Power Supply connecting help Tags: Power Supplies Connection Motherboards Components Last response: December 22, 2010 1:39 PM in Components Share Trioxin December 22, 2010 8:29:33 AM So, I'm in the middle of building a pc and I'm a bit stumped with power supply. It says to connect 24 pin cable to motherboard. So, does it matter which way I connect it? Also, on the other end of that cable are 5 and 9 pin connectors. Do I connect them to PSU? PSU is Corsair 750W AX and motherboard is X58A-UD3R.

That is the right way. You would see a small latch on one side of the 24 pin connector, which fits into a small hook like thingy on the 24 pin socket of the motherboard. You just align that and you should be ok. AFAIK, there are no odd numbered pin connectors in a PSU, do you mean 4 pin and 8 pin connectors? Trioxin December 22, 2010 9:00:06 AM Ah, sorry, on the other end of that 24 pin cable are 10 pin and 18 pin cables.

They are from the older ATX12V v1.3 connectors. Since ATX v2.0 all motherboards have 24 pin power connectors. kikireeki December 22, 2010 10:31:53 AM The 10 and 18 pins connectors should be plugged into the power supply and each pin has a special socket shape and you can't plug them in a wrong way even if you try to! Trioxin December 22, 2010 12:53:18 PM Yup, did just that. One was above the other, so they fit nicely. Also, I used 4+4 to connect that motherboard 12 V 8 pin slot, will that be ok? hell_storm2004 a b ) Power supply a b V Motherboard December 22, 2010 12:56:09 PM It should. But there should be a one piece 8 pin connector shouldn't it? Check your PSU connectors. Trioxin December 22, 2010 1:00:05 PM I did try that one, but it was a hard with becuse or hole shapes, and it's really hard to reach (thanks noctua). So I managed to put that one. I did manage to boot pc and enter bios. Just so I don't create another topic. I also got a message, Disk Read Error. Insert system disk and press enter. But I presume beacuse it's new disk and there is nothing on it. hell_storm2004 a b ) Power supply a b V Motherboard December 22, 2010 1:02:44 PM The error you mention is because of no boot loader i think. It should go away once an OS is installed or a bootable DVD/CD is inserted. Check what is your first boot device in BIOS. I think it is set to DVD/CD. Trioxin December 22, 2010 1:12:25 PM Can't check right one... working But I think hdd is first boot device. Also hdd is SATA while DVD is IDE. hell_storm2004 a b ) Power supply a b V Motherboard December 22, 2010 1:14:34 PM Then i think you should go ahead and install an OS. If you are installing the Win XP, then you must have to install the SATA drivers first. For that you need a floppy drive. Trioxin December 22, 2010 1:25:23 PM Don't thinks so. Don't even know what HSF stands for. Is it Corsairs forum? Trioxin December 22, 2010 1:39:37 PM Nope, it's not me than @Hell_Storm Yup, I'll install it tonight or tommorow, thanks for all the help.
