So today I took the day off to set up my new computer, I bought myself a Corsair AX750 Modular powersupply and a new Corsair 600T graphite white case. but I have some problems... I have been sitting here making it look all neat and tidy wiring it up and when I am done BAM I can't turn it on. So it worries me because I have never plugged up a modular PSU before so whether or not I have gotten the wiring wrong I don't know but here is the thing. My motherboard is the MSI 870-C45 AM3 socket board and it has a 24 pin socket yet my old powersupply ran it with a 20 socket plug (non modular, 500w Elite it came with the Coolermaster 430 case) so I am stuck right now wondering what to do... Have I plugged the LED's in wrong? Can someone help me on how to plug them up correctly and the same with the modular PSU.

Thanks,

Max

Plug in a 24pin ATX from the PSU (20+4pin) into the board.

Up near the CPU is another socket usually 4 or 8pin, take a 8pin ATX from the PSU and plug this in, if its only a pin socket, split the 8pin from the psu into two.


LEDS dont matter now, that wont stop a PC turning on.

Ity also doesnt matter which way around the reset switch pins or power switch pins go as all they do is quickly short the two pins together they are connected too.

If you have a GFX card that needs additional power into the side of it, use PCI-E connectors from the PSU and fill them all up (whether it be 6pin, two 6pins or a 6+8pin)

A detailed list of your parts will also help.

Judging by everything you have approached me with, it is all looking A OK. what worries me is what I have plugged in to the actual PSU, which I will take pictures of and post up right now.
 
Here are the pictures of what I mean, the ATX cable in red is what I have plugged in and its only 18 pin which confuses me, then there is a 10 pin which is highlighted in yellow on the same cable. and finally the blue highlight is to show where I have plugged the 18 pin in too.





and another for example



Thanks for your help,

Max
 
Plug both those (18+10) into the PSU, there is a 10 slot with a 8 slot underneath it on the unit.


Then you have a 4/8 ATX pin next to the cpu cable that ends in a?

Thanks for the help stulid and I think we are a step ahead but i appears that didn't resolve the issue which brings the question up of what next? :S
 
The motherboard needs additional power to the CPU via a 4pin or pin socket?

There are two cable for this (called EPS12V/ATX12V) just use one cable, the end will split from 8pin into two 4pins depending on the motherboard needs.
 
GFX card needs two 6pin into it, these end in 6pin at the other end? plug these into the PSU as well.
 
If you have made sure it's pluged in to the mains you could try the paperclip test.

It's a tad harder with that PSU as the wire are not colour coded, but if you look on the video you can see what holes he used.

Best to disconnect the PSU from the PC first though, and just attach a fan to the molex, so you can see if it powers up as the cpu fan won't run at low output.
 
It lloks like you havent got any wires connected to the motherboard header for POWER/RESET /LED etc.

Ignore that, I can see them in the top picture.

do you mean the ones for JFP1 or JFP2? Because all the small ones i.e Power LED + -, HDD LED, Power switch and reset switch are all plugged in to JFP1. In this order..

PWR LED | PWR Switch |
+ -
HDD LED | Reset Switch

edit: There are these two pin cables that need the caps pulling off them also. I have used them as my power for my fan's. Is that what I am doing wrong?

I just noticed the cables in one of your first pictures:)

All you need to do to start a PC is quickly short these two pins (highlighted) using a flat blade screw drive

So you could unplug everything thats not needed yet.
