Electrical Genius Wanted: Need to make a 6pin modular psu cable for my mobo - will this work?

I have an Asus z87-WS mobo and a Corsair AX1200 PSU.

The mobo requires a 6pin ATX cable which goes right above PCIe1 in order to power my tri sli config (3 580s watercooled).

The only available slots left on my PSU are the 6pin slots under "sata and peripherals". Normally the 6+2 pins that I've used on my GPUs have gone in the 8pin slots on my PSU but these are all filled.

Would it be fine to make a 6pin cable from the wires of an 8pin cable? I have the appropriate 6 pin headers. Just want to make sure that this will not fry my new mobo.

Asus Manual
Page 53 - The EATX12V_1 is the 6pin on the mobo that im talking about. Needs 3 grounds and 3 +12V DCs.... not sure if my psu will have that

"RAM GUY" on this forum Here says that the AX1200 is a single rail design so all slots get power from the same source - does this mean the 6pin cable will work fine?

Thanks!

Thanks. To add more detail I would be making the 6pin from this cable.

I would use a 6pin header from an extra ax1200 cable. And a different 6pin header for the mobo - since the keys are different. Just worried since the keys are there for a reason..

EATX12V_1 6-pin connector is for graphic cards 12V power supply plug. When using
high-end or more graphic cards, more power may be needed. Use this connector to
enhance power by 12V.

Only needed if your running extreme graphics from what i've read.

What are you going to run for a GPU card or cards

EATX 12V_1 is a standard 6-pin PCI Express Supplementary power connector socket on the motherboard.

You can plug in a 6-pin (or the 6-pin portion of a (6+2)-pin) PCI Express supplementary power connector from the power supply unit directly into that socket.

There's no need to make a cable.

Yeah the thing is that I dont own a 6pin to 6pin modular cable (all 6+2 are being used ATM), so was wondering if I could make one from a spare 8pin and just fill the 6pin header with the 8pin cables and connect it to the 6pin slot on the ax1200 without it frying anything..

Apparently the 6pin to 6pin modular psu cable is hard to find online without buying a psu - so would rather just make one.

Am I correct that you are saying this wouldn't be a problem then?

Running 3 gtx580s in sli (with ek water blocks) - each card requires one 8pin and one 6pin (from the 6+2). So six of the eight 8pin slots are filled by gpus - the other two are filled by the 2 CPU power 8pins.

So im left with the three available 6pins under "sata and peripherals"...

Those connectors would be supplying +3.3V, +5V and +12V.

You could use a dual 4-pin Molex peripheral to 6-pin PCI-E adapter cable like the ones included in some graphics card packages. Those adapters just tap into the +12V power line and ground connections from the PSU.

I have a fee of those cables. I read though that you want each of the 2 molex ends to connect to a seperate "daisy chain" molex cable. In other words, have 2 seperate molex cables coming from the psu that each molex head of the Y splitter will connect to. Is that true? Also this psu is a single 12v rail - does that change things?

Even a single modular peripheral cable with four 4-pin Molex connectors on it will do. Use two modular cables if you want with each 4-pin Molex connector of the adapter cable connected to each modular cable. Single +12V rail makes things easier since you never need to worry about load balancing.

Sorry to beat a dead horse but just to confirm. So i can plug a 6pin/2molex Y splitter into two molex connectors on a SINGLE modular cable and that will give enough juice to power the 6pin mobo slot? Thanks - after your reply ill give you the best answer!

Yes.

The point of that 6-pin PCI-E socket on the motherboard is to be able to supply up to 75 Watts (or 6.25 Amps) extra on the +12V power lines in the motherboard's PCI Express slots, if the graphics cards even need it.

Haha thanks - and yes it was a learning experience, extra cautious now because of the new board. I have my build log from 2 years ago with pictures and a you tube video - it's changed a bit since then (new CPU/mobo/3 gpus - no front panel screen) but the overall black gold theme is the same. New mobo is extra gold - looks real nice. ill be updating new pictures to the build log when it's done in a few days.

So finally done with the modifications to the build - all the electrical stuff works great and also reduced my dual loop to a single loop which removed alot of clutter. Thanks again for all your help guys!

Runs perfectly - I looked into this mobo for awhile to ensure it could handle 3 580s and a sound card - plus the color scheme is spot on! Couldn't ask for a better mobo. Still working on the OC but will circle back later with the results. Thanks for the kind words!
