pcie to cpu cable adaption

[nikola111]

I am interested ether this will work or not, I just rearranged the cables.
I have v formula z motherboard and x1250 seasonic psu.

Edit: I would just use white one, 4pin atx

In short: Hell no. They are keyed differently and you can really mess up your system that way. See how the yellow powered wires and black ground wires are reversed top-to-bottom? Read this article for more details:

You shouldn't even be able to plug one into the other, which is why they have the squared vs. rounded shapes of the plugs - but you can probably do it if you force it. But don't do that.

No, never attempt that.

White is atx connector from old psu and it is compatible with MB, I thought if I have 12v and ground on wires on gpu cable, if i connect them in right way thay can be used as extra 4pin atx for 8350 that i itend to overclock.
This is one of original cables of seasonic that can be connected on psu (labeled pcie/cpu) and has pcie connector (I lost this cable).
This cable goes to 8 pin that i have connected, i just need 4pin atx so i used one of extra pcie cables that I have and rearanged wires, should it work with that logic? Also I red that same link couple days ago.

Edit: Isnt it connected right, 12v and ground as it should?

Really, you should not even try that.

I'm assuming by the "PCIE/CPU" connector you mean the top-right plug on this:

And what that means is that you can plug a PCIE cable into the power supply (on the left) OR a CPU cable (on the right). NOT that you can use a PCIE cable as a CPU cable.

I don't understand the purpose of this anyway. That PSU should have an 8-pin CPU power cable included. Do you not have it anymore? If not, just use the 4-pin cable for now and try to get a replacement for the 8-pin. This is not a situation where you want to freelance. You will ruin your system.

I do have 8pin connected but MB has 8pin + 4pin. I need to connect 4pin for extra supply in orderd to overclock it.
I also found this http://www.amazon.co.uk/akasa-AK-CB051-PCIe-ATX-adapter/dp/B0027FFRQI
Thouth if 12v grid is same for pcie/atx/molex that I can arrange cables and thats it (red that somewhere)

I dont use fabric pcie for cpu,I use one end of it and second I rearange cables so they should be fine for cpu(use some of cables and put them in whit jack in pictures above so can fit nice in MB)?

If you have the 8-pin connected already, there is no need for the additional 4-pin. The motherboard only has both plugs in case your PSU only has one or the other.

The 8-pin cable by itself supplies up to 235W, and there is no way your CPU is going to use that much even with an extreme overclock.

 

[nikola111]

In guidebook they say it can work with eather or if overcloking then both, like molex on board for extra power in case of SLI or so. Ll try to overclock like this, hope gonna be stable couse that missing cabble gonna make me trouble.

 

[capt_taco]

I really don't see how you could go over the amount of power the 8-pin cable can provide.

There would be no harm in plugging in both the white 4-pin ATX and the 8-pin ATX at once, just don't try to use a PCIe connector as a CPU connector. Originally it sounded like the thread was about trying to use a PCIe 6+2 to plug into the motherboard, but if that's not what you're doing, then by all means connect both CPU plugs.

 

[nikola111]

I do understand that now, just wondering if this cable would work? I got out wires from 6+2prcie as u see and put them in "correct" way in old whit atx jack(plastic, sorry on bad english).I didnt intend to use these 6+2 connectors just white ATX as extra power supply cable. I ll try without it but in case of unstable voltage, what u think, should this work?

 

[capt_taco]

Oh, I see - you rewired it into an old ATX plug. Maybe that'd work, but I would only try it if you had no other options and were REALLY confident you knew what you're doing. Much safer to try and get a replacement cable.

I don't think you'll come anywhere near needing the 4-pin, though. Even up in the 5 GHz range, you shouldn't be pushing what you can get out of the 8-pin alone.

 

[nikola111]

Going for 5+GHz if possible. Just got new cooling kit, 360mm*60mm for cpu only and sp120 HP edition so cooling shouldnt be problem.
I live in Europe, eastern country and only way to get cables is to bay whole set that would cost me 45$. Cant find now, but not long time ago I saw something like this. I didnt try to connect, dont want to white smoke, but ll look around a bit more to see what others think. Thanks for answers, best regards

(electronics work on white smoke, when it gets out its dead)
