Weird cable problem

I recently bought a Antec Titan 550 Server case and a Asus DSBF-D/SAS
motherboard.

The problem is that the ATX12V1 and ATX12V2 plugs are on the same
cable 10 cm from each other while the connectors on the motherboard
are 30 cm from each other.

Do I just be some kind of extender cable for one of the plugs or is my
hardware simply not compatible - any help would be greatly appreciated

If they're to be of any real use they should be on different 12V rails, so
would it be possible to cut open the sheathing (if any) to give you more
'stretch'?

Careful there!

Are you sure you aren't looking at the 20+4 power cable ? The
main power connector on motherboards used to be 20 pins. When
PCI Express came along, they wanted a few more amps for the
PCI Express slots, so they changed the main connector to 24 pins.

For convenience, power supplies have been shipping with a
"splittable" 24 pin connector. You can disconnect a 4 pin
section on the end of the connector, thus allowing the
remaining 20 pin section to be plugged into an older 20 pin
motherboard. The 4 pin section is left dangling.

Since the cabling between the 20 pin section and the 4 pin
section you quote, is so short, my guess is the 2x2 you
are looking at, is the wrong one.

The ATX12V 2x2 processor connector, has two yellow wires and
two black wires. (For 12V and GND respectively.) That is
the one you want for the processor.

The 4 pin extension section of the main power connector, has
four wires of different colors. You don't want to plug that
into the processor 2x2 ATX12V connector socket.

This one *does not* go to the 2x2 processor power:

This 2x2 is used by the processor. The four wire cable should be
a separate one.

Hi Peter thx for you help.

The problem is that wire from one plug (the 2x2 one) goes into the
back of the other one. I can see how I can seperate them.

Hi Paul thx for your help

The big power cable is 24 pin (it can't be taken appart) so I don't
think that is the problem. The 2x2 looks exactly like the last picture
you posted but the 10 cm of wiring goes into the back of the other 12
v plug (2x4 pin).

RTFM! It may not require both connectors. Not All PSUs have the 8pin
connector, so the 4way may be there for PSU with only 4way. It sounds like
it is the same rail to both plugs frfom what you said earlier.

I should have looked up the board before answering. It is a server board,
and uses a 24 pin, a 4 pin (for memory power) and an 8 pin (dual processor).

So both a 2x2 and a 2x4 are required.

When you look in the picture here, the placement is kinda bad, if both
cables are sheathed together. Some of the other DSBF versions have the
2x2 connector, closer to the 2x4.

Antec Titan 550W - shows a Truepower 2.0 supply inside.

One of the reviewers here, notes that the 12V cable has both a 2x2 and
a 2x4 connected to the end, implying the Truepower supply has been
modified a bit from the description I saw originally for it. So the
OP has run into the exact same problem.

The pictures of the Truepower, usually show tie wraps used to hold
the cable assemblies together. If that is what is preventing the cables
from being further apart, you could cut the nylon tie wraps.

A Silverstone SST-PP01 extension kit, comes with a 2x2 extender, but it
is only 6" long. It might take a couple of these, so the cable can
reach.

The OP could always remove the original supply, and get something decent.
This unit would be a good choice. And no question whether this has
enough current on the 12V rail, as it is a single rail output.

Thx so much for your reply paul it was really helpfull. I just ordered
some silverstonetek extention kits which will hopefully work otherwise
I will buy a new powersupply.
