Computer assembly - help needed

[Overread16 4]

Ok so I'm trying to connect a Coursair RM 750 to an Asus Z87 Pro and there's a problem.

The supplied CPU cable with the power supply appears to have to ends to it, of which only one will connect to the PSU (by virtue of a thin clip, the other end has a thick locking clip that won't fit into the slot on the PSU). However the motherboard has an arrangement of square and rounded edge slots that is different from the pattern found on the end of the CPU cable that is to plug into it.

I'm assuming either that its ok to plug rounded edge into square edge - or (far more likely) that I need a different cable than the one supplied?

Pics would help since all that stuff varies.

I build on the side everything is plug and play. A round plug wont fit in a square fitting pretty much answered your question there although all cables are suppose to come with new motherboard packaging. did you buy it new? Post some pics if you can so we can get a better idea.

That's a fully modular power supply, so it should have come with a collection of cables (7-ish?) that plug into the PS on one side and into a range of other devices. One of them should fit your MB on one side. There are actually two connectors on the MB you need to worry about, but both connectors are standard arrangements -- the big 24-pin connector should be really easy to find, and the other one is an 8-pin connector for the CPU.

I have read some reviews that said that the 24-pin ATX connector, in particular, didn't seem to seat very well. It might be worth calling Corsair -- they might send you a replacement if it's really not fitting right.

Here are the two parts:

A - the cable connector from the power supply, note this end won't fit into the power supply unit because of its thicker locking tab.

And this is the port on the mother board. Note that the end of the PSU cable that does fit into the PSU does also fit onto this connection point without any problem

You need a new cable.

 

[Overread16 4]

Darn it - do you know the name of the cable per chance? I assume its a standard fitting cable type

 

[runnah]

8 Pin PCI Express cable. Although I am having trouble finding the exact configuration.

 

[Overread16 4]

Yeah, I think it might be a female to female which sounds odd but the female connection ends appear to be the type used from what i can see

Check this out:

All about the various PC power supply cables and connectors

The cable you've got should fit that connector. It appears to be an EPS (CPU) cable -- even though it's only got the two full-square connectors, they're in locations that guarantee that you can't use that cable as an 8-pin PCIe cable.

You do not want an 8-pin PCIe cable -- these are for power-hungry video cards. Although they're both 8-pin connectors, they're designed to be plug-incompatible with respect to one another.

If in doubt, call Corsair - maybe they can explain why they only use the two square pins in the EPS cable.

 

[runnah]

Ahh my mistake.

Thanks lambertpix- I'll give Corsair a contact to make 100% sure but you are right that the squares I do have do line up.


In other questions just two simple ones now'
I've a C-link output on the PSU and a slot on the tower that fits one of its output lines - though oddly I've no mention in the Tower instructions as to what this cable is for. I assume the two go together though I'd like to know why.


SATA connections - I've got 6 Intel SATA connectors and 2 ASMedia SATA connectors on the mother board. It doesn't state anything other than that the Intel one can be used for a RAID whilst the ASMedia can only be used for Data Drives. I've 3 drives to connect - one SSD for the OS and two additional regular HD drives.
I assume I use the Intel connection points for all 3 - with slot 1 for the SSD of course.

Ok, depending on your motherboard the power connector for it will generally either have 20 pins, or 24. Older style motherboards used only a 20 pin connector, the newer ones use 24. Most modern power supplys spllit the main board's power connector for this reason, the main connector will be 20 pins and their will be an additional seperate connector that you can put together with the 20 pin connector to make a 24 pin connector. Usually they slide together, it's generally easier to put them together before pluging them into the motherboard

The asus motherboard you have will have the 24 pin style connector so you'll need to put the two together from the power supply to power up the motherboard properly. You'll also probably have a 4 pin connector elsewhere for additional power to the CPU that will have to be connected as well so be on the lookout for it, it's generally located somewhere near the CPU slot on the motherboard.

Thanks for the input robins - though the 24 pin wasn't the problem, it was the missmatched connections on the other line which is an 8 pin. After the above mentioned it appears that they've done this to be backward compatible with other motherboard connections, so this is a case where the round slot goes into the square.

Also answered my own SATA question - the two spare slots are there for additional expansion once the standard 6 are full.
