that the Black sockets are now questionable?

I think I wont bother risking anything until I know the actual type that the Powercool PSU uses?
 
Mmm... I wonder.. Is that why its sat on the side here? Usually, I would have used a Modular PSU over a NON Modular, but this was in one of my empty cases and so I thought I would use it...

Especially as I am sorting out my ITX cases, they need to be a lot tidier.

But yeah, in the end I just gave up and swapped them with different PSUs, and the non modular I put into the older system and just cut a few wires instead of folding them up.

I will keep the PSU however. I know me... Ill chuck it and then Ill find the cables for it once its gone and then Ill find a need for a PSU. and you know how it is!
 
Just found this on the corsair site if it's of interest:

Disclaimer: The only difference between Type 3 and Type 4 cables is the pinout of the 24-pin ATX cable; all other cables (SATA, PCIe, etc) are the same.

I'd be very wary about mixing 'n' matching or splicing cables unless you're 100% sure you know the pin config for each end, maybe the empty pin is a defunct 'ground' on the +2 of a 6+2? I dunno.

Have you been experiencing any issues with the cable you already have?

They are good quality cables pressuming it's an original corsair one.... It will be designed to carry the load its meant to.

I have 3 Vegas all running off one double cable each... Mining cards but no issues though they are each only drawing about 120w.

Also running the 2070s off a single cable... That's about 180w gaming but no issues either.... I could run two cables but don't to keep things neet in the case.
 
the +2 on the 6+2 corsair PCIE cables is just plumbed into the standard 6 pin plug anyway.

Makes me think it's not really nessesary other than to keep the GPU happy

To clarify things a bit. The psu is a Corsair TX750M and as was bought in a second-hand build it only came with some cables; presently I only have one pcie power cable connected to my 2080 and was wanting another as heard it is better to use two separate cables than just the one.

This is a picture of the pcie power cable that I have bought (connector that goes into psu)

This is (a bad) picture of the present pcie power cable (connector that goes into psu)

As can see the pin layout is different with the new cable that the existing one. The wird thing is that a couple pictures I have seen of corsair pcie power cables is that the layout is like the new one that I have bought rather than my pre-existing one!

Can anyone confirm the layouts to be okay and the same as theirs.

Thanks again.
 
I think the second pic is not a PCIE connector, its a peripheral connector for sata or molex power [EDIT or possibly CPU cable]

Also, if it ain't broke, don't fix it, most cards that have 2x 6+2 pcie, dont really need it unless they under perform.

*normally the cable is thick enough to deliver the power*
 
I'll just quote this for now:

I can post some pics of my very old hx620 and new rm750 cables as I've literally just swapped out my PSU yesterday and have all the cables, but it will have to be tomorrow as i'm heading for bed :)
 
Thanks for replies.

Seeing the pin layouts being different has so far prevented me from using the new cable - I presumed they would/should be all the same layout.

Using the one cable has caused no problems so far; reading posts recently where people have had gpu problems and a common suggestion is to run it on two cables rather than one. Would love to know if it has any difference to the gpu.

I shall continue to run the 2080 on the single existing power cable for now.

In your case there's no difference. Both cables are missing a ground pin, and pcie 8 pin specs for 5x ground pins and 3x 12v pins. The grounds will all be tied together at the psu end anyway, so it makes no difference as to which one is missing :)
